Total Nucleic Acid Extraction / Protein
Research sometimes requires testing of more than just RNA from each sample. For example researchers may want to compare the effects of genetic variations on gene expression, or to evaluate both protein and cognate mRNA levels. To serve this need, some Ambion purification products are designed to extract both RNA and DNA, or both RNA and protein from samples. Kits with these capabilities allow users to get more out of their samples while employing one kit to streamline the process.
The MELT Total Nucleic Acid Isolation Kit provides a method to obtain RNA or DNA from fresh or frozen tissue without physical digestion. For FFPE samples, the RecoverALL Total Nucleic Acid Isolation Kit for FFPE sets the standard and allows users to purify both RNA and DNA via a conventional filter-based method, while the new MagMAX FFPE Total Nucleic Acid Isolation Kit offers the same RNA and DNA purification from FFPE samples in a magnetic bead format without the need for xylene.
Nucleic Acid & Protein Extraction Kits
The PARIS Kit is designed to simultaneously purify total RNA and generate a native lysate suitable for common protein analysis techniques. The related mirVana PARIS Kit can also be used to obtain both total RNA and native lysate, but it also recovers the small RNA fraction, either along with total RNA or as a fraction enriched for small RNAs.
Total Nucleic Acid Extraction Kits
The MagMAX Total Nucleic Acid Isolation Kit purifies both RNA and genomic DNA with a combined mechanical (zirconia-bead beating) and chemical lysis method designed specifically for hard-to-lyse bacteria. Conversely, the MELT Total Nucleic Acid Isolation Kit provides a closed-tube, enzymatic method to obtain RNA or DNA from fresh or frozen tissue without physical disruption. For FFPE samples, the RecoverALL Total Nucleic Acid Isolation Kit for FFPE is designed to purify both RNA and DNA via a conventional glass fiber filter-based method, while the new MagMAX FFPE Total Nucleic Acid Isolation Kit offers xylene-free RNA and DNA purification from FFPE samples using a magnetic bead method.

Magnetic Bead mRNA Extraction and Enrichment Kits
Oligo(dT)/Magnetic Capture Methods
Column methods for mRNA purification are reliable but require extensive manual interaction, which means more time and reduced throughput. Magnetic beads conjugated with oligo(dT) offer additional handling and scaling benefits; however, this procedure does require the use of magnetic stands.
The Invitrogen Ambion Poly(A)Purist MAG Kit employs the same hybridization and wash solutions as those in the Poly(A)Purist Kit but with the added ease, speed, and scalability of magnetic beads. The protocol typically takes only 45 minutes, and the kit performs from 8 large enrichment reactions (up to 1 mg total RNA input) to 80 small enrichment reactions (as little as 30 µg total RNA input). Like the Poly(A)Purist Kit, this kit only enriches mRNA from previously purified total RNA.
The Invitrogen Dynabeads mRNA Purification Kit for mRNA Purification from Total RNA Preps, enriches mRNA from purified total RNA, typically in 15 minutes, and allows users the flexibility to elute the mRNA from the beads in as little as 5 µL, or even to perform cDNA synthesis directly on the beads without elution.
For those who prefer using Dynabeads technology with sample lysis and enrichment in one kit, the Invitrogen Dynabeads mRNA DIRECT Kits enable 15-minute lysis and enrichment processing of a variety of sample types. In fact, it is possible to capture mRNA and generate cDNA libraries from a single cell using this technology. The flexible format allows users to scale up or down and gives the option to elute the mRNA from the beads in as little as 5 µL, or to perform cDNA synthesis directly on the beads without elution. The 5 mL size is sufficient for 20 standard isolations, while the 10 mL size is sufficient for 40 standard isolations.
For those who work with smaller inputs, the Invitrogen Dynabeads mRNA DIRECT Micro Kit provides enough reagents for 100 mRNA isolations from up to 2.5 x 104 mononuclear cells, up to 1 x 104 cultured cells, or up to 5 mg tissue (depending on the tissue), with the same elution flexibility as the other Dynabeads kits.
Bacteria lack the relatively stable poly(A) tails found on eukaryotic mRNA. Until very recently, isolating mRNA from bacteria has been virtually impossible. The Invitrogen MICROBExpress Bacterial mRNA Isolation Kit employs a novel technology to remove up to >95% of the 16S and 23S rRNA from total RNA of E. coli and other bacterial species. The kit is suitable for mRNA enrichment from ≤10 µg of purified bacterial total RNA in about 2 hours from a broad spectrum of gram-positive and gram-negative bacteria. mRNA isolated with the MICROBExpress Kit is a superior template for synthesizing labeled cDNA for array analysis and is ideal for quantitative RT-PCR, northern blotting, and cDNA library construction.
mRNA Extraction and Enrichment via Coated Plates
The most distinctive mRNA purification method takes advantage of specially treated plates in conjunction with optimized reagents to both lyse and enrich mRNA from cells, tissue, blood, or purified total RNA. The Invitrogen mRNA Catcher PLUS product utilizes a proprietary surface treatment of a 96-well plate to facilitate easy and automation-friendly mRNA purification. Locked Nucleic Acid (LNA) technology incorporated into the 20-mer oligo(dT) increases specificity and hybridization efficiency while removing centrifugation, precipitation, and phase-separation steps from the overall workflow.
The mRNA Catcher PLUS Kit is capable of handling 100 ng to 100 µg total RNA, 100 to 106 mammalian cells, up to 4 mg tissue, and 40 µL whole blood. The binding capacity is >80 ng/well. The protocol employs a simple lysis, hybridization, wash, and elution process that can be completely automated on open-format liquid handlers in approximately 1.5 hours from start to finish. The system also has the flexibility to elute mRNA or to perform cDNA synthesis directly in the hybridization plate without elution.
Sequence-Specific RNA Extraction
Target a specific RNA sequence and isolate only those RNA molecules directly from crude lysates or other biological fluids using Dynabeads. Captured RNA is suitable for a wide range of downstream applications, including Dynabeads Streptavidin are ideal for numerous applications, including purification of proteins, nucleic acids purification, protein interaction studies, immunoprecipitation, immunoassays, phage display, biopanning, drug screening and cell isolation.

