The FGFR1 (Phospho-Tyr154) Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect FGFR1 protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated FGFR1 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on FGFR1 phosphorylation.
Qualitative determination of FGFR1 (Phospho-Tyr154) concentration is achieved by an indirect ELISA format. In essence, FGFR1 (Phospho-Tyr154) is captured by FGFR1 (Phospho-Tyr154)-specific primary (1ø) antibodies while the HRP-conjugated secondary (2ø) antibodies bind the Fc region of the 1ø antibody. Through this binding, the HRP enzyme conjugated to the 2ø antibody can catalyze a colorimetric reaction upon substrate addition. Due to the qualitative nature of the Cell-Based ELISA, multiple normalization methods are needed:
| 1. | A monoclonal antibody specific for human GAPDH is included to serve as an internal positive control in normalizing the target absorbance values. |
| 2. | Following the colorimetric measurement of HRP activity via substrate addition, the Crystal Violet whole-cell staining method may be used to determine cell density. After staining, the results can be analysed by normalizing the absorbance values to cell amounts, by which the plating difference can be adjusted. |

| UniProt Protein Function: | FGFR1: a receptor tyrosine kinase of the highly-conserved fibroblast growth factor receptor (FGFR). Binds both acidic and basic fibroblast growth factors and is involved in limb induction. Point mutations cause Pfeffer syndrome (finger and toe malformations and other skeletal errors) and dominant Kallmann syndrome 2. Stem cell leukemia lymphoma syndrome (SCLL) may be caused by a t(8;13)(p12;q12) translocation that fuses a zinc finger gene, ZNF198, to FGFR1. Various myeloproliferative disorders have been linked to translocations that fuse FGFR1 to FOP, FIM, CEP1 or the atypical kinase, Bcr. Inhibitor: SU5402. 20 isoforms of the human protein produced by alternative splicing have been described. |

| NCBI Summary: | The protein encoded by this gene is a member of the fibroblast growth factor receptor (FGFR) family, where amino acid sequence is highly conserved between members and throughout evolution. FGFR family members differ from one another in their ligand affinities and tissue distribution. A full-length representative protein consists of an extracellular region, composed of three immunoglobulin-like domains, a single hydrophobic membrane-spanning segment and a cytoplasmic tyrosine kinase domain. The extracellular portion of the protein interacts with fibroblast growth factors, setting in motion a cascade of downstream signals, ultimately influencing mitogenesis and differentiation. This particular family member binds both acidic and basic fibroblast growth factors and is involved in limb induction. Mutations in this gene have been associated with Pfeiffer syndrome, Jackson-Weiss syndrome, Antley-Bixler syndrome, osteoglophonic dysplasia, and autosomal dominant Kallmann syndrome 2. Chromosomal aberrations involving this gene are associated with stem cell myeloproliferative disorder and stem cell leukemia lymphoma syndrome. Alternatively spliced variants which encode different protein isoforms have been described; however, not all variants have been fully characterized. [provided by RefSeq, Jul 2008] |
