| Notch proteins are single-pass transmembrane receptors that regulate cell fate decisions during development. The Notch family includes 4 receptors, NOTCH1, NOTCH2, NOTCH3, and NOTCH4, whose ligands include JAG1, JAG2, DLL1), DLL3, and DLL4. Notch homolog 1, translocation-associated (NOTCH1), is a human gene encoding a single-pass transmembrane receptor. It functions as a receptor for membrane bound ligands, and may play multiple roles during development. NOTCH1 may normally coordinates the process of somitogenesis, and the activated Notch 1 and Notch 3 promote differentiation of progenitor cells into astroglia. Sample Type: Cell culture supernates, serum, plasma (Heparin or EDTA). Intended Use: Sandwich High Sensitivity BioAssay(TM) ELISA kit for Quantitative Detection of Human NOTCH1. Sensitivity: <12pg/ml Range: 62.5pg/ml-4000pg/ml Specificity: Recognizes natural and recombinant Human NOTCH1. There is no detectable cross-reactivity with other relevant proteins. Test Principle: This Human NOTCH1 BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A a monoclonal antibody from mouse specific for NOTCH1 has been precoated onto 96-well plates. Standards(Expression system for standard: NSO, Immunogen sequence: A19-Q526) and test samples are added to the wells, a biotinylated detection a biotinylated polyclonal antibody from goat specific for NOTCH1 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 NOTCH1 amount of sample captured in plate. Kit Components: 96-well plate precoated with anti-Human NOTCH1 antibody, 1x plate Lyophilized recombinant Human NOTCH1 standard, 2x10ng/tube Biotinylated anti-Human NOTCH1 antibody, 1x130ul (dilution 1:100) Avidin-Biotin-Peroxidase Complex (ABC), 1x130ul (dilution 1:100) Sample diluent buffer, 1x30ml Antibody diluent buffer, 1x12ml ABC diluent buffer, 1x12ml TMB color developing agent, 1x10ml TMB stop solution, 1x10ml PBS washing buffer Powder for 1000ml, 1x buffer Storage and Stability: Store powder at 4C liquid at -20C. Store other components at 4C. Stable for at least 6 months For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. |
