Figure 7. Human PMN incubation with N-ac-PGP does not affect the activity of released or intracellular PE.

Freshly isolated PMNs (10⁶ cells) were stimulated for 16 hours with indicated reagents. PE activity was measured in supernatants and lysates using Z-Gly-Pro-AMC as a substrate. Control was standardized to 1. Intracellular PE activity does not change after N-ac-PGP (3·10⁻⁴–3·10⁻³ M) exposure when compared to the control (n = 3).
