Stemfactor Activin A is a crystallography-grade preparation providing the highest purity available. Activin A is bi-modal in action having been shown to maintain pluripotency of stem cells and promote differentiation1,2,3,4. Mature recombinant human Activin A is a ~25 kDa disulfide-linked homodimer of two 116 amino acid residue βA subunits.
Stemgent conveniently provides all the components comprising the 5i/L/A media supplement necessary to support naïve pluripotent stem cell applications.
