PTPRJ ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Density Enhanced Phosphatase 1 (DEP1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Density Enhanced Phosphatase 1 (DEP1) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

CD148; CD148 antigen; density-enhanced phosphatase 1; DEP1; DEP-1; HPTP eta; HPTPeta; human density enhanced phosphatase-1; protein tyrosine phosphatase, receptor type, J polypeptide; protein-tyrosine phosphatase eta; Protein-tyrosine phosphatase receptor type J; receptor-type tyrosine-protein phosphatase eta; R-PTP-ETA; R-PTP-J; SCC1; susceptibility to colon cancer 1, mouse, homolog of.

Tyrosine phosphatase which dephosphorylates or contributes to the dephosphorylation of CTNND1, FLT3, PDGFRB, MET, RET (variant MEN2A), KDR, LYN, SRC, MAPK1, MAPK3, EGFR, TJP1, OCLN, PIK3R1 and PIK3R2. Plays a role in cell adhesion, migration, proliferation and differentiation. Involved in vascular development. Regulator of macrophage adhesion and spreading. Positively affects cell-matrix adhesion. Positive regulator of platelet activation and thrombosis. Negative regulator of cell proliferation. Negative regulator of PDGF-stimulated cell migration; through dephosphorylation of PDGFR. Positive regulator of endothelial cell survival, as well as of VEGF-induced SRC and AKT activation; through KDR dephosphorylation. Negative regulator of EGFR signaling pathway; through EGFR dephosphorylation. Enhances the barrier function of epithelial junctions during reassembly. Negatively regulates T-cell receptor (TCR) signaling. Upon T-cell TCR activation, it is up-regulated and excluded from the immunological synapses, while upon T-cell-antigen presenting cells (APC) disengagement, it is no longer excluded and can dephosphorylate PLCG1 and LAT to down-regulate prolongation of signaling.

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 Density Enhanced Phosphatase 1 (DEP1) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Density Enhanced Phosphatase 1 (DEP1) . 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 Density Enhanced Phosphatase 1 (DEP1), 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 Density Enhanced Phosphatase 1 (DEP1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
