  • Synonym
    KLK2A2, hGK-1, hK2
  • Source
    Human Kallikrein 2 Protein, Tag Free(KA2-H5214) is expressed from human 293 cells (HEK293). It contains AA Ile 25 - Pro 261 (Accession # P20151-1).
    Predicted N-terminus: Ile 25
  • Molecular Characterization
    Kallikrein 2 Structure

    This protein carries no "tag".

    The protein has a calculated MW of 26.2 kDa. The protein migrates as 30-31 kDa when calibrated against Star Ribbon Pre-stained Protein Marker 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

    Supplied as 0.2 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5 with glycerol as protectant.

SDS-PAGE
Kallikrein 2 SDS-PAGE

Human Kallikrein 2 Protein, Tag Free on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).

Bioactivity

Measured by its ability to cleave a flourogenic peptide substrate Pro-Phe-Arg-7-amido-4-methylcoumarin (PFR-AMC). The specific activity is >350 pmol/min/µg (QC tested).

  • Background
    This gene encodes a member of the grandular kallikrein protein family. Kallikreins are a subgroup of serine proteases that are clustered on chromosome 19. Members of this family are involved in a diverse array of biological functions. The protein encoded by this gene is a highly active trypsin-like serine protease that selectively cleaves at arginine residues. This protein is primarily expressed in prostatic tissue and is responsible for cleaving pro-prostate-specific antigen into its enzymatically active form. This gene is highly expressed in prostate tumor cells and may be a prognostic maker for prostate cancer risk. Alternate splicing results in both coding and non-coding transcript variants.
