Invitrogen™ Thapsigargin, 20 x 50 µg

Thapsigargin is a naturally occurring sesquiterpene lactone isolated from the umbelliferous plant Thapsia garganica. This tumor promoter releases Ca2+ from intracellular stores by specifically inhibiting the endoplasmic reticulum Ca2+-ATPase; it does not directly affect plasma membrane Ca2+-ATPases, Ins 1,4,5-P3 production or protein kinase C activity. Thapsigargin is also available in a 1 mg packaging, T7458.
