Visualizing Lipids and Mitochondria in Neonatal Mouse Cardiomyocytes

Check if the same lab product or an alternative is used in the 5 most similar protocols
Neonatal mouse cardiomyocytes were washed with 1 ml of PBS to remove the medium. The cells were incubated with 200 nM MitoTracker (Sigma) stain for 20 min in the dark at room temperature. The cells were washed with 1 ml of PBS three times. The cells were fixed with 4% paraformaldehyde for 20 min. Then, the cells were incubated with 2 μM BODIPY 493/503 (Sigma) staining solution in the dark for 20 min at 37 °C. The cells were washed using 1 ml of PBS to remove the staining solution. Finally, the nuclei were stained with Hoechst 33258 (Sigma) for 5 min. The cells were observed and photographed by fluorescence microscopy (Olympus IX83). Quantification analysis of lipid contents and mitochondria was performed using Image-Pro Plus 6.0 (Media Cybernetic Inc., USA) image analysis software.

Mitochondrial Dynamics in Oocyte Maturation

Check if the same lab product or an alternative is used in the 5 most similar protocols
Activated mitochondria were imaged with 0.1 µM MitoTracker (Invitrogen, M7512, China), a cell‐permeable potential‐sensitive fluorescent mitochondrial dye emitting in the red (561 nm excitation, 590 nm emission) channel, which had a high affinity with higher potential mitochondria, by using a time‐lapse confocal laser microscope (UltraVIEW‐VoX; PerkinElmer, USA). The GV oocyte meiotic maturation was conducted by incubation in an M2 medium (M7167, Sigma‐Aldrich, USA) containing 0.1 µM MitoTracker.

Mitochondrial Imaging in Cultured MSCs

Check if the same lab product or an alternative is used in the 5 most similar protocols
MitoTracker (Sigma-Aldrich, St. Louis, MO, USA) was used to observe mitochondria in cultured MSCs. The cells were incubated with MitoTracker (10 nM) for 15 min. After washing with PBS twice, these cells were suspended in 500 μL PBS, and were used to detect the mitochondrion ratio per cell by using FACS (Sysmex, Kobe, Japan). Cell forward scatter levels indicating MitoSOX™ positive cells were analyzed using Flowing Software (De Novo Software, Los Angles, CA, USA).

Mitochondrial Dynamics in PINK1-KO Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
TUFm +/À and pink1-KO cell lines were treated with CCCP or DMSO for 0, 2, 4, 6, 8, 10 h and then conducted western-blot analysis with anti-NDUFS3 (Abcam, ab14711, clone 17D95) and anti-Tubulin (DSHB, AB2315513). Moreover, mitochondrial contents in control or pink1-KO HeLa cells were also visualized with Mito Tracker Red (Molecular Probes) using a Leica SP5 confocal microscopy. Cells were co-transfected with GFP and indicated plasmids for 48 h and then treated with CCCP (Sigma-Aldrich, C2759) or DMSO for 8 h following stained with Mito Tracker for 30 min. Finally, the mitochondrial content were assessed with Mito-Morphology Macro in ImageJ as previously described (Dagda et al., 2009) . More than 30 randomly selected individual cells were analyzed for each data point. Three biological replicates were performed.

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.
