High quality, high purity and low endotoxin recombinant Recombinant Human FGF-18 Protein (RPCB1853), tested reactivity in HEK293 cells and has been validated in SDS-PAGE.100% guaranteed.
Endotoxin:
< 0.1 EU/μg of the protein by LAL method.
Purity:
≥ 95 % as determined by SDS-PAGE.
Formulation:
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
Bio-Activity:
Measured by its binding ability in a functional ELISA. Immobilized Human FGF18(RPCB1853) at 10 μg/mL (100 μL/well) can bind Human FGFR4 (RPCB0225) with a linear range of 27.4-393.3 ng/mL.
Reconstitution:
Centrifμge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
Storage:
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
Fibroblast growth factor 18 (FGF18) is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth, and invasion. It has been shown in vitro that FGF18 is able to induce neurite outgrowth in PC12 cells. Studies of the similar proteins in mouse and chick suggested that this protein is a pleiotropic growth factor that stimulates proliferation in a number of tissues, most notably the liver and small intestine. Experiment datas identified FGF18 as a selective ligand for FGFR3 in limb bud mesenchymal cells, which suppressed proliferation and promoted their differentiation and production of cartilage matrix. FGF18 appears to regulate cell proliferation and differentiation positively in osteogenesis and negatively in chondrogenesis.
Recombinant Human FGF-18 Protein was determined by SDS-PAGE under reducing conditions with Coomassie Blue.
Immobilized Human FGF18(RPCB1853) at 10 μg/mL (100 μL/well) can bind Human FGFR4 (RPCB0225) with a linear range of 27.4-393.3 ng/mL.
