Storage: Store at or below -20 ºC. Solubility: Soluble in DMSO at 25 mg/mL; soluble in ethanol at 1 mg/mL with warming; very poorly soluble in water; maximum solubility in plain water is estimated to be about 50-100 µM; buffers, serum, or other additives may increase or decrease the aqueous solubility. Disposal: A.
- More than 1,000 labs worldwide have purchased PD 98059 from LC Labs (either directly from us or from our many distributors, many of whom resell under their own labels).
- Potent, selective and cell-permeable inhibitor of MAP kinase kinase (also known as MAPK/ERK kinase or MEK kinase). Inhibits phosphorylation of MAP kinase by MAP kinase kinase. PD 98059 does not inhibit MAP kinase itself. IC50 values for PD 98059-induced effects are in the 1-20 µM range for many assays; it is somewhat weaker in inhibiting cell growth in monolayers or agar for some cell lines. Dudley, D.T., et al.
