BTS is a selective inhibitor of the ATPase activity of skeletal muscle myosin II subfragment 1 (S1) (IC50 ~ 5 mM). Reversibly blocks gliding motility and suppresses force and twitch production in fast skeletal muscle.
BTS is also offered as part of the Tocriscreen 2.0 Max. Find out more about compound libraries available from Tocris.
