“Our lab has been using FGF2 and activin A from Qkine in stem cell cultures for many months now. Our epiblast stem cells and trophoblast stem cells never looked better. Qkine has provided us with exceptional customer service and most importantly top-quality, affordable growth factors. We will be definitely using their products in the future.”
