    • A method of preparing a sterile and stable plasma-protein solution containing fibrinogen and Factor XIII from human blood plasma which has been stabilized with citrate, comprising treating the plasma with .beta.-propiolactone and irradiating it with ultraviolet light, removing the Factors II, VII, IX and X by adsorption onto anion exchangers that adsorb proteins, precipitating the companion proteins out by adding ethanol until the solution has a final concentration of about 9% by volume at -3.degree. C., centrifuging the precipitate off, dissolving the precipitate in a citrate buffer at a pH of about 6.35 and a temperature of about 37.degree. C., adjusting the protein level of the solution to about 13.3 g/l with sodium citrate solution, adding ethanol, a glycine citrate buffer, and a solution of sodium citrate to precipitate out the companion proteins, adding ethanol to the remaining solution until the solution has a final concentration of about 9% by volume at -3.degree. C., thereby precipitating fribrinogen and Factor XIII, dissolving the precipitate in a citrate buffer at a pH of about 6.35 and a temperature of about 37.degree. C., and filtering the solution.

    • A process for the fractionation of blood comprising passing said blood through a cation exchanger, separating the solids from the plasma, freezing the plasma, thawing the frozen plasma, and separating a first product comprising undissolved cryoprecipitate enriched in factor-VIII protein from plasma fluid. The cryoprecipitate can be concentrated by warm water dissolution and polyethylene glycol precipitation. The plasma fluid, optionally after treatment with .beta.-propiolactone and uv irridiation, is treated with tricalcium phosphate to adsorb factors II, VII, IX and X as a second product. These factors can be eluted with citrate solution. The residual plasma from the initial tricalcium phosphate adsorption is treated with colloidal silica to adsorb impurities and leave a third product which is a storage-stable serum protein solution.
