Evaluating Lipid Peroxidation via Flow Cytometry and Confocal Microscopy

Check if the same lab product or an alternative is used in the 5 most similar protocols
Lipid peroxidation was analyzed by flow cytometry and confocal laser-scanning microscope. For flow cytometry analysis, cells were plated in six-well culture plate overnight and then treated with indicated agents. Next, cells were incubated with 10 μM BODIPY 581/591 C11 (Thermo Fisher, D3861) for 30 min, washed with PBS, trypsinized and resuspended in PBS, and then subjected to flow cytometry analysis. For confocal imaging, cells were seeded in a 4-chamber glass bottom dish (Cellvis, D35C4-20-1.5-N) and treated as previously indicated. After incubated with 5 μM BODIPY 581/591 C11 for 30 min and washed with PBS, images were acquired using the confocal laser-scanning microscope.

Islets from GKKI and control mice were left to recover overnight in Islet Medium (RPMI 1640, 11mM Glucose, 10% FBS, with Penicillin-Streptomycin 100 IU-μg/ml). On the day of the experiment, 8 islets per group were transferred to a Petri dish with Krebs-Ringer Bicarbonate buffered medium + 10 mM HEPES (KRBH) at pH 7.40, supplemented with + 0.1 % Bovine Serum Albumin and 1 mM glucose. The cell permeant calcium indicator Cal-590 AM (AAT Bioquest, Inc.) was added to the dish at a concentration of 4 μM, and the dish was set on a shaker at room temperature for 30 minutes. Next, the islets were transferred to a 4-chamber glass bottom dish (D35C4–20-1.5-N, Cellvis) containing KRBH with 0.1 % BSA and 1 mM glucose, and the dish was placed in a stage-top incubator set at 37°C, 5% CO2, 100% humidity for the duration of the experiment. Imaging was performed using a Zeiss LSM880 microscope with a Plan-Apochromat 20x/0.8 M27objective, with the following settings: 561 nm laser excitation, 570–695 nm bandpass filter, pixel size 1.661 μm, pixel dwell time 33.0 μs. After each glucose concentration was added, we waited 6 minutes before starting the 5-minute time-course with one image every 5 seconds. For the study of calcium waves across islets, we employed a pixel size of 1.371 μm and a pixel dwell time of 3.45 μs to acquire images every 42 ms.

Then, the media was replaced by 1 µM Hoechst 33342 and 100 nM MitoTracker Deep Red in 400 µL DMEM glutamax containing 1% BSA ± 1 mM Palmitate. After 30 min of incubation at 37 °C, the cells were washed with 400 µL of Live Cell Imaging Solution and replaced by 1 µM DPP-2/500 nM mitoDPP-2 in Live Cell Imaging Solution (Molecular Probes). After 10 min of incubation at 37 °C, images were obtained as described above with the following settings: for DPP-2 (exposure time 150 or 250 ms, EM gain 100 or 150), mitoDPP-2 (exposure time 150 ms, EM gain 75), MitoTracker Deep Red (exposure time 15 ms, EM gain 15), Hoechst 33342 (exposure time 40 ms, EM gain 20), and brightfield (exposure time 100 ms, EM gain 50).

300,000 HEK293T cells/well or 125,000 HepG2 cells/well were plated in four-well chamber slides (D35C4-20-1.5-N, Cellvis) precoated with 5 μg Poly-D-lysine (30-70 KDa, Alfa Aesar). After 20-24 hr, cells were pretreated with 10 μM PalmB, 5 μM ML348, or 2.5 μM mitoFP for 30 min at 37 °C. Control cells were pretreated with vehicle (DMSO). Hoechst 33342 and MitoTracker Deep Red were included for respective nuclear and mitochondrial visualization, as was 2 μM of the mitochondrial-targeted H2O2 probe, mitoPY1 (Sigma). After pretreatment, cells were briefly washed with DPBS, and treated with 100 μM H2O2 in fresh DPBS (400 μL) for 10 min at 37 °C. Control cells were untreated. Cells were then imaged on an inverted epifluorescence microscope. Analyses were performed in ImageJ (Wayne Rasband, NIH). For data analysis, the average fluorescence intensity per image in each experimental condition was obtained by gating cells using the brightfield image and applying that mask in the corresponding mitoPY1 image. All data was normalized to the average fluorescence intensity of the DMSO-pretreated control that was not exposed to H2O2. Each experiment was repeated in at least two biological replicates with identical results.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
