Protocol Summary

Prepare cells in growth medium

PREPARATION OF STOCK SOLUTIONS

Unless otherwise noted, all unused stock solutions should be divided into single-use aliquots and stored at -20 °C after preparation. Avoid repeated freeze-thaw cycles.

DAX-J2™ PON Green stock solution (400X)

Add 25 µL of DMSO (Component C) into the vial of DAX-J2™ PON Green (Component A), and mix well. Note: 1 µL of reconstituted DAX-J2™ PON Green stock solution is enough for 0.4 mL of cells.

SAMPLE EXPERIMENTAL PROTOCOL

Co-incubate cells with DAX-J2™ PON Green with test compounds in full medium or in your desired buffer at 37°C for desired period of time, protected from light. For control wells (untreated cells), add the corresponding amount of compound buffer. Note: It is recommended to stain the cells in full medium. However, if tested compounds are serum sensitive, growth medium and serum factors can be aspirated away before staining. Resuspend cells in 1X Hank’s salt solution and 20 mM Hepes buffer (HHBS) or the buffer of your choice after aspiration. Alternatively, cells can be stained in serum-free media. We co-incubated Jurkat cells with 200 µM SIN-1 and DAX-J2™ PON Green in full medium at 37°C for 1 hour to induce peroxynitrite. See Figure 1(A) for details.
Alternatively, stain cells with DAX-J2™ PON Green at 37°C for 1 hour, protected from light. Remove the working solution, then treat cells with test compounds in full medium or in your desired buffer at 37°C for desired period of time. See Figure 1(B) for details.
Monitor the fluorescence intensity at FITC channel (Ex/Em=490/530 nm) using a flow cytometer. Gate on the cells of interest, excluding debris.

Images

Figure 1. Detection of peroxynitrite in Jurkat cells upon SIN-1 treatment using AAT Cell Meter™ Fluorimetric Intracellular Peroxynitrite Assay Kit (Cat#16317). (A) Jurkat cells were co-incubated with DAX-J2™ PON Green and 200 µM SIN-1 in full medium at 37 ºC for 1 hour. (B) Cells were stained with DAX-J2™ PON Green for 1 hour, washed with PBS and then incubated with 200 µM SIN-1 in full medium at 37 ºC for 16 hours. Cells stained with DAX-J2™ PON Green but without SIN-1 treatment were used as a control. Fluorescence intensity was measured using ACEA NovoCyte flow cytometer in FITC channel.
