Abstract
A protein effective in stimulating cell growth activity. The protein has a molecular weight of from 5,000 to about 160,000, is composed predominantly of neutral and acidic amino acids, contains a significant amount of glutamic acid and aspartic acid, and is substantially free of nucleoside phosphotransferase. The protein is useful as wound treatment agent and as promoting agent in the synthesis of DNA. A method of producing the protein and compositions containing the same are also disclosed.
