S100 calcium-binding protein A12 (S100A12) is a protein that in humans is encoded by the S100A12 gene. It is also known as calgranulin C. By direct R-banding FISH, the S100A12 gene is mapped to chromosome 1q21.2-q22. The protein encoded by this gene is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are 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. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21. And this protein is proposed to be involved in specific calcium-dependent signal transduction pathways and its regulatory effect on cytoskeletal components may modulate various neutrophil activities.
Sample Type:Cell culture supernates, serum and plasma (heparin, EDTA)
Intended Use:For quantitative detection of human S100A12 in cell culture supernates, serum and plasma( heparin, EDTA).
Sensitivity:<10pg/ml
Range:312-20,000pg/ml
Specificity:Natural and recombinant human S100A12
Test Principle:This human S100A12 BioAssay™ ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for S100A12 has been precoated onto 96-well plates. Standards(E.coli) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for S100A12 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human S100A12 amount of sample captured in plate.
