Isolation of a carp complement protein homologous to mammalian factor D.


Factor D of carp (Cyprinus carpio) complement was purified to apparent homogeneity by a 4-step chromatographic procedure and examined for physicochemical and functional properties. Carp factor D proved to be an alpha-globulin with a molecular mass of 29 kDa and the serum concentration was estimated to be 6 micrograms/ml. The NH2-terminal amino acid sequence… (More)
