FGFR4 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level FGFR4 were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level FGFR4 were tested on 3 different plates, 8 replicates in each plate. Intra-Assay: CV Inter-Assay: CV Inter-Assay: CV Inter-Assay: CV

CD334; fibroblast growth factor receptor 4; hydroxyaryl-protein kinase; JTK2; protein-tyrosine kinase; TKF; tyrosine kinase related to fibroblast growth factor receptor; tyrosylprotein kinase.

Tyrosine-protein kinase that acts as cell-surface receptor for fibroblast growth factors and plays a role in the regulation of cell proliferation, differentiation and migration, and in regulation of lipid metabolism, bile acid biosynthesis, glucose uptake, vitamin D metabolism and phosphate homeostasis. Required for normal down-regulation of the expression of CYP7A1, the rate-limiting enzyme in bile acid synthesis, in response to FGF19. Phosphorylates PLCG1 and FRS2. Ligand binding leads to the activation of several signaling cascades. Activation of PLCG1 leads to the production of the cellular signaling molecules diacylglycerol and inositol 1,4,5-trisphosphate. Phosphorylation of FRS2 triggers recruitment of GRB2, GAB1, PIK3R1 and SOS1, and mediates activation of RAS, MAPK1/ERK2, MAPK3/ERK1 and the MAP kinase signaling pathway, as well as of the AKT1 signaling pathway. Promotes SRC-dependent phosphorylation of the matrix protease MMP14 and its lysosomal degradation. FGFR4 signaling is down-regulated by receptor internalization and degradation; MMP14 promotes internalization and degradation of FGFR4. Mutations that lead to constitutive kinase activation or impair normal FGFR4 inactivation lead to aberrant signaling.

Aviva Systems Biology FGFR4 ELISA Kit (Human) (OKDD00266) is based on standard sandwich enzyme-linked immuno-sorbent assay methodology. An antibody for FGFR4 has been pre-coated onto a 96-wellplate (12 x 8 Well Strips) . Standards or test samples are added to the wells, incubated and removed. A biotinylated detector antibody specific for FGFR4 is added, incubated and removed. Avidin-Peroxidase Conjugate is then added, incubated and unbound conjugate is washed away. An enzymatic reaction is produced through the addition of TMB substrate which is catalyzed by HRP generating a blue color product that changes yellow after adding acidic stop solution. The density of yellow coloration read by absorbance at 450 nm and is quantitatively proportional to the amount of sample FGFR4 captured in well.
