Human epididymal protein 4 antibody（HE4)

Human epididymal protein 4 (HE4), first discovered in the epithelial cells of the distal epididymis, is a new tumor marker of ovarian cancer. It consists of two core structures: a natural N-terminal glycosylated protein of about 25kDa and two whey acidic protein core regions (WAP, consisting of four disulfide bond core regions and eight cysteine residues).
