Purification and primary structures of duck fibrinopeptides A and B
Abstract:
Duck fibrinopeptides A and B were purified by Dowex 50 W X 2 ion exchange resin and DEAE-Sepharose CL-6B. The complete primary structures of duck fibrinopeptides A and B were determined by manual Edman Sequence determination. The primary structure of duck fibrinopeptide A is pyr. Asp. Gly. Lys. Ser. Ser. Phe. Gln. Lys. Glu. Gly. Gly. Gly. Val. Arg., and that of duck fibrinopeptide B is Pyr. Ala. Ser. Thr. Asp. Tyr. Asp. Asp. Glu. Asp. Glu. Ser. Thr. Val. Pro. Glu. Ala. Arg.
