Abstract

A broad-spectrum antiserum has been obtained against nuclear proteins from normal mouse fibroblasts. Solid phase immunoadsorbants prepared from the serum specifically bind the corresponding antigens. The removal in this way of a significant fraction of host proteins leads to partial purification of viral and virus-induced polypeptides from polyoma virus-infected cell extracts. Four main peptides can be selected, with respective molecular weights of 90,000, 70,000, 46,000, and 41,000.
