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. SDS-PAGE confirms AGP as the major component with molecular weight of approx.
Albumin is present as the main contaminant.
