platelet basic protein ( pbp ) , connective tissue-activating peptide iii ( ctap-iii ) , and platelet factor 4 ( pf-4 ) were purified from human platelet release supernatants by heparin-sepharose ion-exchange and reversed-phase hplc , and their neutrophil-activating effects were compared with those of nap-2 , a peptide of 70 amino acids corresponding to part of the sequence of pbp ( 1 ) and with sequence homology to naf/nap-1 .
