(A) Adhesion of the FDCP-mix cells to fibronectin, laminin-1 purified from the EHS-tumor, and human placental laminin containing the 5 chain (Laminin-10/11). The results are from four experiments performed in triplicate (Mean ± SD). The mean absorbance values at 595 nm were 0.099 to 0.264 for laminin 10/11, 0.034 to 0.133 for fibronectin, and 0.028 to 0.055 for laminin-1, each coated at 30 μg/mL, and 0.012 to 0.023 for controls. (B) Effect of MoAbs GoH3 against integrin 6 chain, and Ha2/5 and 9EG7 against integrin β1 chain on the adhesion of FDCP-mix cells to laminins containing 5 chain. (Mean ± SD, GoH3, and 9EG7, two experiments performed in triplicate; Ha2/5, two experiments with a total of nine measurements). The mean absorbance values for controls without antibodies were 0.482 and 0.081 for the two experiments.
