Z-DEVD-R 110

Z-DEVD-R 110 is a rhodamine-based, DEVD-recognizing fluorescence reagent designed for caspase-3/7 activity readouts in chemical biology workflows. The DEVD recognition element enables activity-dependent fluorescence generation or recovery when incorporated into assay formats used to monitor apoptosis-related protease activity and downstream signaling in cell extracts or cultured cells. Its bright rhodamine emission supports fluorescence microscopy and plate-based quantification, making it a common tool for researchers building protease activity assays and apoptosis phenotyping experiments.

1. Caspase Activity Assays

Z-DEVD-R 110 is used to monitor caspase-3/7 activity in fluorescence-based protease assays, where activity-dependent signal change provides a direct readout of DEVD proteolysis. Researchers in apoptosis research, drug discovery support, and pathway-focused chemical biology studies employ this reagent in microplate formats to compare protease activity across experimental conditions, including time-course studies and stimulus-response experiments. The rhodamine fluorophore architecture supports sensitive visualization in standard fluorescence instrumentation commonly used for enzymatic activity screening.

2. Fluorescence Microscopy Readouts

Z-DEVD-R 110 is applied for cellular imaging workflows aimed at visualizing protease activity in fixed or permeabilized cell preparations, supporting spatial mapping of caspase activation within heterogeneous samples. Cell biologists and imaging specialists use rhodamine fluorescence to correlate protease activity with cellular morphology and experimental perturbations, often alongside membrane or nuclear stains to provide contextual information. This makes the reagent useful for microscopy-based phenotyping where localization and distribution of protease activity are important.

3. Flow Cytometry Protease Profiling

Z-DEVD-R 110 is leveraged in flow cytometry studies to quantify caspase-3/7 activity at the single-cell level, enabling population-level comparison of protease activation states. Researchers use the fluorescence signal to gate subpopulations and track shifts in protease activity distributions across treatments, time points, or genetic backgrounds. The rhodamine emission is compatible with common flow cytometer fluorescence channels used for red/orange detection, supporting routine assay development for protease profiling experiments.

4. Apoptosis Pathway Screening

Z-DEVD-R 110 is frequently used as a functional readout reagent in apoptosis pathway screening workflows that evaluate how experimental conditions influence caspase activation. In chemical biology and medicinal chemistry research settings, the reagent supports assay development for protease-driven phenotyping, including validation of pathway engagement and comparison of candidate compound effects on caspase activity in relevant experimental models. Its activity-linked fluorescence response helps translate protease activation into a measurable signal for downstream data analysis and experiment-to-experiment consistency.
