What does caspase inhibitor do?
Caspase inhibitors are attractive hepatoprotective drugs for the treatment of human liver diseases. The broad irreversible caspase inhibitor Z-VAD-fmk showed a protective effect by blocking death receptor–mediated liver injury (Rodriguez et al., 1996).
What is the role of the caspases in apoptosis?
Initiator caspases initiate the apoptosis signal while the executioner caspases carry out the mass proteolysis that leads to apoptosis. Inflammatory caspases do not function in apoptosis but are rather involved in inflammatory cytokine signaling and other types of cell death such as pyroptosis.
Can I fix annexin V stained cells?
Yes, cells can be fixed with formaldehyde after staining. Because Annexin V staining is dependent on calcium, all buffers used for washing and fixation should contain 1.25 mM CaCl2. Fixation may increase the background signal from Ethidium Homodimer III.
Is annexin V an antibody?
Anti-annexin V antibodies (aANVAs) are detected in various diseases like rheumatoid arthritis, systemic lupus erythematosus and anti-phospholipid antibody syndrome. The study of ANV in Acute Myocardial Infarction (AMI) might shed light on hypercoagulability mechanisms in the pathogenesis of acute coronary syndromes.
How does the caspase inhibitor Z-VAD-fmk work?
The caspase inhibitor Z-VAD-FMK alleviates endotoxic shock via inducing macrophages necroptosis and promoting MDSCs-mediated inhibition of macrophages activation. Front Immunol. 10:1824. 3. Chauvier D. et al., 2007.
What is the Z-VAD-fmk inhibitor?
The Z-VAD-FMK inhibitor is designed to be used in both in vivo and in vitro cell based assays to measure the inhibition of apoptosis. Reconstitute 1.0 mg of the Z-VAD-FMK inhibitor in DMSO. A 10 mM stock solution may be made by dissolving 1.0 mg of Z-VAD-FMK in 214 µl DMSO.
What is pan caspase inhibitor?
Pan-Caspase inhibitor. Z-VAD-FMK is a cell-permeable pan-caspase inhibitor that irreversibly binds to the catalytic site of caspase proteases [1]. The peptide is O-methylated in the P1 position on aspartic acid, providing enhanced stability and increased cell permeability. Z-VAD-FMK is used in apoptosis studies and also in inflammasome studies.
When should Z-VAD-fmk be added to inhibit apoptosis?
For inhibition of apoptosis, Z-VAD-FMK should be added at the same time that apoptosis is induced. Z-VAD-FMK is provided at 20mM in DMSO for convenient addition to cell culture or extracts.
