Effects of N-(2-mercaptopropionyl) glycine on neutrophil locomotion

The effects of the sulphydryl group donor N-(2-mercaptopropionyl) glycine on neutrophil locomotion were evaluated in vitro. The drug, when used at a concentration of 10(-3) M was found to stimulate the random migration and chemotaxis of normal neutrophils as a result of an enhanced rate of locomotion. The true chemotactic response was unaffected. N-(2-mercaptopropionyl) glycine appeared to exert its effect on the whole moving cell population.
