Elafin/PI3 BioAssay(TM) ELISA Kit, Human

Sandwich ELISA quantitative detection kit for Human Elafin/PI3 in cell culture supernates, cell lysates, serum and plasma (heparin, EDTA). Elafin, also known as peptidase inhibitor 3 or skin-derived antileukoproteinase (SKALP) is a protein that in humans is encoded by the PI3 gene. It is mapped to 20q13.12. This gene encodes an elastase-specific inhibitor that functions as an antimicrobial peptide against Gram-positive and Gram-negative bacteria. The protein contains a WAP-type four-disulfide core (WFDC) domain, and is thus a member of the WFDC domain family. Most WFDC gene members are localized to chromosome 20q12-q13 in two clusters: centromeric and telomeric. This gene belongs to the centromeric cluster. Expression of this gene is upgulated by bacterial lipopolysaccharides and cytokines. This gene is the neutrophil and pancreatic elastase-specific inhibitor of skin. It may prevent elastase-mediated tissue proteolysis. , Assay Range:, 31.2-2000pg/ml, Sensitivity: <10pg/ml, Uniprot ID: P19957, Entrez Gene ID: 5266, Specificity: Natural and recombinant human Elafin/PI3.
