We exclusively use Peprotech's recombinant proteins (human and murine). They have always performed well in our experiments and we have not had any issues yet.

My lung organoids grow well consistently even after passaging it couple of times and there were no  contamination issues.

My lab has been using this product for many years and it always works perfectly. We once purchased it from a different manufacturer due to a relative lower price. However, we found that we must increase the dose if the Activin A is not from Peprotech. As such, the cost went up as we had to use higher dose to make it work. Hence, we learnt that Activin A’s purity and quality from Peprotech is superior.
