• Qk001: Activin A (human)

    Recombinant mature domain of human Activin A protein (residues 311-426, Uniprot: P08476) expressed in E.coli (animal-derived component free).  Protein supplied lyophilized with no carrier protein present. Activin A is used in stem cell maintenance and differentiation.
  • Qk005: Activin A Plus (human)

    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).
