A member of the integrin family, the alpha 6 beta 4 complex was previously identified on human and mouse carcinoma cell lines by using a rat monoclonal antibody to alpha 6. Here we describe two monoclonal antibodies that recognize epitopes on the beta 4 subunit of the human and mouse alpha 6 beta 4 complexes. The monoclonal antibodies against beta 4 were(More)
Electron microscopy, immunofluorescence, and bioassay demonstrated the presence of a mammary tumor inciting virus in untreated mice of three different inbred strains, and in irradiated or urethan-treated mice of two other mouse strains, indicating the ubiquitous nature of this group of viruses. In general these viruses are transmitted vertically by the(More)
