Activity and storage stability of proteins in a hepatitis-free human serum preparation

The activity of certain selected serum proteins was investigated in Biseko, a product prepared from beta-propiolactone/UV treated, pooled human plasma. It was shown that the biological activity of the immunoglobulins, transport proteins and inhibitor proteins was not affected by the manufacturing process. With the exception of alpha 1-antitrypsin and coeruloplasmin, the biological activity of the proteins studied proved to be preserved on storage at 37 degrees C.
