Normal human peripheral lymphocytes, cultured in serum-deprived medium, synthetized and released serum albumin and some glycoproteins into the culture supernatant. With the use of [3H]leucine, it was shown that this biosynthetic activity was increased about 2-3 times when the mitogenic lectin from Robinia pseudo acacia was added to the lymphocyte culture medium.
