| abstract |
The invention provides processes for producing preparations (e.g., plasma preparations or fibrinogen (Fg)-depleted preparations) containing one or more proteins (e.g., plasma proteins). Processes of the invention can be used to obtain enriched preparations of one or more proteins (e.g., Fg, immunoglobulin (Ig; e.g., IgG), alpha-1 proteinase inhibitor (A1 PI), albumin, plasminogen, prothrombin complex, and/or other plasma proteins). Multiple enriched preparations can be obtained from a single sample (e.g., a whole blood or plasma sample) using the processes of the invention. |
