Recombinant human transforming growth factor-beta 1 (TGF-β1) protein is an essential growth factor in many iPSC and ESC maintenance media, including the commonly used chemically-defined E8-based stem cell culture medias1, StemPro2 and mTeSR1 medias3. To date, recombinant human TGF-β1 has only been produced from mammalian cell protein expression systems (HEK or CHO), where endogenous protein contaminants, cost and animal-free status is a challenge. Our protein experts have optimized TGF-β1 allowing us to produce the first highly bioactive protein in an E. coli fully animal-free expression system.
As part of our ongoing mission to redefine industry standards for growth factor and cytokine biochemical quality, we’re delighted to introduce the first optimized, truly animal-free recombinant human TGF-β1 for our stem cell maintenance range.
- Truly animal-free alternative for chemically-defined stem cell culture media
- High potency in iPSC culture with high pluripotency (Nanog) marker expression
- High purity, extensive biochemical data and exceptional batch-to-batch consistency
