Description

General description

Prepared by cold ethanol extraction (Cohn method) followed by crystallization.

Prepared from bovine plasma by the Cohn original cold ethanol plasma fractionation method, followed by crystallization at low temperatures. Suitable for sensitive applications requiring high albumin purity and low residual levels of globulins and other biochemical activities. Suitable for the preparation of protein and molecular weight standards, and as a blocking agent for nonspecific binding in ELISA and RIA procedures. It is also useful as an antigen carrier protein in immunological studies and monoclonal antibody production, and as a control protein for enzymatic assays, such as protease, peroxidase, phosphatase or nuclease when determining the purity of reagent grade albumins.

Preparation Note

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 6 months at -20°C.
