KC04011 | Caspase-9 Colorimetric Assay Kit

268.00535.00 TAX excl.

Caspase-9 Colorimetric Assay Kit provides a simple procedure for assaying the activity of caspases that recognize the sequence LEHD. Hence, the user can detect the chromophore p-nitroanilide (pNA), after cleavage from the labeled substrate LEHD-pNA. The pNA can be quantified using a spectrophotometer or a microplate reader at 405 nm.  Comparison pNA absorbance from an apoptotic sample vs absorbance of control allows determination of the fold increase in caspase-9 activity

There are two classes of caspases that involve apoptosis; initiators and effectors. Proapoptotic signals autocatalytically activate initiator caspases, such as Caspase 8 and Caspase 9. As a consequence, activated initiator caspases then process effector caspases, such as Caspase 3 and Caspase 7, which in turn cause cell collapse. As a resume, initiator caspases (caspase 2, 8, 9, and 10) initiate the apoptosis signal and the executioner caspases (caspase 3, 6, and 7) carry out the mass proteolysis that leads to apoptosis.
