Purity Detail:In solution, U 0126 forms a mixture of isomers, but this does not affect biological activity.
Appearance:White solid
Solubility:Soluble in DMSO (>10mg/ml) or 100% ethanol (2mg/ml).
Shipping:Ambient Temperature
Long Term Storage:Ambient
Use/Stability:Store, as supplied, at room temperature for up to 1 year.  Store solutions at -20°C for up to 3 months.
Scientific Background:Binding of extracellular growth factors to cell surface receptors often results in actiavtion of the mitogen-ativated protein kinase (MAPK).  MAPK is regulated by MAPK kinase , also called MEK. Deprivation of growth factors during cell culture or intracellular MEK inhibition leads to inhibition of proliferation and apoptotic cell death. N Blank et al. (2002) have shown that U0126, a common used MEK inhibitor and compound that itself has no intrinsic fluorescence in vitro but develops an intensive fluorsecence during cell culture which can be observed in all fluorescence channels with a predominance in the FL1 channel (525nm). Therefore either the use of PD98,059 or PD184352 as an alternative for U126 or nonfluorometric methods for detection of apoptosis should be considered.
