BioWorld‚àö‚â†s affinity-purified antibodies are of high affinity and consistently high quality. The affinity purified antibodies are tested for cross-reactivities which may interfere with specific labeling and are removed by solid phase adsorption chromatography.Biotin was conjugated to these purified antibodies to ensure the maximum degree of labeling without affecting the specificity of the antibody. In conjunction with the Scorpion™ brand of Avidin: Biotin HRP reagents this antibody can be used for tissue and cell immunohistology, Flow cytometry, ELISA, as well as Western blot assays.Biotinylated Horse Anti-Mouse IgG (Rat absorbed) is supplied in solution with 0.02% azide. Can be used for flow cytometry or used for tissue staining. This rat adsorbed antibody is prepared specifically for use on tissues that may contain interfering endogenous immunoglobulins. The rat-adsorbed antibody allows primary antibodies made in mouse to be used on rat tissues. Supplied in solution with stabilizers and preservatives.
