Abstract
The invention involves the purification of various glial mitogenic factors. In one aspect of the invention, vertebrate brain material is extracted, and the extract is then subjected to chromatographic separation. The glial mitogenic factors which can be obtained include a basic polypeptide with a molecular weight of from about 30 to about 36 kD, by reference to SDS-PAGE, and a second basic polypeptide factor which is from about 55 to about 63 kD as determined by SDS-page.
