A human lymphocyte mitogen extracted from the extracellular slime layer of Pseudomonas aeruginosa

Slime glycolipoprotein of Pseudomonas aeruginosa has been found to exert a mitogenic effect on human peripheral blood and cord blood lymphocytes. The optimal concentration of glycolipoprotein was shown to be in the range of 100--200 micrograms/ml, and maximal incorporation of [14C]thymidine was seen on the fourth day of lymphocyte cultures.
