In the table below, T cell proliferation was measured after 4 days of incubation of T cells, APCs, +/- SEB. If one isolated the T cells at the end of the incubation for the six conditions in which robust proliferation was seen (Rows 2, 3, 5–8), and stained the T cells with each antibody (separately) from a panel of antibodies that recognize each of the mouse Vb domains (i.e., an antibody to Vb1, an antibody to Vb2, etc), what result would be expected?
