Dynabeads™ His-Tag Isolation and Pulldown Invitrogen™

This product is designed for his-tagged protein isolation. High selectivity for poly-histidine tags results in extremely low background levels. The new bead surface chemistry is Cobalt-based and offers exceptionally fast binding kinetics and a high yield per microliter of beads. The entire protocol (from cleared lysate to purified protein) takes only 20 minutes! The protocol includes instructions for making the required buffers as well as methods for optimizing buffer composition. Dynabeads® His-Tag Isolation & Pulldown replaces Dynabeads® TALON™. Dynabeads® His-Tag Isolation & Pulldown has a new optimized binding chemistry that offers significant advantages over Dynabeads® TALON™ which were coated in the TALON™ chemistry. This optimization results in a cleaner prep with higher yield of his-tag protein and extremely low background levels. Dynabeads His-Tag Isolation & Pulldown is designed for isolating His-tagged proteins from cleared lysates. Isolated his-tagged proteins can either be eluted from the beads or kept on the beads for use in bead-based downstream assays. Bead bound his-tagged proteins can be used in various downstream assays such as bait-prey pulldowns, etc. Note: This product contains Dynabeads and a protocol only, and does not include buffers. The technology used for the discontinued Dynabeads® TALON™ was licensed from Clontech. TALON™ is a registered trademark of Clontech Laboratories Inc., USA.

Dynabeads™ Co-Immunoprecipitation Kit Invitrogen™

Dynabeads® Co-Immunoprecipitation Kit allows easy coupling of an antibody of your choice to the surface of uniform, 2.8 µm superparamagnetic Dynabeads® M-270 Epoxy beads. Following immobilization of your antibody, use the coupled beads and the buffers supplied in the kit for co-immunoprecipitation (co-IP) of proteins, intact protein complexes, or intact protein-nucleic acid complexes and to elute those complexes from the beads. In addition to Dynabeads®, the kit supplies the buffers needed for efficient antibody coupling, gentle washing, and elution of the co-isolated protein complexes.

• Optimized buffers and Epoxy-coated Dynabeads® for efficient co-IP included in the kit
• Gentle separation technology: preserves native protein conformations and large-protein complexes
• Covalent antibody coupling to the Dynabeads® avoids co-elution of the antibody with the target proteins

Efficient, easy coupling
Antibodies are covalently coupled to Dynabeads® M-270 Epoxy beads, minimizing the risk of bound antibody contaminating your final eluate. Dynabeads® M-270 Epoxy beads exhibit ultra-low background binding and don't require blocking before use. The supplied buffers are optimized to give consistent and reliable results and the kit includes 8 different binding, washing, and elution buffers, in addition to Dynabeads® M-270 Epoxy to enable you to purify complex protein structures of any size. All kit components are analytical grade and are compatible with protease and phosphatase inhibitors. The only thing you need to supply is the antibody of choice. The protocol describes coupling, sample preparation (detergent and cryolysis methods), co-IP and elution, and is compatible with western blot/silver stain, Coomassie™ stain, mass spectrometry, or extraction of nucleic acids from isolated DNA/RNA binding protein complexes.

Magnetic bead-based separation offers easy handling
Captured proteins and protein complexes are easily separated, washed, and eluted using a DynaMag™ magnet, and the magnetic separation properties of the Dynabeads®. The kit is designed for and tested with cultured yeast and mammalian cells and is compatible with tissue, insect, bacteria, and othe lysates.

Dynabeads™ Protein A Immunoprecipitation Kit Invitrogen™

The Dynabeads™ Protein A Immunoprecipitation Kit is a faster and easier solution for immunoprecipitation (IP) than using Sepharose™ resin or agarose resin, and includes all reagents and buffers required to perform IP using your own antibody. The kit is optimized for standard IP, but can also be used for Co-IP, chromatin IP (ChIP), or RNA IP (RIP). The kit includes the widely used Dynabeads Protein A with recombinant Protein A (~45 kDa) covalently coupled to the magnetic bead surface. Both manual and automated protocols are available.

• IP in less than 40 minutes
• High target protein yield with low antibody consumption
• Very low non-specific binding with high signal-to-noise ratio
• No columns, centrifugations, or time-consuming pre-clearing required
• High reproducibility with Dynabeads Protein A and all buffers supplied in the kit
• High throughput compatible with KingFisher™ instruments

Manual Dynabeads separation is fast and easy to perform
The manual protocol is simple and can be performed in under 40 minutes. First, the antibody for the target protein is incubated with the Dynabeads Protein A in a tube for 10 minutes. Excess antibody is washed away by placing the tube in a DynaMag™ magnet and removing the supernatant. The antibody-coated beads can then be used for a variety of downstream applications including IP, Co-IP, chromatin IP (ChIP), RNA IP (RIP), small-scale IgG purification, and protein purification. Bound material is easily collected using a DynaMag magnet due to the unique magnetic properties of the Dynabeads. The recombinant protein A on the beads contains no albumin binding sites, thus albumin is not co-purified during the procedure. The IP is fast and gives high yield, high reproducibility, and very little non-specific binding, thus pre-clearing is not required.

Automated Dynabeads separation helps increase throughput and reduces hands-on time
If you are working with several samples in parallel, the number of washing steps and the hands-on time increases proportionally with the number of samples. Pipetting and other manual handling tend to be less consistent than automation when working with many samples at a time. To better handle a medium- to high-throughput number of samples, reduce hands-on time, and secure high reproducibility, we have developed IP protocols for the KingFisher Flex and KingFisher Duo Prime instruments. The automated protocols replicate the manual protocols, obtaining equally high target protein yield and the same low non-specific binding and high reproducibility. It doesn’t matter if you are working with 10 or 96 samples, the IP protocol is less than 40 minutes regardless. Just load the reagents on the plates, push the “Start” button and by the time you have prepared for downstream analysis, the IP is done. Some optimization (e.g., incubation times) might be necessary depending on your antibody and the abundance and/or specificity of your target protein.

• Use the KingFisher Duo instrument for low to medium throughput (1-12 samples/run)
• Use the KingFisher Flex instrument for high throughput (12-96 samples/run)

Gentle separation causes minimal physical stress to proteins
The magnetic separation technology utilized by Dynabeads Protein A is rapid and gentle, causing minimal physical stress to your target proteins. This permits the isolation and concentration of labile composites that might otherwise dissociate or be damaged by proteases during long incubation times. Native protein conformation and large protein complexes are preserved.

Binding strength and capacity
Dynabeads Protein A allow for isolation of most mammalian immunoglobulins (Ig). The amount of Ig captured depends on the concentration of Ig in the starting sample and on the type and source of the Ig. 100 µL of Dynabeads Protein A will isolate approximately 25–30 µg human IgG from a sample containing 20–200 µg IgG/mL. Predominant Fc-binding allows optimal Ig orientation. The antibodies bind to the outer smooth surface of the beads, thus are not trapped in large pores as with Sepharose/agarose-based beads. All antibodies are available for protein binding, so low amounts of antibody are required while still obtaining the same high yield of target protein. The smooth bead surface is also responsible for the low non-specific binding that Dynabeads are known for.
