Background
Confirmed by immunoelectrophoresis and double radial immunodiffusion (Ouchterlony). Not less than 95% as determined by SDS-polyacrylamide gel electrophoresis, quantitative densitometry immunoelectrophoresis and double radial immunodiffusion Purified human Bence Jones kappa protein may be used as a reference antigen, calibrator, coating protein and blocking agent in a variety of immunoassays including immunodiffusion, immunoelectrophoresis, ELISA, Western blotting and dotimmunobinding assays (DIBA).

Product
Lyophilized, stable white to slightly yellowish 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.

Formulation: Lyophilized, stable white to slightly yellowish powder. No preservative added.

Specificity
Chromatographically purified Human Bence Jones kappa protein.

Storage
This product is shipped lyophilized at ambient temperature. After arrival store at +4°C. Prolonged storage may be at -20°C. Allow to stand at ambient temperature for 5-10 minutes to reach equilibrium. Reconstituted solution may be stored frozen. Working dilutions may be prepared by adding the required amount of phosphate buffered saline (PBS), should not be refrozen and preferably used within 24 hours. Repeated thawing and freezing should be avoided. If a slight precipitation occurs upon storage, this should be removed by centrifugation and will not affect the performance of the product.

Shipping Conditions: Ship at ambient temperature.
