DNA sequence analysis of V3-23 transcripts from T-cell–activated B-cell cultures.

B-cell cultures from BMT-recipient B cells supported by autologous activated T cells (sequences 1-1-1-5) and healthy-subject B cells supported by BMT-recipient T cells (sequences 4-1-4-7). Repeated isolation of the same cDNA clone is indicated by parentheses. Sequences 1-1-1-5 are taken from BMT5; sequences 4-1-4-7 are taken from HS4 (indicated by the filled circles in Figure 2).
