Human IgA lambda (dimer)Catalog number: P 444
Proteins & Peptides
Purified human IgA1 lambda may be used as an IgA 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.
Chromatographically purified Human IgA1 lambda, dimer. 0.5 ml solution of 1 mg/ml P 444. No preservative added. This IgA1 consists mainly of dimers (as shown in non-reducing PAGE) and may contain traces of J chain. Confirmed by immunoelectrophoresis and double radial immunodiffusion (Ouchterlony). Not less than 98% as determined by agar-gel electrophoresis.
Concentration: 1 mg/ml
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. 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: This product is shipped at ambient temperature.
