Human Kallikrein 3 / KLK-3 Protein

  • Synonym
    KLK3,Kallikrein-3,APS,KLK2A1,PSA,Hk3,Seminin,Semenogelase
  • Source
    Human Kallikrein 3, His Tag (KL3-H5226) is expressed from human 293 cells (HEK293). It contains AA Ala 18 - Pro 261 (Accession # NP_001639).
    Predicted N-terminus: Ala 18
  • Molecular Characterization
    Online(Ala 18 - Pro 261) NP_001639

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

    The protein has a calculated MW of 27.7 kDa. The protein migrates as 30-33 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

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

    >92% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

    No activity loss was observed after storage at:

    1. 4-8°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
