PS48 --- PDK1 Activator

Catalog No. size PriceQuantity
M60026-5S 5 mg solid $79


PS48 is a novel PDK1 (phosphoinositide-dependent protein kinase 1) activator (Kd = 10.3 μM), which binds to the HM/PIF binding pocket rather than the ATP-binding site. PS48 has been used to enhance iPSC reprogramming from human epidermal keratinocytes and endothelial cells.
