Note: Also available as a FastDigest enzyme for rapid DNA digestion. Isoschizomers: BpmI.

Thermo Scientific conventional restriction endonucleases are a large collection of high quality restriction enzymes, optimized to work in one of the buffers of the Five Buffer System. In addition, the universal Tango buffer is provided for convenience in double digestions. All of the enzymes exhibit 100% activity in the recommended buffer and reaction conditions. To ensure consistent performance, Thermo Scientific restriction enzyme reaction buffers contain premixed BSA, which enhances the stability of many enzymes and binds contaminants that may be present in DNA preparations.

Features:

• Superior quality—stringent quality control and industry leading manufacturing process
• Convenient color-coded Five Buffer System
• Includes universal Tango buffer for double-digestions
• BSA premixed in reaction buffers
• Wide selection of restriction endonuclease specificities

Note:
Incubation at 37°C results in 70% activity.
GsuI requires only Mg2+ for its activity, but is stimulated by S-adenosylmethionine. 0.01 mM S-adenosylmethionine gives a 2-fold increase in activity.
GsuI may remain associated with the cleaved DNA. This may cause DNA band shifting during electrophoresis. To avoid atypical DNA band patterns, use the 6X DNA Loading Dye & SDS Solution for sample preparation or heat the digested DNA in the presence of SDS prior to electrophoresis.
GsuI is blocked by overlapping dcm methylation. To avoid dcm methylation, use a dam-, dcm- strain, such as GM2163.
For methylation sensitivity, refer to product specifications.

AccuPrime™ GC-Rich DNA Polymerase Invitrogen™

AccuPrime™ GC-Rich DNA Polymerase is designed to provide high-yield, high-specificity amplification of difficult-to-amplify templates, such as those with >65% GC content. The kit offers a choice of buffers for amplifying genomic DNA targets (Buffer A) or non-GC-rich cDNA, plasmid, and lambda-based targets (Buffer B). Benefits of using AccuPrime™ GC-Rich DNA Polymerase:

Yield—high yields for targets up to 5 kb in length
Specificity—AccuPrime™ accessory proteins for improved PCR specificity
Sensitivity—sensitivity down to 5 ng of template DNA

Robust and specific amplifications
The AccuPrime™ buffers contain thermostable proteins that enhance primer-template hybridization during PCR, increasing the specificity of the reaction. The polymerase itself, from the archaebacterium Pyrolobus fumarius, has a five-fold better processivity than Taq DNA polymerase, and remains active even after 4 hours at 95°C.

Unit definition
One unit of AccuPrime™ GC-Rich DNA Polymerase is the amount of enzyme required to incorporate 10 nmoles of dNTPs into acid-insoluble material in 30 min at 74°C.

FastDigest PstI Thermo Scientific™

Thermo Scientific FastDigest PstI restriction enzyme recognizes CTGCA^G site and cuts best at 37°C in 5–15 minutes using universal FastDigest Buffer. Isoschizomers: BspMAI.

Thermo Scientific FastDigest PstI is one of an advanced line of fast restriction enzymes that are all 100% active in the universal FastDigest and FastDigest Green reaction buffers.

The universal buffer allows rapid single-, double-, or multiple DNA digestion within 5–15 minutes eliminating any need for buffer change or subsequent DNA clean-up steps. See Reaction Conditions for FastDigest Enzymes for a table of enzyme activity, heat inactivation and incubation times for this and other FastDigest restriction enzymes. DNA modifying enzymes, such as Klenow Fragment, T4 DNA Ligase, alkaline phosphatases and T4 DNA Polymerase all have 100% activity in FastDigest Buffer. Therefore, enzymes for downstream applications can be directly added to the FastDigest reaction mix.

For additional convenience FastDigest Green Buffer includes a density reagent and two tracking dyes for direct loading of digestion reaction products on gels.

Short incubation times and optimal composition of the universal FastDigest Buffer eliminate star activity effects.

Features

• 100% activity of all FastDigest enzymes in the universal buffer
• 100% buffer compatibility with downstream applications
• Complete digestion in 5–15 minutes
• Direct loading on gels
• No star activity
• 176 FastDigest enzymes available

Applications

• Molecular cloning
• Restriction site mapping
• Genotyping
• Southern Blot
• Restriction fragment length polymorphism (RFLP)
• SNP analysis

Note: The FastDigest Green Buffer offers the same high performance in DNA digestion and downstream applications as the colorless FastDigest Buffer. For applications that require product analysis by fluorescence excitation (e.g. concentration measurements in UV light) the colorless FastDigest Buffer is recommended.

For methylation sensitivity, refer to product specifications.

DpnI will only cleave fully-adenomethylated dam sites. Hemi-adenomethylated dam sites DpnI cleaves 60X more slowly. DpnI, Bsp143I, and MboI all recognize the same sequence, but have different methylation sensitivities and cleavage sites. Assayed using pBR322 DNA.

Anza™ 67 RruI Invitrogen™

5'  T  C  G ↓C  G  A   3' 
3'  A  G  C ↑G  C  T   5' 

Invitrogen™ Anza™ 67 RruI is a restriction enzyme that cuts DNA at this recognition site: TCG^CGA, completely digesting the DNA in 15 minutes at 37°C. Isoschizomers include: Bsp68I, BtuMI, NruI.

For superior convenience, a single buffer and protocol are used with all Anza™ restriction enzymes. The single Anza buffer allows multiple restriction enzymes to be used simultaneously in one reaction. This helps eliminate the need for sequential digests and the DNA clean-up necessary when changing buffers. Additionally, the Anza buffer and restriction enzymes have been designed for flexibility in digestion times. Digestions of up to 16 hours can be carried out without star activity.

Convenient—all Anza enzymes are 100% functional in the single Anza buffer
Fast—complete digestion in 15 minutes
Flexible—overnight digestion without star activity
Simple—a single digestion protocol for all DNA types
Complete system—incorporates Anza DNA Modifying Enzymes for a complete cloning experience

Anza DNA Modifying Enzymes include the Anza T4 DNA Ligase Master Mix, Anza Alkaline Phosphatase Kit, Anza T4 PNK Kit, Anza DNA Blunt End Kit, and Anza DNA End Repair Kit. Use these enzymes for a complete cloning workflow.

Anza Red Buffer, which contains a density gradient and tracking dyes, is supplied for added convenience. Digestion reactions are as efficient in the Anza Red Buffer as in the Anza Buffer. Use of the Anza Red Buffer helps reduce pipetting steps when preparing multiple digestion reactions and a subsequent step includes agarose gel electrophoresis. For applications that require product analysis by fluorescence excitation, the colorless Anza Buffer without the tracking dyes is recommended.
