title: Surface antigen expressed in hematopoietic cells derived from Fv-4r mouse strains.
abstract: Fv-4 locus controls the susceptibility of mice to ecotropic murine leukemia virus (MuLV). Antiserum against Fv-4r/s mice with BALB/c background was raised in inbred BALB/c mice. In the complement-dependent cytotoxicity test, the antiserum killed the hematopoietic cells derived from Fv-4r/- mice but not these from Fv-4s/s mice,  and the genetic cross experiments located the locus controlling the expression of the target molecule of the antibody in the close vicinity of Fv-4. In addition, the antigenic expression of the exogenously infecting MuLV suppressed the expression of the target molecule of the antiserum. The expressions of these two antigens appear to compete with each other on the cell surface.