Dynabeads Technology
Our Streptavidin-coupled Dynabeads are a robust and versatile tool that can be used to literally target and capture specific RNA or DNA sequences and then pull them directly out of solution. These monosized superparamagnetic Dynabeads provide an efficient and solid-phase alternative to nitrocellulose and provide you with an unmatched level of product quality and data consistency. Excellent near liquid phase reaction kinetics allow for extremely fast protocols. The inherent ease of magnetic handling mean that downstream manipulations and buffer changes are as simple as concentrating the bead-bound target at the tube-wall with a magnet and then discarding the supernatant. These beads are compatible with an extremely broad range of sample types including most bodily fluids, crude lysates of plant, animal and microbial origin as well as purified total RNA or DNA. Since these Dynabeads will only interact with specifically targeted RNA or DNA molecules, upstream purification of total RNA or DNA is almost always an unnecessary step.
The 1 µm Dynabeads MyOne Streptavidin C1 present a very high surface area per mg of beads, enabling high enrichment of low abundance RNA or DNA. When the goal is to capture nucleic acid from more viscous samples such as cerebrospinal fluid, the larger 2.8 µm sized Dynabeads M-270 Streptavidin are recommended. These Dynabeads (MyOne Streptavidin C1 and M-270 Streptavidin) are optimally designed to have slightly negatively charged surfaces which ensure negligible non-specific binding of non-target nucleic acid sequences.
Examples of applications include; isolation of RNA/DNA infectious agent (1,2,3,4), subtractive hybridization (5,6,7), cDNA selection and enrichment, detection and isolation of mutated sequences (8,9,10), isolation of cell specific transcripts and mRNA differential display.

The direct capture procedure involves the immobilization of double-stranded PCR products onto the beads. These are easily converted to single-stranded bead-bound templates which are then used to capture specific RNA or DNA molecules directly from solution.
An alternative indirect capture approach will offer faster reaction kinetics in some cases. This indirect capture procedure allows the target sequence to be captured prior to being immobilized the magnetic beads. First, a biotinylated capture-sequence (single-stranded DNA) is incubated with the sample and allowed to hybridize to the targeted RNA or DNA molecules in solution. Streptavidin coated Dynabeads are then added to the mixture and the hybridized sequences are immobilized onto the Dynabeads via the streptavidin-biotin bond.

