Red Fluorescent SR In vivo Poly (active) Caspase (VAD) Assay

Red Fluorescent SR In vivo Poly (active) Caspase (VAD) Assay

• Description: A non-cytotoxic, cell-permeant fluorescent inhibitor of caspases optimized for use in whole live animals. The probe contains the preferred binding sequence for most caspases (Val-Ala-Asp or VAD), coupled to a SR dye and a FMK reactive entity.
• Assay Principle: 1. Prepare samples and controls, 2. Dilute cellular wash buffer 1:10 with diH2O, 3. Reconstitute FLISP with 50 µL DMSO, 4. Dilute FLISP 1:5 by adding 200 µL PBS, 5. Add 10 µL FLISP to each sample (~500 µL aliquot of cultured cells), 6. Incubate ~ 1 hour., 7. Remove media and wash cells: add wash buffer and spin cells (twice); or add fresh media and incubate 1 hour, 8. If desired, label with additional stains, such as Hoechst, PI, or an antibody, 9. If desired, fix or embed cells, 10. Analyze with a fluorescence microscope, fluorescence plate reader, or flow cytometer. FAM-FLISP excites at 488 nm and emits at 520 nm.
