PTPRS ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Protein Tyrosine Phosphatase Receptor Type S (PTPRS) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Protein Tyrosine Phosphatase Receptor Type S (PTPRS) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

Protein tyrosine phosphatase PTPsigma; PTPSIGMA; receptor-type tyrosine-protein phosphatase S; receptor-type tyrosine-protein phosphatase sigma; R-PTP-S; R-PTP-sigma.

Cell surface receptor that binds to glycosaminoglycans, including chondroitin sulfate proteoglycans and heparan sulfate proteoglycan (PubMed:21454754) . Binding to chondroitin sulfate and heparan sulfate proteoglycans has opposite effects on PTPRS oligomerization and regulation of neurite outgrowth. Contributes to the inhibition of neurite and axonal outgrowth by chondroitin sulfate proteoglycans, also after nerve transection. Plays a role in stimulating neurite outgrowth in response to the heparan sulfate proteoglycan GPC2. Required for normal brain development, especially for normal development of the pituitary gland and the olfactory bulb. Functions as tyrosine phosphatase (PubMed:8524829) . Mediates dephosphorylation of NTRK1, NTRK2 and NTRK3 (By similarity) . Plays a role in down-regulation of signaling cascades that lead to the activation of Akt and MAP kinases (By similarity) . Down-regulates TLR9-mediated activation of NF-kappa-B, as well as production of TNF, interferon alpha and interferon beta (PubMed:26231120) .

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Protein Tyrosine Phosphatase Receptor Type S (PTPRS) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Protein Tyrosine Phosphatase Receptor Type S (PTPRS) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Protein Tyrosine Phosphatase Receptor Type S (PTPRS), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Protein Tyrosine Phosphatase Receptor Type S (PTPRS) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