Magnetic Bead mRNA Extraction and Enrichment Kits
Oligo(dT)/Magnetic Capture Methods
Column methods for mRNA purification are reliable but require extensive manual interaction, which means more time and reduced throughput. Magnetic beads conjugated with oligo(dT) offer additional handling and scaling benefits; however, this procedure does require the use of magnetic stands.
The Invitrogen Ambion Poly(A)Purist MAG Kit employs the same hybridization and wash solutions as those in the Poly(A)Purist Kit but with the added ease, speed, and scalability of magnetic beads. The protocol typically takes only 45 minutes, and the kit performs from 8 large enrichment reactions (up to 1 mg total RNA input) to 80 small enrichment reactions (as little as 30 µg total RNA input). Like the Poly(A)Purist Kit, this kit only enriches mRNA from previously purified total RNA.
The Invitrogen Dynabeads mRNA Purification Kit for mRNA Purification from Total RNA Preps, enriches mRNA from purified total RNA, typically in 15 minutes, and allows users the flexibility to elute the mRNA from the beads in as little as 5 µL, or even to perform cDNA synthesis directly on the beads without elution.
For those who prefer using Dynabeads technology with sample lysis and enrichment in one kit, the Invitrogen Dynabeads mRNA DIRECT Kits enable 15-minute lysis and enrichment processing of a variety of sample types. In fact, it is possible to capture mRNA and generate cDNA libraries from a single cell using this technology. The flexible format allows users to scale up or down and gives the option to elute the mRNA from the beads in as little as 5 µL, or to perform cDNA synthesis directly on the beads without elution. The 5 mL size is sufficient for 20 standard isolations, while the 10 mL size is sufficient for 40 standard isolations.
For those who work with smaller inputs, the Invitrogen Dynabeads mRNA DIRECT Micro Kit provides enough reagents for 100 mRNA isolations from up to 2.5 x 104 mononuclear cells, up to 1 x 104 cultured cells, or up to 5 mg tissue (depending on the tissue), with the same elution flexibility as the other Dynabeads kits.
Bacteria lack the relatively stable poly(A) tails found on eukaryotic mRNA. Until very recently, isolating mRNA from bacteria has been virtually impossible. The Invitrogen MICROBExpress Bacterial mRNA Isolation Kit employs a novel technology to remove up to >95% of the 16S and 23S rRNA from total RNA of E. coli and other bacterial species. The kit is suitable for mRNA enrichment from ≤10 µg of purified bacterial total RNA in about 2 hours from a broad spectrum of gram-positive and gram-negative bacteria. mRNA isolated with the MICROBExpress Kit is a superior template for synthesizing labeled cDNA for array analysis and is ideal for quantitative RT-PCR, northern blotting, and cDNA library construction.
mRNA Extraction and Enrichment via Coated Plates
The most distinctive mRNA purification method takes advantage of specially treated plates in conjunction with optimized reagents to both lyse and enrich mRNA from cells, tissue, blood, or purified total RNA. The Invitrogen mRNA Catcher PLUS product utilizes a proprietary surface treatment of a 96-well plate to facilitate easy and automation-friendly mRNA purification. Locked Nucleic Acid (LNA) technology incorporated into the 20-mer oligo(dT) increases specificity and hybridization efficiency while removing centrifugation, precipitation, and phase-separation steps from the overall workflow.
The mRNA Catcher PLUS Kit is capable of handling 100 ng to 100 µg total RNA, 100 to 106 mammalian cells, up to 4 mg tissue, and 40 µL whole blood. The binding capacity is >80 ng/well. The protocol employs a simple lysis, hybridization, wash, and elution process that can be completely automated on open-format liquid handlers in approximately 1.5 hours from start to finish. The system also has the flexibility to elute mRNA or to perform cDNA synthesis directly in the hybridization plate without elution.
Sequence-Specific RNA Extraction
Target a specific RNA sequence and isolate only those RNA molecules directly from crude lysates or other biological fluids using Dynabeads. Captured RNA is suitable for a wide range of downstream applications, including Dynabeads Streptavidin are ideal for numerous applications, including purification of proteins, nucleic acids purification, protein interaction studies, immunoprecipitation, immunoassays, phage display, biopanning, drug screening and cell isolation.

Dynabeads Technology
Our Streptavidin-coupled Dynabeads are a robust and versatile tool that can be used to literally target and capture specific RNA or DNA sequences and then pull them directly out of solution. These monosized superparamagnetic Dynabeads provide an efficient and solid-phase alternative to nitrocellulose and provide you with an unmatched level of product quality and data consistency. Excellent near liquid phase reaction kinetics allow for extremely fast protocols. The inherent ease of magnetic handling mean that downstream manipulations and buffer changes are as simple as concentrating the bead-bound target at the tube-wall with a magnet and then discarding the supernatant. These beads are compatible with an extremely broad range of sample types including most bodily fluids, crude lysates of plant, animal and microbial origin as well as purified total RNA or DNA. Since these Dynabeads will only interact with specifically targeted RNA or DNA molecules, upstream purification of total RNA or DNA is almost always an unnecessary step.
The 1 µm Dynabeads MyOne Streptavidin C1 present a very high surface area per mg of beads, enabling high enrichment of low abundance RNA or DNA. When the goal is to capture nucleic acid from more viscous samples such as cerebrospinal fluid, the larger 2.8 µm sized Dynabeads M-270 Streptavidin are recommended. These Dynabeads (MyOne Streptavidin C1 and M-270 Streptavidin) are optimally designed to have slightly negatively charged surfaces which ensure negligible non-specific binding of non-target nucleic acid sequences.
Examples of applications include; isolation of RNA/DNA infectious agent (1,2,3,4), subtractive hybridization (5,6,7), cDNA selection and enrichment, detection and isolation of mutated sequences (8,9,10), isolation of cell specific transcripts and mRNA differential display.

The direct capture procedure involves the immobilization of double-stranded PCR products onto the beads. These are easily converted to single-stranded bead-bound templates which are then used to capture specific RNA or DNA molecules directly from solution.
An alternative indirect capture approach will offer faster reaction kinetics in some cases. This indirect capture procedure allows the target sequence to be captured prior to being immobilized the magnetic beads. First, a biotinylated capture-sequence (single-stranded DNA) is incubated with the sample and allowed to hybridize to the targeted RNA or DNA molecules in solution. Streptavidin coated Dynabeads are then added to the mixture and the hybridized sequences are immobilized onto the Dynabeads via the streptavidin-biotin bond.
