- Prepare samples and controls.
- Dilute 10X Injection Buffer 1:10 with 45 mL diH20.
- Reconstitute SR-FLIVO with 50 µL DMSO.
- Dilute SR-FLIVO 1:12 with 550 µL 1X Injection Buffer.
- Inject 100 µL intravenously.
- Let SR-FLIVO circulate 30-60 minutes.
- View live tumor through a window chamber using a fluorescence microscope.
- If not viewing directly, excise tissue.
- If desired, label with additional stains, such as Hoechst 33342, or an antibody.
- If desired, fix cells.
- Analyze with a fluorescence microscope, flow cytometer, or a window chamber system. SR-FLIVO excites at 550-580 nm and emits at 590-600 nm.

"The body weight of the mice was monitored twice weekly. To assess intratumour caspase cleavage, FLIVOTM in vivo apoptosis tracers (Immunochemistry Technologies LLC, MN, United States) were used. The SR FLIVOTM red dye was prepared according to the manufacturer’s protocol and 100 μl was injected into the tail vein of mice after appropriate treatments were completed. After 1 h, whole tumors were excised, digested and analyzed using flow cytometry on the BD FACSAria I."
