Store all reagents at 2-8 degree C

Samples: Serum, Plasma, Tissue Homogenate, Feces, Urine and Body Fluids. Assay Type: Sandwich. Detection Range: 125 pg/ml - 4000 pg/ml. Sensitivity: 10 pg/ml.

Intended Uses: This Quantitative Sandwich ELISA kit is only for in vitro research use only, not for drug, household, therapeutic or diagnostic applications! It is intended to be determinated S100A8 concentrations in Rat serum, plasma and other body fluids. Using Purified Rat S100A8 antibody to coat Microelisa Stripplate wells to make solid-phase antibody, then add S100A8 and S100A8 antibody which has been labeled with HRP to wells, then the reactants become antibody-antigen-antibody-enzyme complex, after washing completely, add TMB substrate solution, TMB substrate becomes blue color under HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of S100A8 in the samples is then determined by comparing the O.D. of the samples to the standard curve. Intra-assay Precision: Intra-assay CV (%) is less than 15%. Inter-assay Precision: Inter-assay CV (%) is less than 15%. [CV(%) = SD/mean ×100]

S100A8: S100A8 is a calcium- and zinc-binding protein which plays a prominent role in the regulation of inflammatory processes and immune response. It can induce neutrophil chemotaxis and adhesion. Predominantly found as calprotectin (S100A8/A9) which has a wide plethora of intra- and extracellular functions. The intracellular functions include: facilitating leukocyte arachidonic acid trafficking and metabolism, modulation of the tubulin-dependent cytoskeleton during migration of phagocytes and activation of the neutrophilic NADPH-oxidase. Activates NADPH- oxidase by facilitating the enzyme complex assembly at the cell membrane, transfering arachidonic acid, an essential cofactor, to the enzyme complex and S100A8 contributes to the enzyme assembly by directly binding to NCF2/P67PHOX. The extracellular functions involve proinfammatory, antimicrobial, oxidant-scavenging and apoptosis-inducing activities. Its proinflammatory activity includes recruitment of leukocytes, promotion of cytokine and chemokine production, and regulation of leukocyte adhesion and migration. Acts as an alarmin or a danger associated molecular pattern (DAMP) molecule and stimulates innate immune cells via binding to pattern recognition receptors such as Toll-like receptor 4 (TLR4) and receptor for advanced glycation endproducts (AGER). Binding to TLR4 and AGER activates the MAP-kinase and NF- kappa-B signaling pathways resulting in the amplification of the proinflammatory cascade. Has antimicrobial activity towards bacteria and fungi and exerts its antimicrobial activity probably via chelation of Zn(2+) which is essential for microbial growth. Can induce cell death via autophagy and apoptosis and this occurs through the cross-talk of mitochondria and lysosomes via reactive oxygen species (ROS) and the process involves BNIP3. Can regulate neutrophil number and apoptosis by an anti-apoptotic effect; regulates cell survival via ITGAM/ITGB and TLR4 and a signaling mechanism involving MEK-ERK. Its role as an oxidant scavenger has a protective role in preventing exaggerated tissue damage by scavenging oxidants. Can act as a potent amplifier of inflammation in autoimmunity as well as in cancer development and tumor spread. Belongs to the S-100 family. Chromosomal Location of Human Ortholog: 1q21. Cellular Component: extracellular space; cytoskeleton; extracellular region; plasma membrane; cytosol; nucleus. Molecular Function: arachidonic acid binding; protein binding; RAGE receptor binding; zinc ion binding; microtubule binding; calcium ion binding. Biological Process: caspase activation; neutrophil chemotaxis; chronic inflammatory response; chemokine production; wound healing; cytokine production; positive regulation of peptide secretion; response to lipopolysaccharide; positive regulation of cell growth; leukocyte migration during inflammatory response; activation of NF-kappaB transcription factor; sequestering of zinc ion; response to ethanol; response to zinc ion; defense response to bacterium; innate immune response; autophagy; inflammatory response; defense response to fungus; acute inflammatory response; regulation of cytoskeleton organization and biogenesis; positive regulation of inflammatory response
