Detection of Matriptase/ST14 in PC‑3 Human Cell Line by Flow Cytometry. PC‑3 human prostate cancer cell line was stained with Sheep Anti-Human Matriptase/ST14 Catalytic Domain Biotinylated Antigen Affinity‑purified Polyclonal Antibody (Catalog # BAF3946, filled histogram) or isotype control antibody ???, followed by Streptavidin-Phycoerythrin (Catalog # F0040). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.

Human matriptase, encoded by the ST14 (suppression of tumorogenicity 14) gene, is also known as tumor associated differentially expressed gene 15 protein/TADG-15), epithin, and membrane-type serine protease 1/MT-SP1. Predicted to have a significant role in tumor biology, matriptase may be a novel target for anti-cancer therapy. However, expressed in most human epithelia, matriptase is also important in several physiological processes. For example, it activates prostasin to initiate a protease cascade that is essential for epidermal differentiation, and it converts a single-chain IGFBP-rp1 into the two-chain form.
