Recommended Products
There are no recommended products for Recombinant Porcine TGF-β3 Protein
Overview
Porcine TGF beta 3 protein is a member of the transforming growth factor family, a family involved in regulating cell survival, proliferation and differentiation. Qkine is dedicated to supporting the cellular agriculture industry by manufacturing high-purity and bioactive growth factors that are species-specific to cultivated cultures. Porcine TGF-β3 is used in cultivated meat pluripotent stem cell maintenance medias, such as Beefy9 media.
Porcine TGF beta 3 is a protein dimer that is animal-origin free (AOF) and carrier-protein free (CF).

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).
