FIG. 4.
Immunoblot analysis of the hamster Brca2 protein in V-C8 and V79 cells with antibody pep-4 raised against the 13 most carboxy-terminal amino acids of the mouse Brca2 protein (a) and the human BRCA2 protein in V-C8+#13 microcell hybrids with antibody Ab-1, raised against amino acids 1651 to 1821 of human BRCA2 (b). The wild-type simian virus 40-transformed human fibroblast cell line MRC5V1 was used as a positive control.
