scatchard plots on two of these clones , one epithelioid and one fibroblastic , showed that the higher egf binding ( 1.3 x 10 ( 5 ) molecules per cell for the epithelioid clone and 1.3 x 10 ( 4 ) molecules per cell for the fibroblastic clone ) was due to a greater number or receptors on the epithelioid cells rather than to a difference in the apparent affinity constant .
