A STUDY ON THE WATER—SOLUBLE PEPTIDES IN RAPE POLLEN:EXTRACTION,PURIFICATION,SEQUENCE DETERMINATION AND MEASUREMENT OF IMMUNOPROMOTIVE ACTIVITY

摘要

Four peptide components RP1,RP2,RP3Ⅰ and RP3Ⅱ were purified from the water—ex-tract of rape(Brassica campestris L.)pollen.The primary sequence of RP3I,with 12 amino acidresidues,has been determined by Edman degradation—N—terminal dansylation.The immunopro-motive activities of the initially separated sample and RP3I have been also observed in vitro.
