Recombinant Human FGFR4

Fibroblast growth factor receptor 4 (FGFR4) is a member of a family of transmembrane receptors with ligand-induced tyrosine kinase activity¹ that is expressed at significant levels in almost all human prostate cancers, and expression of its ligands is ubiquitous.² FGFR4 plays essential roles in systemic lipid and glucose homeostasis.³ FGFR4 may be an important regulator of osteogenesis with involvement in preosteoblast proliferation and differentiation as well as osteoblast functioning during intramembranous ossification.⁴ FGFR-4 signaling and receptor turnover are important potential therapeutic targets in prostate cancer.²

Lyophilized

The predicted molecular weight of Recombinant Human FGF R4 is Mr 65 kDa. However, the actual molecular weight as observed by migration on SDS-PAGE is Mr 100-110 kDa.

65

This recombinant protein was 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 with no calcium, magnesium, or preservatives.

This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
