Study on Partial Purification of the Native Human Gamma Interferon (HuIFN-?) / 中国输血杂志

ABSTRACT

A method for partially purifying the native human gamma interferon (HuIFN-?) was presented. The rude HuIFN-?was concentrated by PEG 4 000, precipitated by (NH_4)_2SO_4 and purified by CM-Sephades C-50(more than 100 times). The titre of HuIFN-?was 1.3X10~5u/ml and its specific activity was 1. 0 X 10~5u/mg protien. Quality control tests were performed and 10 volunteers received intramuscularly the purified HuIFN-?without significant changes in body temperature, pulse rate and blood pressure. It is considered to be suitable for clinical trial.
