Chromatographically purified Human myeloma IgG4 kappa, allotype Gm4b.

The protein is isolated from plasma using ion exchange chromatogrpahy, affinity chromatography and gelfiltration. Identity and Purity: Confirmed by immunoelectrophoresis and double radial immunodiffusion (Ouchterlony). Not less than 98% as determined by a

Vial with 0.5mg IgG4 kappa lyophilized from 0.5ml PBS (pH 2)

This product is shipped lyophilized at ambient temperature. After arrival store at +4 degree C. Prolonged storage may be at -20 degree C. The lyophilized content is reconstituted by adding 0.5 ml of sterile distilled water, mixed gently by inversion until complete dissolution is obtained. 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. Lyophilized at +4 degree C--at least 10 years. Reconstituted at or below -20 degree C--3-5 years. Reconstituted at +4 degree C--7 days.

Purified human IgG4 kappa 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.
