Validation Data Gallery

• 

  Purity of Recombinant Human FGFR3 (IIIb) was determined by SDS-PAGE. The protein was resolved in an SDS-PAGE in reducing (R) and non-reducing (NR) conditions and stained using Coomassie blue.

• 

  Immobilized Human FGF basic (His tag) at 1 μg/mL (100 μL/well) can bind Human FGFR3 (IIIb) (hFc tag, Myc tag, His tag) with a linear range of 95-380 ng/mL.

• 

  The purity of Human FGFR3 (IIIb) was greater than 90% as determined by SEC-HPLC.

Background

FGFR3 (Fibroblast growth factor receptor 3) is a tyrosine-protein kinase that that acts as cell-surface receptor for fibroblast growth factors. FGFR3 binds acidic and basic fibroblast GH and plays important roles in development, osteogenesis, and bone maintenance. FGFR3 is highly expressed in chondrocytes and osteoblasts, and germline mutations are associated with bone growth disorders such as achondroplasia, chondrodysplasia, and thanatophoric dysplasia. Due to frequent mutations in certain cancers, FGFR3 gene has also been associated with tumor progression.
