Effects of recombinant Fab clones on in vitro growth of HeLa cells. Cells (1 × 104) were cultured with recombinant Fabs (A18, B3, C17) plus anti-mouse IgG F(ab')2 or with mAbs (HBJ127 and isotype-matched unrelated antibody [NC]) for 72 h at 37°C. Cell growth activity was evaluated by alamarBlue assay.
