Recombinant Porcine EGF Protein
Recommended Products
There are no recommended products for Recombinant Porcine EGF Protein
Overview
Porcine EGF is an essential growth factor belonging to the epidermal growth factor family that stimulates the proliferation and differentiation of cells. It is used for the differentiation of induced pluripotent stem cells (iPSCs) and embryonic stem cells (ESCs) towards epithelial, neural, mesoderm and hematopoietic lineages. Porcine EGF is becoming rapidly adopted as a species-specific growth factor in the cultivated meat sector. Porcine EGF is also an essential component of many organoid media supporting the culture and differentiation of a wide variety of organoids including intestine and liver organoids.
Porcine EGF has a molecular weight of 6.3 kDa. This protein is animal origin-free, carrier protein-free, His-tag-free and non-glycosylated to ensure a pure recombinant protein with exceptional lot-to-lot consistency.

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).
