SDS-PAGE shows one band only, corresponding to a molecular weight of approx. Supplied lyophilised from 0.02M NH4HCO3. May contain traces of buffer salts. The use of a buffered solution containing physiological levels of saline may aid complete dispersion of the product upon reconstitution. Purified to a level where no contaminating proteins can be detected using a range of analytical techniques.
Cellulose acetate electrophoresis shows one band only, indicating Alpha electrophoretic mobility.
SDS-PAGE shows one band only, corresponding to a molecular weight of approx. IgM to be undetectable.
