FIELD: medicine, hematology. SUBSTANCE: method involves gelatin dissolving in water, its thermic destruction in an aqueous solution and deionization on ion-exchange resins, gelatin hydrolysis, addition of sodium hydrogen hydrocitrate, solution neutralization, addition of sodium chloride and sterilizing filtration. Before neutralization the sterilized aqueous solution of adenine (final concentration is 0.30-0.45 g/l) and sodium hydrogen phosphate (3.5-4.5 g/l) were added to solution additionally at 50-60 C. Gelatin deionization is carried out on cation-exchange resins. EFFECT: improved method of preparing. |
