Previously dialyzed Type 1 collagen was incubated with human peripheral blood neutrophils (1 × 106) with and without LPS (100μg/ml) for 1.5 hours. Supernatants were passed through a 10kDa filter and analyzed by ESI-LC-MS/MS for PGP and N-α-PGP. Levels of PGP and N-α-PGP generated are presented as mean ± SEM and compared using the two group t test. LPS-stimulated neutrophils generated significantly greater amounts of PGP and N-α-PGP (* p < 0.01 compared with collagen alone or collagen incubated with neutrophils without LPS, n = 6 per group).
