Chemotactic activity of LD78α, intact LD78β, and LD78β(3-70) on human lymphocytes.

LD78α (♦), intact LD78β (▴), and truncated LD78β(3-70) (●) were tested at different concentrations in the in vitro Boyden microchamber chemotaxis test on freshly isolated peripheral blood–derived human lymphocytes. The results are expressed as the mean chemotactic index plus or minus SEM of 4 or more independent experiments.
