other studies demonstrated that ( a ) on average , antibody-secreting clones were generated more slowly when b cells from anti-delta antibody-treated mice were used as a source of precursors than b cells of control mice and ( b ) both sig- spleen cells and sig+ spleen cells from anti-delta antibody-treated mice generated a higher frequency of specific antibody-secreting clones than did the corresponding populations from control mice .
