| abstract |
A stable optically clear serum is prepared for use in the preparation of standards and quality control reference material for the assay of human serum components. In one aspect of the present invention, high density lipoproteins isolated from human blood serum are added to substantially human serum to produce a standard or reference material. A second aspect of the present invention involves the addition of isolated, non-primate lipoproteins to substantially human serum. The serum prepared as disclosed has good optical clarity upon lyophilization and reconstitution with aqueous media. Alternatively, the isolated lipoproteins are added in an aqueous diluent to lyophilized human serum. |
