Abstract
Colony stimulating factor derived from malignant cells has been purified by use of various techniques including multiple high performance liquid chromotography steps. By this technique, colony stimulating factor has been resolved into distinct species, and one of the species denominated as CSF-2A, has been purified to homogeneity. The high purification of the CSF-2A has enabled the amino acid composition of this protein molecule to be partially sequenced with an automated sequencer.
