Beschreibung

General description

Designed for immunoprecipitation applications. This product is blocked with BSA to reduce non-specific binding and cannot be used for purification; best for mouse IgG_2a and IgG_2b and rabbit IgG.

Protein A conjugated to agarose.

Physical form

In PBS.

Other Notes

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 IgG_2a or IgG_2b 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.
