Mechanism of Action

Information	Z-VAD-FMK is a cell-permeant, irreversible pan-caspase inhibitor. It binds to the catalytic site of caspase proteases, blocking caspase-dependent apoptosis, pyroptosis, and related proteolytic signaling pathways. It is widely used to distinguish cell death mechanisms.

Frequently Asked Questions

Question 1:
Can you suggest an in vivo formulation of it for animal studies?

Answer:
For in vivo study of this compound, the IP formulation is 2% DMSO+35 % PEG 300+2% Tween 80+ddH2O up to 6 mg/ml. The gavage formula is 1%CMC-Na up to 30 mg/ml (suspensions).

Question 2:
What is the difference between S7023 & S8102?

Answer:
Unlike S7023, it does not require pretreatment with esterase for in vitro studies. This information was cited from the article: https://www.ncbi.nlm.nih.gov/pubmed/16973565.

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration _(start) x Volume _(start) = Concentration _(final) x Volume _(final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

*When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).
