Activins

Activins are members of the transforming growth factor-beta (TGF-β) family of proteins which includes ligands, receptors and signaling molecules with essential roles in growth, differentiation and proliferation in a wide range of cell types. Activins are secreted proteins which function as dimers of two inhibinβ chains linked by a disulfide bond. Members of the activin class include activin A, activin B, activin C, and activin E, and extend to include GDF-8 (myostatin) and GDF-11 (BMP-11).

Qkine robust animal-free manufacturing platform, along with rigorous quality control procedures, ensure that all our activin proteins are:

  • animal origin-free (AOF) and carrier protein-free
  • highly pure (>98%, by SDS-PAGE quantitative densitometry)
  • highly bioactive (equally or more bioactive than other dominant suppliers) and come with our Bioactivity Guarantee
  • highly reproducible with excellent lot-to-lot consistency

Qkine is committed to manufacturing bioactive proteins of the highest quality to enhance scientific outcomes and improve reproducibility. Our stringent quality control procedures in place ensure your results are reliable and reproducible every time.  We couple this with unrivaled lot-to-lot consistency, ensuring every single batch meets the same quality standards as all previous ones, thereby reducing the need for batch testing. All our products rigorously adhere to the Nine-point Qkine Quality Commitment.

Please contact us if you have any questions. Our dedicated team of stem cell specialists is available to answer any queries.
