Anti-KLK4 Antibody

A rabbit polyclonal reagent targeting Kallikrein-Related Peptidase 4 (KLK4), distributed through Antibodies.com as a primary antibody for human research applications. KLK4 is a serine protease encoded within the tissue kallikrein gene cluster on chromosome 19q13, with documented expression in prostate epithelium, breast, ovarian, and dental enamel-forming tissues. The enzyme contributes to extracellular matrix remodeling during enamel development and has been investigated as a candidate biomarker in prostate and ovarian cancer studies.

This unconjugated antibody is raised in rabbit and is intended for Western blot and immunofluorescence workflows. In immunoblotting, the reagent is used to probe whole-cell lysates to assess KLK4 protein abundance, while immunofluorescence enables localization of KLK4 expression in fixed tissue sections or cultured cells when paired with fluorescent secondary antibodies.

The product is supplied as 100 µL of liquid, with specified reactivity toward the human target. As an unconjugated primary, it pairs readily with HRP-conjugated, biotinylated, or fluorophore-labeled secondary reagents, supporting integration into common immunodetection chemistries. Storage at -20 °C in small aliquots is recommended to preserve activity across repeated freeze-thaw cycles. For research use only; not intended for diagnostic or therapeutic use.
