Description of MitoPeDPP

MitoPeDPP is a novel fluorescent dye that, due to its triphenylphosphine structure, can penetrate the cell membrane and aggregate in mitochondria.
MitoPeDPP, which aggregates on the inner membrane of mitochondria, can be oxidized by lipid peroxides and release strong fluorescence. Due to the excitation and emission wavelengths of oxidized MitoPeDPP (Ox MitoPeDPP) being 452 nm and 470 nm, respectively, the light damage and spontaneous fluorescence of the sample can be reduced. Therefore, using a fluorescence microscope MitoPeDPP can detect lipid peroxides in living cells.

Protocol of MitoPeDPP

Detection principle
MitoPeDPP can cross cell membranes and accumulate in mitochondria. MitoPeDPP accumulated on the inner mitochondrial membrane can be oxidized by lipid peroxides and release strong fluorescence.

MitoPeDPP


1. Example of co-staining with MitoPeDPP and mitochondrial staining reagent MitoBright

Adding t-BHP (tert-butyl hydroperoxide) to HeLa cells to detect lipid peroxides

Wavelength (wavelength/band pass)

MitoPeDPP: 470/40 (Ex), 525/50 (Em)

MitoBright DeepRed: 600/50 (Ex), 685/50 (Em)

The results confirmed that MitoPeDPP fluoresces after being oxidized by t-BHP in the mitochondria of HeLa cells. In addition, through co-staining with mitochondrial staining reagent (MitoBright Deep Red: MT08), it was confirmed that the fluorescence of MitoPeDPP is localized in mitochondria.

2. Detect lipid peroxides produced by adding Rotenone

After adding MitoPeDPP to HeLa cells [μ-slide, 8-well (manufactured by Ibidi)], add Rotenone solution and observe using a fluorescence microscope. Experimental results confirmed that after adding Rotenone, the production of lipid peroxides in cells was detected.

Rotenone stimulation time: 0 min (left), 90 min (middle), 180 min (right)

3.Experimental example of using MitoPeDPP on nerve cells

A. Fluorescence microscopy detection

Isoflavin was added to NIE-115 cells (mouse neuroblastoma) to induce Ca2+ influx into the cells, and the production of lipid-soluble peroxides in the mitochondrial membrane was observed by fluorescent staining with MitoPeDPP. The experimental results confirmed that the experimental group added with isomycin had stronger fluorescence than the control group.

B. Comparison of average fluorescence intensity data

To quantify the fluorescence intensity of control cells and cells with added ionomycin, a comparison of the two sets of data was performed based on the mean fluorescence intensity.

The results confirmed that the fluorescence intensity observed in the cells 30 minutes after adding ionomycin was significantly increased compared to the cells in the control group.

4. Selectivity of MitoPeDPP reaction

In cell-free reaction systems, MitoPeDPP can react with various peroxides such as H2O2, t-BHP and ONOO-, but in cells, accumulation

MitoPeDPP accumulated in mitochondria can be oxidized by t-BHP to release strong fluorescence (Figure 3A), but reacts only weakly with other ROS or RNS (Figure 3B).

A) MitoPeDPP was added to HepG2 cells and cultured for 15 min, then treated with 100 μmol/l t-BHP.

B) Add MitoPeDPP to HepG2 cells and culture for 15 minutes, then add ROS and RNS inducers.

Add 100 μmol/l (H2O2, NO and ONOO-inducer) and 10 μmol/l PMA (O2-.inducer) respectively.
