Insulin-like growth factor 2 receptor, also called IGF2R or I-MPR is a protein that in humans is encoded by the IGF2R gene. This gene is mapped to 6q25.3. This gene encodes a receptor for both insulin-like growth factor 2 and mannose 6-phosphate, although the binding sites for either are located on different segments of the receptor. This receptor functions in the intracellular trafficking of lysosomal enzymes, the activation of transforming growth factor beta, and the degradation of insulin-like growth factor 2. While the related mouse gene shows exclusive expression from the maternal allele, imprinting of the human gene appears to be polymorphic, with only a minority of individuals showing expression from the maternal allele. Sample Type: Cell culture supernates, serum and plasma (heparin, EDTA) Intended Use: For quantitative detection of human IGF2R in cell culture supernates, serum and plasma (heparin, EDTA). Sensitivity: <10pg/ml Range: 156-10,000pg/ml Specificity: Natural and recombinant human IGF2R Test Principle: This human IGF2R BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for IGF2R has been precoated onto 96-well plates. Standards(NSO, S1510-F2108) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for IGF2R 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 IGF2R amount of sample captured in plate. Kit Components: 96-well plate precoated with human IGF2R antibody, 1 Lyophilized recombinant human IGF2R standard, 10ng/tube*2 Biotinylated human IGF2R antibody, 130ul (dilution 1:100) Avidin-Biotin-Peroxidase Complex (ABC), 130ul (dilution 1:100) Sample diluent buffer, 30ml Antibody diluent buffer, 12ml ABC diluent buffer, 12ml TMB color developing agent, 10ml TMB stop solution, 10ml Storage and Stability: Store powder at 4C liquid at -20C.
