-
Engineered mature domain of human activin A expressed in E.coli, refolded and purified to homogeneity. Optimised for extremely consistent high yield and the same bioactivity as wild-type protein. Particularly suitable for larger scale and bulk stem cell culture. Protein is lyophilised (carrier protein-free).
-
Recombinant mature domain of human activin A protein (residues 311-426, Uniprot: P08476) expressed in E.coli (animal-derived component free). Protein supplied lyophilised with no carrier protein present. Activin A is used in stem cell maintenance and differentiation.
-
Mature domain of human BMP-2 (residues 311-426, Uniprot: P08476) expressed in E.coli, refolded and purified to homogeneity. Protein is lyophilised (carrier protein-free)
-
Epidermal growth factor (EGF) recombinant protein for induced-pluripotent stem cell (iPSC), embryonic stem cell (ESC) and organoid culture. For successful expansion and differentiation of epithelial, neural, mesoderm and hematopoietic lineages. Use along with other stem cell niche factors, R-spondin 1, Noggin or Gremlin, Wnt3a and FGF10, in defined and animal-derived component free media for establishing and maintaining intestine, stomach, liver, pancreas, brain and cancer organoids.
