bioWORLDâ€šÃ Ã¶â€šÃ¢â€ s affinity-purified antibodies are of high affinity and consistently high quality. The affinity purified antibodies are tested for any 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. This chain-specific antibody allows to distinguish chains or classes of target immunoglobulins. This antibody has virtually no cross-reactivity with other immunoglobulin classes or other heavy or light chains. In conjunction with the Scorpionâ„¢ brand ofHRP detection reagents, thisBiotinylated antibody can be used for tissue and cell immunohistology, Flow cytometry, ELISAs, as well as Western blot assays. Biotinylated Goat Anti-Rat IgG (Mouse adsorbed) is supplied in solution with 0.02% azide. Can be used for flow cytometry or for tissue staining. Supplied in solution with a stabilizer and preservative.
