[Isoelectric variants of the principal polypeptide (p 30) of different strains of murine oncornaviruses].
The major murine oncornavirus polypeptide p 30 (30,000 daltons), which bears the conventional group-specific (gs) determinants, can be separated by isoelectric focusing into four classes, with isoelectric points (pI) of 5.5, 5.9, 6.7 and 7.1. All the Moloney stocks tested have a pI 5.9 p 30, while p 30's with three to four different pI values are found to coexist in other stocks, with the pI 6.7 form predominating in Gross virus stocks.
