Anti-KLK3 antibody produced in rabbit

Prostate-specific antigen precursor recombinant protein epitope signature tag (PrEST)

Anti-KLK3 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.

Prostate-specific antigen (PSA or γ-seminoprotein or kallikrein-3 (KLK3)) is a glycoprotein enzyme encoded by the KLK3 gene in humans and belongs to tissue kallikrein family. It is an androgen-regulated serine protease produced by both prostate epithelial cells and prostate cancer cells(PCa). PSA is secreted into prostatic ducts (as an inactive 244-amino acid proenzyme (proPSA) that gets activated by cleavage of seven N-terminal amino acids). It is a major protein in semen and functions to cleave semenogelins in the seminal coagulum. PSA may have a role in pathogenesis of PCa. It acts as a useful biomarker of prostate cancer (PCa).

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
