Caspase-2 Assay Kit, Fluorometric with Ac-VDVAD-AFC substrate


General description

Activation of ICE-family proteases/caspases initiates apoptosis in mammalian cells. The Caspase-2 Fluorometric Assay Kit provides a simple and convenient means for assaying the activity of caspases that recognize the sequence VDVAD. The assay is based on detection of cleavage of substrate VDVAD-AFC (AFC: 7-amino-4-trifluoromethyl coumarin). VDVAD-AFC emits blue light (λmax = 400 nm); upon cleavage of the substrate by Caspase-2 or related caspases, free AFC emits a yellow-green fluorescence (λmax = 505 nm), which can be quantified using a fluorometer or fluorescence microtiter plate reader.


Detection Method:        Fluorescence (400 nm excitation filter and 505 nm emission filter)

Species Reactivity:        Mammalian

Applications:                  Detect early/middle stages of apoptosis; differentiate apoptosis from necrosis

Storage temp.:               -20°C


Features & Benefits:

  • Simple one-step procedure that takes ~1-2 hours
  • Fast and convenient
  • Comparison of the fluorescence of AFC from an apoptotic sample with an uninduced control allows determination of the fold increase in Caspase-2 activity


Kit Components :

  • Cell Lysis Buffer
  • 2X Reaction Buffer
  • VDVAD-AFC (1 mM)
  • DTT (1 M)
