Recombinant Human FGF-1 Protein
Recommended Products
There are no recommended products for Recombinant Human FGF-1 Protein
Overview
Fibroblast Growth Factor 1 (FGF-1) can stimulate growth and differentiation of endothelial and epithelial cells and the development of organoids. FGF-1 can also be used for the maintenance of oligodendrocytes and astroglia as well as bone marrow-derived mesenchymal and hematopoietic stem cells.
Qkine human FGF-1 has a molecular weight of 15.9 kDa. This protein is animal origin-free, carrier-free and tag-free to ensure its purity with exceptional lot-to-lot consistency. Qk071 is suitable for the culture of reproducible mesenchymal, endothelial, hematopoietic, glial, and other relevant cells.

How do I store my proteins?
- Lyophilized store at -20°C or -80°C for up to 2 years
- Reconstituted store at -20 °C or -80 °C
- We recommend that single use aliquots are prepared to avoid freeze-thaw cycles
How do I reconstitute lyophilized protein?
- Check the resuspension solution recommendation on the product datasheet.*
- Centrifuge briefly before reconstituting to ensure all powder is at the bottom of the vial.
- Add sufficient reconstitution solution to give a protein concentration of 0.05–1.0 mg/ml.
- Allow the reconstituted sample to stand at room temperature for >1 minute before gently agitating. Do not vortex and avoid foaming.
- Prepare single-use aliquots whenever possible to avoid freeze-thaw cycles, which can damage the proteins and reduce bioactivity. Store aliquots at -80°C (or -20°C).**
NOTES
*Physiological buffers may cause precipitation of proteins during reconstitution. This is especially important for TGF beta family and other related growth factors, so it is very important that these are reconstituted in Solution A (10 mM HCl, 1:1000 dilution of concentrated HCl).
**All our proteins are supplied carrier protein-free. If compatible with your work and you are storing at lower concentrations (<50 μg/ml), adding carrier protein is highly advised (usually 1% w/v high purity BSA or equivalent – ensure all buffers are sterile-filtered).
