Name : Human FGFR4 beta Protein

Product Source :
Recombinant Human FGFR4 beta Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Pro152-Asp369.[Accession | P22455-1]

Molecular Weight :
The protein has a predicted MW of 26.90 kDa. Due to glycosylation, the protein migrates to 40-60 kDa based on Tris-Bis PAGE result.

Endotoxin Level :
Less than 1EU per μg by the LAL method.

Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC

Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3-6 months after reconstitution.2-8°C for 2-7 days after reconstitution.Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

Product Concentration :
Tris-Bis PAGE Human FGFR4 beta on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Human FGFR4 beta is greater than 95% as determined by SEC-HPLC.

Background :
Fibroblast growth factor receptor 4 (FGF R4), also known as CD334, is a 110 kDa glycosylated transmembrane receptor tyrosine 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.

Synonyms :
FGFR4 beta; CD334; FGF R4; FGFR4; FGFR-4; JTK2; TKF
