Neutrophil chemotactic activity of synthetic Regakine-1.

Pure natural Regakine-1 (Figure 1) was compared with chemically synthesized and purified Regakine-1, synthetic human MCP-3,16 and human IL-812 for chemotactic activity on human peripheral blood neutrophils. Results represent the mean CI (± SEM) of at least 3 independent experiments in the microchamber migration assay.
