Monitor apoptosis in real-time with NucView®!

How it works

NucView® Caspase-3 Substrates are based on novel fluorogenic DNA dyes that have been coupled to the caspase-3/7 recognition sequence (DEVD). When introduced to cells, the 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. Consequently, NucView® Caspase-3 Substrates are bifunctional, allowing detection of caspase-3/7 activity and visualization of morphological changes in the nucleus during apoptosis.

Principle of NucView® substrate technology. The substrate is non-fluorescent and does not bind DNA. After enzyme cleavage, the high-affinity DNA dye is released and fluoresces upon binding to DNA.

In contrast to other fluorogenic caspase substrates or similar assays, NucView® Caspase-3 Substrates can be used to detect caspase-3/7 activity in live cells without inhibiting apoptosis progression. Staining is also compatible with subsequent fixation and permeabilization for downstream immunostaining.

Advantages of NucView® Caspase-3 Substrates
