1. What is Thapsigargin? Frequently Asked Questions

    What is Thapsigargin? Frequently Asked Questions
    Thapsigargin is derived from the plant Thapsia garganica that produces tumor promoters. This effect is a result of emptying the intracellular calcium stores, which leads to a chain of events that causes apoptosis. Mechanism of Action Chemical structure of Thapsigargin Thapsigargin is an inhibitor of sarco endoplasmic reticulum Ca2 ATPase (SERCA). It pumps calcium ions from the cytoplasm into the lumen...

    RNase A: Frequently Asked Questions
    Introduction to RNase Ribonucleases (RNases) are a large group of hydrolytic enzymes that degrade ribonucleic acid (RNA) molecules. These are nucleases that catalyze the breakdown of RNA into smaller components. They are a superfamily of enzymes which catalyze the degradation of RNA, operating at the levels of transcription and translation. 3D conformation of ribonuclease A enzyme These enzymes are present...
  3. 19 X-GAL Facts and Uses You Should Know!

    X-gal is an analog of lactose, and therefore may be hydrolyzed by the β-galactosidase enzyme which cleaves the β-glycosidic bond in D-lactose.
  4. GSK-3, WNT Signaling: Cancer Treatment

    MECHANISM The Wnt pathway involves a large number of proteins that can regulate the production of Wnt signaling molecules, their interactions with receptors on target cells and the physiological responses of target cells that result from the exposure of cells to the extracellular Wnt ligands. Although the presence and strength of any given effect depends on the Wnt ligand, cell...
  5. Why should it be AG Scientific's HRV3C Protease?

    Why should it be AG Scientific's HRV3C Protease? Human rhinovirus 3C protease (HRV 3C Protease) is a cysteine protease that recognizes the cleavage site of Leu-Glu-Val-Leu-Phe-Gln-Gly-Pro, commonly referred to as the PreScission Site. It cleaves between Gln and Gly. The recombinant form of the HRV3C protease is a restriction grade protease that has robust activity at 4°C and high specific...
