  1. aSum of all discrete bands across the immunoblots of all four MMTV strains (RIII, FM, C3H, and LA). As shown in Figure 1A, serum from Patient #16 had eight bands (1 against RIII, 2 against FM, 2 against C3H, and 3 against LA), and sera from Patients #36 and 60 had six bands (two each of the same molecular weight against RIII, FM, and LA).
