INJECTABLE SOLUTION OF A RECOMBINANT INTERLEUKIN-2 OR INTERFERON-BETA PURIFIED PROTEIN

摘要

A pharmaceutical composition containing IL-2 or IFN- beta dissolved in a suitable carrier medium at pH 7.0 to 8.0 stabilized with sodium laurate is suitable for parenteral injection into humans or animals. This formulation may be prepared by adding to either protein, after its recovery from a transformed organism, an effective amount of sodium laurate at a pH of 9 to 9.5 and then adjusting the pH of the formulation to between 7.0 and 8.0.
