Medchemexpress LLC Fibroblast growth factor receptor 1 beta protein, human, hFc-tagged | 91.9% | 100UG

Supplier:  Medchemexpress LLC HYP700436100UG

Recombinant human FGFR-1 beta extracellular domain fused to human Fc (hFc), expressed in HEK293 cells and supplied lyophilized for research use. The protein is formulated in 20 mM PB, 150 mM NaCl, pH 7.4, exhibits low endotoxin (<1 EU/μg), and shows bioactivity with an ED50 of 1.096 ng/mL in the presence of 1 ng/mL FGF-1. Reconstitute to ≥100 μg/mL and store aliquots at -20°C or -80°C.

• Fc-tagged extracellular domain suitable for receptor binding and bioassays.
• Expressed in HEK293 for human-like glycosylation and folding.
• Lyophilized formulation for enhanced stability and transport.
• Low endotoxin level supports cell-based assay use.
• High specific activity (ED50 ~1.096 ng/mL) for reproducible results.
• Clear reconstitution and storage guidance to preserve activity.
