Nori Feline S100A12 ELISA Kit
$461.00 – $832.00
This ELISA kit is for quantification of S100A12 in cat. This is a quick ELISA assay that reduces time to 50% compared to the conventional method, and the entire assay only takes 3 hours. This assay employs the quantitative sandwich enzyme immunoassay technique and uses biotin-streptavidin chemistry to improve the performance of the assays. An antibody specific for S100A12 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any S100A12 present is bound by the immobilized antibody. After washing away any unbound substances, a detection antibody specific for S100A12 is added to the wells. Following wash to remove any unbound antibody reagent, a detection reagent is added. After intensive wash a substrate solution is added to the wells and color develops in proportion to the amount of S100A12 bound in the initial step. The color development is stopped, and the intensity of the color is measured.

Background:
S100 calcium-binding protein A12 (S100A12) is a protein that in humans is encoded by the S100A12 gene.[1] It is also known as calgranulin C and belong to the S100 protein family containing 2 EF-hand calcium-binding motifs that is a novel group of proinflammatory molecules.[2] like other S100 proteins, S100A12 is localized in the cytoplasm and/or nucleus of a wide range of cells and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100A12 is a novel antimicrobial peptide [3] and is proposed to be involved in specific calcium-dependent signal transduction pathways and its regulatory effect on cytoskeletal components may modulate various neutrophil activities. CacyBP/SIP, a calcyclin and Siah-1-interacting protein, binds EF-hand proteins of the S100 family like S100A2.[4] “Neutrophil derived human S100A12 (EN-RAGE) is strongly expressed during chronic active inflammatory bowel disease.[5] S100A12 can be used as a biomarker in monitoring Kawasaki disease.[6]
