Fig. 8. Colorimetric BrdU cell proliferation ELISA of human corneal epithelial cells cultured under normoxic (20% O2) conditions in the presence of function-blocking antibody to laminin 5 (P3H9-2) or control IgG. Proliferation is represented as the mean absorbance (A450) in arbitrary units + s.e.m. (n=30 for each culture treatment). Proliferation is significantly lower (*, P=0.0004) in normoxic cells treated with laminin 5 antibody compared with control IgG.
