Product nameBTS, Ca2+-stimulated myosin S1 ATPase
DescriptionSelective inhibitor of Ca2+-stimulated myosin S1 ATPase
Selective inhibitor of Ca2+-stimulated myosin S1 ATPase (IC50 = ~5 µM). Reversibly blocks the gliding motility and weakens myosin’s interaction with F-actin. Much less effective in suppressing contraction in rat myocardial or rabbit slow twitch muscle and has no effect on platelet myosin II.
Storage instructionsStore at -20°C. Store under desiccating conditions. The product can be stored for up to 12 months.
Solubility overviewSoluble in DMSO
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.
