Chemotactic activity of LD78α, intact LD78β, and LD78β(3-70) on lymphocytic and monocytic cell lines.

LD78α (♦), intact LD78β (▴), and truncated LD78β(3-70) (●) were tested at different concentrations in the in vitro Boyden microchamber chemotaxis test on (A) murine lymphocytic ESb/MP cells and (B) monocytic THP-1 cells. The results are expressed as the mean chemotactic index plus or minus SEM of 5 or more independent experiments.
