Biotin-VAD-FMK is a cell-permeable, irreversible, biotin-labeled caspase inhibitor used to detect and label active caspases in cell lysates. The FMK electrophile covalently modifies active caspase catalytic residues, and the biotin tag enables downstream capture or detection with streptavidin-based reagents. Common uses include activity profiling and affinity capture in apoptosis research.
- Detects and labels active caspases in cell lysates.
- Covalent binding via FMK electrophile for durable labeling.
- Biotin tag enables streptavidin-based capture or detection.
- Cell-permeable for use in intact cells and lysates.
- Suitable for pull-downs, western blotting, and activity profiling.
- Stable powder with recommended frozen storage for long-term retention.
