Control Antibodies

These IgG preparations are intended for use as controls for primary antibodies made in rabbit, mouse, rat, and goat. Supplied as lyophilized powders, these antibodies have been purified from pooled serum of healthy adult animals and contain a spectrum of the IgG subclasses present in serum. They should be applied to a control tissue section at the same concentrations as the primary antibody to indicate whether staining is specific for the antigen or is non-specific adsorption of primary antibody to tissue sites.
