Immunoprecipitation makes use of antibodies that specifically bind and precipitate protein antigens out of solution. This process can be used to isolate and concentrate a particular protein from a cell lysate. Immunoprecipitation requires that the antibody be coupled to a solid substrate such as magnetic particles or agarose resin. The precipitated protein can then be detected via Western blot. Bio X Cell offers many antibodies that are reported for use in immunoprecipitation. For protocol details such as antibody concentration and secondary antibody selection we have compiled an up-to-date list of references for each antibody. These can be found on the individual product pages.
