this differential sensitivity to the toxic effect of lectin rca i was closely related to the binding of the lectin : fibroblasts from 16-day embryos had more binding sites ( 1.5 x 10 ( 7 ) /cell ) with a high affinity than did 12-day ( 0.45 x 10 ( 7 ) /cell ) or 8-day embryos ( 0.2 x 10 ( 7 ) /cell ) .
