Product Overview
This rabbit polyclonal antibody targets WAP four-disulfide core domain protein 2 (gene Wfdc2) in rat samples and is validated for ELISA. The predicted molecular weight is 17.4 kDa.
WFDC2, better known as HE4 (human epididymis protein 4), is a small secreted protein carrying WAP four-disulfide core domains of the type found in protease inhibitors. It is expressed in epithelia of the reproductive tract and airways, animal studies show it is needed for normal lung and airway epithelial development, and serum HE4 is widely measured in ovarian cancer research.
