Control Antibodies

These IgG preparations (I-1000, I-2000, I-4000, and I-5000) are intended for use as controls for primary antibodies made in rabbit, mouse, rat, or 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 the control tissue section at the same concentrations as the primary antibody. These control sections will help determine whether staining with the primary antibody is specific for the antigen or whether staining is the result of nonspecific adsorption of primary antibody to tissue sites.
