- Theoretical Molecular Weight
- The protein has a predicted MW of 19.29 kDa. The protein migrates to 20-24 kDa based on Bis-Tris PAGE result.
- Purity
- > 95% as determined by Bis-Tris PAGE
- Endotoxin
- Less than 0.1 EU per μg by the LAL method.
- Buffer / Formulation
- Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
- State
- Lyophilized
- Storage Conditions
- -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
- Reconstitution Advice
- Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.
Data Display
Human FGF4 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
Measured in a cell proliferation assay using Balb/c 3T3 mouse fibroblasts. The ED50 for this effect is typically 0.1 - 1 ng/mL (QC Test).
Background
Fibroblast growth factor-4 (FGF-4), a highly mitogenic protein encoded by the k-fgf/hst oncogene, stimulates the growth of a variety of cells of mesenchymal and neuroectodermal origin. It is a member of the FGF family and plays several important roles in bone development during embryogenesis.
