Immunoprecipitation (IP)

What is Immunoprecipitation? Immunoprecipitation (IP) is a technique used to isolate and purify proteins from a sample. It is based on the principle of affinity between an antibody and its antigen. The antigen-antibody complex is then precipitated. This technique is widely used in the study of protein-protein interactions, protein-DNA interactions, and post-translational modifications. How Does Immunoprecipitation Work? Immunoprecipitation begins with the addition of a specific antibody to the sample. The antibody binds to its antigen, forming an antigen-antibody complex. The antigen-antibody complex is then precipitated out of solution using a reagent such as agarose. The precipitated complex can then be collected, separated, and analyzed. How to choose the Right Antibody for Immunoprecipitation? When choosing an antibody for immunoprecipitation, it is important to consider the specificity and affinity of the antibody. Specificity refers to the ability of the antibody to recognize and bind to its antigen. Affinity refers to the strength of the binding between the antibody and its antigen. High specificity and affinity are important for successful immunoprecipitation. ProteoGenix Antibodies for Immunoprecipitation ProteoGenix offers a wide range of antibodies for immunoprecipitation. Our antibodies are highly specific and have high affinity for their antigens. They also offer a wide range of species-specific antibodies, making it easy to find the right antibody for your experiment.
