IgG1,IgG1 lamda G1m(f) from Human-unconj.

Confirmed by immunoelectrophoresis and double radial immunodiffusion (Ouchterlony). Not less than 98% as determined by agar-gel electrophoresis, quantitative densitometry immunoelectrophoresis and double radial immunodiffusion (Ouchterlony). Purified human IgG1 lambda may be used as a reference antigen, calibrator, coating protein and blocking agent in a variety of immunoassays including immunodiffusion, immunoelectrophoresis, ELISA, Western blotting, dot-immunobinding assays (DIBA), haemagglutination, and cell-binding assays.

Lyophilized, stable white powder. No preservative added The lyophilized content is reconstituted by adding 0.5 ml of sterile distilled water, mixed gently by inversion until complete dissolution is obtained.
