Abstract/OtherAbstract:
A neutrophil chemotactic factor (NCF-Di) was purified from a crude extract of Dirofilaria immitis adult worm by a combination of anion-exchange chromatography on DE52 and gel filtration on Sephacryl S-200. NCF-Di showed a single protein band by both polyacrylamide gel electrophoresis (PAGE) and sodium dodecyl sulfate (SDS) PAGE. The molecular weight of NCF-Di was estimated to be 17,000 by gel filtration on Sephadex G-150, and 14,000 by SDS-PAGE. NCF-Di was an acidic protein with isoelectric point of 4.5. NCF-Di was absorbed neither to lentil lectin-Sepharose nor to concanavalin A-Sepharose. The chemotactic activity of NCF-Di was heat labile (56 C, 1 hr), but was resistant to periodate oxidation. These results suggest that NCF-Di is a simple peptide which has few or no sugar chains. These physicochemical properties of NCF-Di were compared to previously reported parasite-derived chemoattractants or purified allergen of D. immitis.
