Abstract
The mitogenic effect of the novel lectin prepared from an animal source on human lymphocytes was examined in comparison with that of phytohemagglutinin-p (PHA-p) by the uptake of 3H-thymidine. The uptake of 3H-thymidine by lympho-blasts was enhanced by the treatment with the lectin as well as with PHA-p, though the effect of the lectin was difficult to compare exactly with that of PHA-p.
