Custom Premix Selecting "Custom Premix" option means that all of the beads you have chosen will be premixed in manufacturing before the kit is sent to you.
Designed for immunoprecipitation applications. This product is blocked with BSA to reduce non-specific binding and cannot be used for purification; best for mouse IgG2a and IgG2b and rabbit IgG.

Immunoprecipitation
Application Comments
Agarose solutions are supplied ready-to-use for immunoprecipitation. Use 15 µl suspension/µg primary antibody. Protein A-Agarose is recommended for use in immunoprecipitation assays using rabbit polyclonal antibodies or unmodified mouse IgG2a or IgG2b monoclonal antibodies. Mouse IgG1 or IgG3 and all rat antibodies bind poorly to Protein A. As an alternative, use Protein G PLUS, Protein G PLUS/Protein A, or rabbit second-step antibodies to bridge these antibodies to Protein A. Preclearing will minimize extra bands resulting from nonspecific precipitation. To preclear, add to the sample 20 µl of agarose conjugate and 1 µg of normal IgG from the same species as the immunoprecipitating antibody. When immunoblotting is used for detection, some secondary antibodies can react nonspecifically with BSA or other proteins present at high concentrations in the sample. This can be eliminated by reducing the concentration of secondary antibody.
