  • Source
    Human HE4, His Tag (HE4-H5223) is expressed from human 293 cells (HEK293). It contains AA Glu 31 - Phe 124 (Accession # AAH46106).
    Predicted N-terminus: Glu 31
  • Molecular Characterization
    Online(Glu 31 - Phe 124) AAH46106

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 10.9 kDa. The protein migrates as 19-23 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

  • Background
    Human Epididymis Protein 4 (HE4) is also known as WAP four-disulfide core domain protein 2 (WFDC2), Epididymal secretory protein E4, Major epididymis-specific protein E4, Putative protease inhibitor WAP5, is a member of the WFDC domain family. HE4 / WFDC2 is expressed in pulmonary epithelial cells, and was also found to be expressed in some ovarian cancers. The WFDC domain, or WAP Signature motif, contains eight cysteines forming four disulfide bonds at the core of the protein, and functions as a protease inhibitor in many family members. HE4 is also a small secretory protein, which may be involved in sperm maturation.
