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.
In contrast to other fluorogenic caspase substrates or fluorescent caspase inhibitor based (FLICA) assays that which inhibit caspase activity, 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.

THE GOLD STANDARD FOR MONITORING APOPTOSIS
NucView® 488 is Validated in More Than 100 Cell Types and 200 Publications
Highlighted Citation: NucView® 488 was used in a T cell-mediated tumor cell killing assay by Lim et al. in a study investigating the role of inflammation on PD-L1 stabilization. Results show T-cell mediated killing of PD-L1 expressing BT549 ductal carcinoma cells was no longer suppressed when treated with neutralizing TNF-α antibody. In addition, PD-L1 depleted cells did not respond to either cytokine enriched macrophage-conditioned medium (MP) or TNF-α antibody, suggesting that PD-L1 expression is required for TNF- α-mediated suppression of T cell activity.
