Thermo Scientific™ Pierce Co-Immunoprecipitation Kit provides all the components necessary to perform a properly controlled co-IP experiment and obtain purified products without antibody contamination.
The Co-Immunoprecipitation (Co-IP) Kit enables isolation of native protein complexes from a lysate or other complex mixture by directly immobilizing purified antibodies onto an agarose support. Co-IP is a common approach to study protein:protein interactions that uses an antibody to immunoprecipitate the antigen (bait protein) and co-immunoprecipitate any interacting proteins (prey proteins). Traditional co-IP methods that use Protein A or G result in co-elution of the antibody heavy and light chains that may co-migrate with relevant bands, masking important results. The Pierce Co-IP Kit resolves this issue by covalently coupling antibodies onto an amine-reactive resin. The kit includes optimized buffers for protein binding and recovery, reagents to perform control experiments and efficient spin columns and collection tubes, which shorten the protocol and minimize handling and mixing.
Highlights:
Works for any purified antibody – perform co-immunoprecipitation experiments using any purified antibody regardless of species or Ig class (chicken IgY, human IgE, mouse IgG1, IgM, etc.); no dependence on Protein A and Protein G affinity binding
No antibody interference – covalent attachment method and non-reducing elution system yields pure co-IP products without contamination by the IP antibody
Reusable antibody beads – covalent antibody immobilization allows prepared IP resin to be reused and provides potential savings of costly antibody
Complete Kit – all reagents for antibody immobilization and many IP experiments, including binding and wash buffers, elution buffer and convenient microcentrifuge spin columns to make resin manipulations easier and more efficient
Control beads included – underivatized agarose beads provided for use as negative control for nonspecific binding
Versatile – co-IP method is compatible with any physiolgical (non-denaturing) protein sample buffer that is compatible with the specific antibody-antigen and protein interaction complex
Includes:
AminoLink Plus Coupling Resin, coupling buffer, quenching buffer, wash solution, sodium cyanoborohydride solution, IP lysis/wash buffer, conditioning buffer, Tris-buffered saline, elution buffer, lane marker sample buffer, control agarose resin, spin columns and collection tubes
