Human FGF4 Protein (FGF-HE004) Summary

Product Description

 Recombinant Human FGF4 Protein is expressed from E.coli without tag.It contains Ala31-Leu206.

Product 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.

Shipping, Reconstitution, & Storage

Form
 Lyophilized
Shipping
 Shipped at ambient temperature.
Formulation
 Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution
 Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.
Stability And Storage
 -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.
