This assay has high sensitivity and excellent specificity for detection of N-AChTR. No significant cross-reactivity or interference between N-AChTR and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between N-AChTR and all the analogues, therefore, cross reaction may still exist in some cases.

Store all reagents at 2-8 degree C.

Assay Type: Competitive or Sandwich. Samples: Serum, plasma, Cell Culture Supernatants, body fluid and tissue homogenate. Sensitivity: 0.1 ng/mL.

Intended Uses: This N-AChTR ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Rat N-AChTR. This ELISA kit for research use only, not for therapeutic or diagnostic applications!

Immunology

Principle of the assay: N-AChTR ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-N-AChTR antibody and an N-AChTR-HRP conjugate. The assay sample and buffer are incubated together with N-AChTR-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the N-AChTR concentration since N-AChTR from samples and N-AChTR-HRP conjugate compete for the anti-N-AChTR antibody binding site. Since the number of sites is limited, as more sites are occupied by N-AChTR from the sample, fewer sites are left to bind N-AChTR-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The N-AChTR concentration in each sample is interpolated from this standard curve.

IL27-mediated Signaling Events Pathway (137929)

The protein encoded by this gene is one of the subunits of a heterodimeric cytokine complex. This protein is related to interleukin 12A (IL12A). It interacts with Epstein-Barr virus induced gene 3 (EBI3), a protein similar to interleukin 12B (IL12B), and forms a complex that has been shown to drive rapid expansion of naive but not memory CD4(+) T cells. The complex is also found to synergize strongly with interleukin 12 to trigger interferon gamma (IFNG) production of naive CD4(+) T cells. The biological effects of this cytokine are mediated by the class I cytokine receptor (WSX1/TCRR). [provided by RefSeq, Jul 2008]

IL27-alpha: Cytokine with pro- and anti-inflammatory properties, that can regulate T-helper cell development, suppress T-cell proliferation, stimulate cytotoxic T-cell activity, induce isotype switching in B-cells, and that has diverse effects on innate immune cells. Among its target cells are CD4 T-helper cells which can differentiate in type 1 effector cells (TH1), type 2 effector cells (TH2) and IL17 producing helper T-cells (TH17). It drives rapid clonal expansion of naive but not memory CD4 T-cells. It also strongly synergizes with IL-12 to trigger interferon- gamma/IFN-gamma production of naive CD4 T-cells, binds to the cytokine receptor WSX-1/TCCR which appears to be required but not sufficient for IL-27-mediated signal transduction. IL-27 potentiate the early phase of TH1 response and suppress TH2 and TH17 differentiation. It induces the differentiation of TH1 cells via two distinct pathways, p38 MAPK/TBX21- and ICAM1/ITGAL/ERK- dependent pathways. It also induces STAT1, STAT3, STAT4 and STAT5 phosphorylation and activates TBX21/T-Bet via STAT1 with resulting IL12RB2 up-regulation, an event crucial to TH1 cell commitment. It suppresses the expression of GATA3, the inhibitor TH1 cells development. In CD8 T-cells, it activates STATs as well as GZMB. IL-27 reveals to be a potent inhibitor of TH17 cell development and of IL-17 production. Indeed IL-27 subunit p28 alone is also able to inhibit the production of IL17 by CD4 and CD8 T-cells. While IL-27 suppressed the development of proinflammatory Th17 cells via STAT1, it inhibits the development of anti-inflammatory inducible regulatory T-cells, iTreg, independently of STAT1. IL-27 has also an effect on cytokine production, it suppresses proinflammatory cytokine production such as IL2, IL4, IL5 and IL6 and activates suppressors of cytokine signaling such as SOCS1 and SOCS3. Apart from suppression of cytokine production, IL-27 also antagonizes the effects of some cytokines such as IL6 through direct effects on T-cells. Another important role of IL-27 is its antitumor activity as well as its antiangiogenic activity with activation of production of antiangiogenic chemokines such as IP- 10/CXCL10 and MIG/CXCL9. In vein endothelial cells, it induces IRF1/interferon regulatory factor 1 and increase the expression of MHC class II transactivator/CIITA with resulting up-regulation of major histocompatibility complex class II. IL-27 also demonstrates antiviral activity with inhibitory properties on HIV-1 replivation. Belongs to the IL-6 superfamily. Protein type: Secreted, signal peptide; Secreted; Cytokine. Chromosomal Location of Human Ortholog: 16p11. Cellular Component: extracellular space. Molecular Function: interleukin-27 receptor binding; cytokine activity; receptor binding. Biological Process: regulation of T-helper 1 cell differentiation; response to bacterium; regulation of T cell proliferation; regulation of defense response to virus; innate immune response; inflammatory response; positive regulation of interferon-gamma biosynthetic process
