Human/mouse/rat recombinant activin A PLUS™ protein is an optimised biologically active truncation of the mature domain of human activin A protein. The EC50 and activity in stem cell culture of activin A PLUS is equivalent to the full mature domain activin A.
High purity 24 kDa dimer comprising truncated mature domain of activin A protein, animal origin-free (AOF) and carrier-protein free (CF). Recombinant activin A PLUS™ is designed to be manufactured at scale for cost-effective, large-scale stem cell culture applications.
- High purity optimized mature domain of human activin A (Uniprot: P08476) – particularly suitable for bulk and scale-up stem cell culture applications
- >98%, by SDS-PAGE quantitative densitometry
- Cross-reactivity: human, mouse (murine), rat
- 24 kDa (dimer)
- Expressed in E. coli
- Animal origin-free (AOF) and carrier protein-free
- Manufactured in our Cambridge, UK laboratories
- Lyophilised from acetonitrile, TFA
- Resuspend in 10mM HCl at >100µg/mL (provided with protein and free of charge), prepare single use aliquots, add carrier protein if desired and store frozen at -20°C or -80°C
