The PathScan® Phospho-FGF Receptor 3 (panTyr) Chemiluminescent Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of tyrosine-phosphorylated FGFR3 protein with a chemiluminescent readout. Chemiluminescent ELISAs often have a wider dynamic range and higher sensitivity than conventional chromogenic detection. This chemiluminescent ELISA, which is offered in low volume microplates, shows increased signal and sensitivity while using a smaller sample size. An FGFR3 rabbit mAb has been coated on the microwells. After incubation with cell lysates, both phospho- and nonphospho-FGFR3 proteins are captured by the coated antibody. Following extensive washing, a phospho tyrosine mouse mAb is added to detect the captured tyrosine-phosphorylated FGFR3 protein. Anti-mouse IgG, HRP-linked antibody is then used to recognize the bound detection antibody. Chemiluminescent reagent is added for signal development. The magnitude of light emission, measured in relative light units (RLU), is proportional to the quantity of tyrosine-phosphorylated FGFR3 protein.
Antibodies in kit are custom formulations specific to kit.
PathScan® Phospho-FGF Receptor 3 (panTyr) Chemiluminescent Sandwich ELISA Kit #64740 detects endogenous levels of tyrosine-phosphorylated FGFR3 in human cells. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.
Fibroblast growth factors (FGFs) produce mitogenic and angiogenic effects in target cells by signaling through cell surface receptor tyrosine kinases. There are four members of the FGF receptor family: FGFR1 (flg), FGFR2 (bek, KGFR), FGFR3, and FGFR4. Each receptor contains an extracellular ligand binding domain, a transmembrane domain, and a cytoplasmic kinase domain (1). Following ligand binding and dimerization, the receptors are phosphorylated at specific tyrosine residues (2). Seven tyrosine residues in the cytoplasmic tail of FGFR1 can be phosphorylated: Tyr463, 583, 585, 653, 654, 730, and 766. Tyr653 and Tyr654 are important for catalytic activity of activated FGFR and are essential for signaling (3). The other phosphorylated tyrosine residues may provide docking sites for downstream signaling components such as Crk and PLCγ (4,5).
Activating mutations within fibroblast growth factor receptor 3 (FGFR3) are responsible for human skeletal dysplasias including achondroplasia and the neonatal lethal syndromes thanatophoric dysplasia types I and II (6,7). Several of these same FGFR3 mutations as well as overexpression of FGFR3 proteins have also been identified somatically in human cancers, including multiple myeloma, bladder carcinoma and cervical cancer (8). Thus, FGFR3 may represent a potential target for therapy.
