Description_x000D_ Specificity_x000D_ This product was prepared from monospecific antiserum by immunoaffinity chromatography using antigens coupled to agarose beads followed by solid phase adsorption(s) to remove any unwanted reactivities. Assay by immunoelectrophoresis resulted in a single precipitin arc against Anti-Goat Serum, Rat IgM and Rat Serum. No reaction was observed against Rat IgG or Rat IgA. Specificity was confirmed by ELISA at less than 1% cross reactivity against other Rat heavy or light chain isotypes._x000D_ Immunogen_x000D_ Rat IgM mu heavy chain_x000D_ Physical form_x000D_ Supplied in 0.02 M Potassium Phosphate, 0.15 M Sodium Chloride, pH 7.2 with 10 mg/mL Bovine Serum Albumin (BSA) - Immunoglobulin and Protease free_x000D_ Reconstitution_x000D_ Reconstitute with 1.0 mL deionized water (or equivalent)._x000D_ Physical properties_x000D_ Antibody format: IgG
