摘要
The existence of a prohormone for relaxin has been investigated by purification from extracts of pregnant sow ovaries. Radioimmunoassay of column fractions from large scale extraction of frozen pregnant sow ovaries detected two species of high molecular weight relaxin immunoactivity besides the 6,300 dalton relaxin. On further purification, these two species were resolved into three forms with apparent molecular weights of 19,000, 13,000 and 10,000 daltons respectively. Each was biologically active and could be converted by trypsin to the 6,300 dalton relaxin. They may represent intermediates of relaxin. © 1978.
