SERPINA4 ELISA 试剂盒

Synonyms: KAIN_HUMAN, Kallikrein inhibitor, Kallistatin, Peptidase inhibitor 4, PI-4, PI4, Serpin A4, SERPINA4

Background: Serpin peptidase inhibitor, clade A(alpha-1 antiproteinase, antitrypsin), member 4, also called Kallistatin, is a protein that in humans is encoded by the SERPINA4 gene. This gene is mapped to chromosome 14q32.13. Kallistatin is a serine proteinase inhibitor(serpin) and a heparin-binding protein. It is localized in vascular smooth muscle cells and endothelial cells of blood vessels, suggesting that it may be involved in the regulation of vascular function. It shows that kallistatin plays a role in neointima hyperplasia. The potential role of kallistatin was investigated in angiogenesis in vitro and in vivo, and presented results demonstrating a novel role of the protein in the inhibition of angiogenesis and tumor growth.

Gene Name: SERPINA4

Production: Natural and recombinant human Kallistatin. There is no detectable cross-reactivity with other relevant proteins.

Standard: Expression system for standard: NSO, Immunogen sequence: Q21-P427

Application Note: Useful in Sandwich ELISA for Quantitative Detection of Antigen. Aliquot 0.1 mL per well of the 10000pg/mL, 5000pg/mL, 2500pg/mL, 1250pg/mL, 625pg/mL, 312pg/mL, 156pg/mL human Kallistatin standard solutions into the precoated 96-well plate. Add 0.1 mL of the sample diluent buffer into the control well (Zero well). Add 0.1 mL of each properly diluted sample of human cell culture supernates, serum or plasma(heparin, EDTA) to each empty well. It is recommended that each human Kallistatin standard solution and each sample be measured in duplicate.
