Viral and cellular surface antigens of murine leukemias and myelomas. Serological analysis by immunoelectron microscopy
Abstract
IMMUNOELECTRON MICROSCOPY (IEM) OF MOUSE CELLS WHICH WERE PRODUCTIVELY INFECTED WITH MURINE LEUKEMIA VIRUS (MULV) YIELDED THE FOLLOWING CONCLUSIONS: See PDF for Structure With two exceptions, the alloantigens H-2, theta, Ly-A, and Ly-B were not present on complete or incomplete virions produced by cells bearing these antigens.The exceptions were H-2(k) (but not H-2(b)) and theta both appeared on only a minority of virions and never on more than a small part of the circumference. The incidental discovery of an additional envelope antigen on virions produced by a BALB/c mouse myeloma but lacking from passage A Gross virions distinguishes these two viruses as MuLV subtypes; it also illustrates that IEM can be applied as a primary tool for antigenic analysis, as well as for its usual purpose of finding out where antigens are situated.
