Specifications

Selective inhibitor of the mitogen-activated protein kinase kinases, MEK-1 and MEK-2, with 100-fold higher potency than PD 98059, but is, at most, a weak inhibitor of PKC, Raf, ERK, JNK, MEKK, MKK-3, MKK-4/SEK, MKK-6, Abl, Cdk2 and Cdk4. U0126 is an inhibitor of AP-1 transactivation in cell-based reporter assays.
Catalog #M2865-50A
In aqueous and certain organic solvents M2865-50A exists as an equilibrium mixture of 2 isomers which cannot be permanently separated. The 2 individual isomers have equivalent biological activity because they give rise to the same equilibrium mixture of isomes in aqueous solutions.
SolubilitySoluble in DMSO at 200mg/ml. Very poorly soluble in ethanol and water. Maximum solubility in plain water is estimated to be about 10-50uM.
Melting Point156-159ºC
Storage and StabilityMay be stored at RT for short-term only. Long-term storage is recommended at -20°C. For maximum recovery of product, centrifuge the original vial prior to removing the cap.
