Tag
His Tag (C-term)
Description
Fibroblast Growth Factors-4 (FGF-4) is a 22 kDa member of the fibroblast Growth Factors with 206 amino acid residues. FGF-4 can regulate embryonic development, cell proliferation, and cell differentiation. FGF-4 is an important role development during embryogenesis.
Storage & Handling
Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.

Form
Lyophilized
Formulation
The protein was lyophilized from a 0.2 μm filtered solution containing 0.1% sarkosyl in 1X PBS, pH 8.0. If you have any concerns or special requirements, please confirm with us.
Purity
>95% as determined by SDS-PAGE.
Predicted MW
22.0 kDa
Molecular weight
The protein has a calculated MW of 20.70 kDa. The protein migrates as 22 kDa under reducing condition (SDS-PAGE analysis).
Activity
Measure by its ability to induce 3T3 cells proliferation. The ED₅₀ for this effect is <2.5 ng/mL. The specific activity of recombinant human FGF-4 is > 4 x 10⁵ IU/mg.
Endotoxin
<0.1 EU per 1 μg of the protein by the LAL method.

Reconstitution
Centrifuge at 3000 rpm for 5 mins before opening. It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 100 μg/mL and incubate the stock solution at room temperature for at least 20 mins to ensure sufficient re-dissolved. Do Not Vortex! Vigorous shaking may impair the biological activity of the protein.
