Description:
Immunoprecipitation (IP) is a method by which a protein can be specifically purified from a complex mixture of proteins using a specific antibody and a matrix that binds the antibody. The matrix bound protein (via the specific antibody) can then be separated from the mixture by centrifugation. The matrices commonly used are agarose or sepharose bound Protein A or protein A/G PlUS. IP is one of the most widely used immunochemical techniques. IP followed by SDS-Polyacrylamide Gel Electrophoresis (SDS-PAGE) and immunoblotting is routinely used in a variety of applications: to measure the molecular weights of protein antigens, study protein/protein interactions, determine specific enzymatic activity, monitor protein post-translational modifications and determine the presence and quantity of proteins. The IP technique also enables the detection of rare proteins, which otherwise would be difficult to detect, since immunoprecipitation can concentrate them as much as 10,000-fold..
Applications:The Protein-A Immunoprecipitation Kit is especially designed to allow maximal recovery of immunoprecipitates. The whole process is performed in mini-spin columns, instead of in microcentrifuge tubes, which enables convenient washing of the antigen-antibody-bound beads.
Features:Easy access.;Minimal loss of antigen-antibody bound beads during washing.;Minimal non-specific signals by increasing the stringency of the washing steps.
Storage Condition:Stored at 4℃.and PMSF should be stored at -20℃.
