PD98059 is a potent and selective MEK inhibitor with an IC₅₀ of 5 µM. PD98059 binds to the inactive form of MEK, thereby preventing the activation of MEK1 (IC₅₀ of 2-7 µM) and MEK2 (IC₅₀ of 50 µM) by upstream kinases. PD98059 is a ERK1/2 signaling inhibitor. PD98059 is a ligand for the aryl hydrocarbon receptor (AHR), and suppresses TCDD binding (IC₅₀ of 4 μM) and AHR transformation (IC₅₀ of 1 μM). PD98059 also inhibits Mycobacterium bovis Bacillus CalmetteGuerin (BCG)-induced autophagy.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
