Thapsigargin
Tocris Bioscience, part of Bio-Techne | Catalog # 1138
Potent inhibitor of SERCA ATPase
Product Description
Thapsigargin is a potent inhibitor of sarco/endoplasmic reticulum Ca2+-ATPases (SERCA) that causes endoplasmic reticulum (ER) stress. Thapsigargin can be used to induce autophagy in mammalian cells. In vitro, thapsigargin blocks infection of immortilized and primary human cells with respiratory syncytial virus (RSV), SARS-CoV-2 and influenza A. Thapsigargin protects mice against lethal influenza A viral infection and reduces virus titres in the lungs of treated mice.Product Specifications
