Kallikrein-12 is a protein that in humans is encoded by the KLK12 gene. It belongs to the kallikrein subgroup of serine proteases, which have diverse physiologic functions in many tissues. KLK12 is expressed primarily in salivary gland, stomach, uterus, trachea, prostate, thymus, lung, colon, brain, breast, and thyroid gland and at lower levels in testis, pancreas, small intestine, and spinal cord. The expression of KLK12 is downregulated at the mRNA level in breast cancer tissues and is upregulated by steroid hormones in breast and prostate cancer cell lines. Sample Type: Cell culture supernates, serum and plasma (heparin, EDTA) Intended Use: For quantitative detection of human KLK12 in cell culture supernates, cell lysates, tissue homogenates, serum and plasma (heparin, EDTA). Sensitivity: <10pg/ml Range: 156-10,000pg/ml Specificity: Natural and recombinant human KLK12 Test Principle: This human KLK12 BioAssay? ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent ass
