When separated by 2-dimensional gel electrophoresis, the 22 and 19 kD components each resolve into a number of charged isomers, but the proteins of 27, 15, 14, and 10 kD migrate as single polypeptides. Based on immunocytochemical analysis, the 22 and 19 kD proteins are distributed throughout t

Other approaches have depended on enrichment of mRNA encoding the receptor; the low density lipoprotein receptor (6) and the T cell receptor (7) genes have been isolated by such means. We have employed an alternative approach which relies on DNA mediated

This technique, though powerful, has the limitation of requiring antibodies, which usually necessitates prior purification of a specific protein of interest. An alternative approach is to detect isoproteins in a gel by their biochemical activities. Ou

Many of the mild virus strains used are generated by nitrous acid mutation of the virulent strain. Alternately, a va
