Irreversible, cell permeable broad-spectrum caspase inhibitor.

Product Specification

Alternative Name:Caspase family inhibitor (fluoromethylketone)
 
Sequence:Boc-Asp(OMe)-fluoromethylketone
 
Formula:C11H18FNO5
 
MW:263.3
 
CAS:187389-53-3
 
Purity:≥95% (TLC)
 
Appearance:White to off-white powder.
 
Solubility:Soluble in DMSO or dimethyl formamide.
 
Shipping:Ambient
 
Long Term Storage:-20°C
 
Use/Stability:Stock solutions should be divided into aliquots and stored at -20°C. For long term storage keep aliquots at -70°C.
 
Handling:Keep cool and dry. After reconstitution, prepare aliquots and store at -80°C.
 
Technical Info/Product Notes:The carboxyl groups are OMe ester form to enhance cell permeability. If purified enzyme is used, esterase should be added for the hydrolysis of the ester groups.
 
Protocol:Prepare a 20 mM stock solution of the caspase inhibitor in DMSO. Add 1 µl of above stock solutions to 1 ml of culture medium containing cells to give 20 mM final concentration. DMSO concentration above of 0.2 % may cause cellular toxicity thus masking the effect of the ICE-protease inhibitor Boc-D(OMe)-FMK. For in vivo experiments extending for 12 to 48 hours, fresh inhibitor may have to be added (injected) due to inactivation by reaction with cysteine protease.
