Qk035 follistatin-resistant activin A (FRACTA) has equivalent bioactivity to wild-type activin A (Qk001) but does not bind follistatin so is resistant to feedback inhibition. High purity 26 kDa dimer comprising engineered mature domain of activin A protein, animal-free (AF) and carrier-protein free (CF). This specialised activin A has been developed in Marko HyvÖnen’s group in the University of Cambridge.

Background To enhance reproducibility and support scale-up, all Qkine's growth factors and cytokines are:
■ High purity and bioactive
■ Carrier protein free
■ Animal-origin free (AOF) or animal-derived component free (ADCF)

Recombinant follistatin-resistant activin A (FRACTA) has been engineered to prevent binding to the natural inhibitor, follistatin. Activin A activity protein is regulated in vivo by follistatin, a high-affinity inhibitor; follistatin accumulates in stem cell culture, where it inhibits activin A.
