Biological descriptionStandard phospholipase C inhibitor (PLC) (IC50 = ~6 µM at PLC-β3). Shows a variety of biological activities including antiplatelet activation, Ca2+ signaling modulation and inhibition of 5-lipoxygenase activity. Active in vivo.
Storage instructionsStore at Room Temperature. The product can be stored for up to 12 months.
Solubility overviewSoluble in DMSO to 10 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
