PROCESS FOR PREPARATION OF STORAGE STABLE HEPATITIS-FREE SERUM

摘要

Preparation of lipoprotein-free, stable and sterile serum by intimately admixing blood serum or plasma with 250 to 500 mg. colloidal silicic acid per gram of total protein and following removal of the silicic acid subjecting the serum or plasma to irradiation with ultraviolet light and sterile filtration. The separated colloidal silicic acid can be treated for elution of the adsorbed lipoproteins, the latter being suitable for use as a biochemical or immunochemical reagent.
