How it works ?
 
When introduced to cells, the NucView substrate is initially non-fluorescent and is able to penetrate the plasma membrane and enter the cytoplasm. During apoptosis, caspase-3/7 cleaves the substrate and releases the high-affinity DNA dye which leads to nuclear fluorescent staining.
 
 
About NucView®
 
NucView® substrates consist of a fluorogenic DNA dye coupled to the caspase-3/7 DEVD recognition sequence. The substrate, which is initially non-fluorescent, penetrates the plasma membrane and enters the cytoplasm. In apoptotic cells, caspase-3/7 cleaves the substrate, releasing the high-affinity DNA dye, which migrates to the cell nucleus and stains DNA with fluorescence. Thus, NucView caspase-3 substrates are bifunctional, allowing detection of caspase-3/7 activity and visualization of morphological changes in the nucleus during apoptosis.
 
In contrast to other fluorogenic caspase substrates or fluorescent caspase inhibitor based (FLICA) assays, NucView® caspase-3 substrates can be used to detect caspase-3/7 activity within individual intact cells without inhibiting apoptosis progression. Staining is compatible with subsequent fixation and permeabilization for immunostaining.
 
NucView® substrates are offered as solutions in DMSO or phosphate-buffered saline (PBS). The substrates in PBS are formulated for use in cells that are sensitive to DMSO toxicity. In non-DMSO sensitive cell types, adding DMSO during the substrate incubation may enhance NucView® staining.
