Visualizing ROMK2 and Mitochondria in H9c2 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
The H9c2 WT cells were seeded on a 4-chamber glass bottom dish (Cellvis). After overnight incubation, the cells were transiently transfected with plasmid encoding ROMK2 fused with GFP. Transfection was performed using a Fugene reagent (Promega, Madison, WI, USA). Forty-eight hours after transfection, the mitochondria were additionally stained using 100 nM Mitored (Sigma, St. Louis, MO, USA). Confocal images of living cells were acquired using an Olympus FV 1200.

Visualizing EV Uptake in MeT-5A Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Purified EVs were incubated with PKH67 (Sigma-Aldrich, USA) for 4 min according to recommendations. The labeling reaction was stopped by 0.5% BSA. The mixture was filtrated through a 0.22 μm filter to remove unbound dye. PKH67-labeled EVs were pelleted and resuspended in PBS. MeT-5A cells (2 × 10^4) were seeded in 4-Chamber Glass Bottom Dish (Cellvis, USA), after adherence, 10 μg PKH67-labeled EVs were incubated with MeT-5A cells for 24 h. After being fixed with 4% paraformaldehyde for 10 min, cell skeleton was labeled with TRITC Phalloidin, nuclei were stained with DAPI and the uptake of EVs into MeT-5A cells was visualized by confocal laser scanning microscope.

Transfection and Live-Cell Imaging of U-2 OS Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
U-2 OS cells (ATCC, HTB-96) were maintained in DMEM + GlutaMAX (Sigma-Aldrich, 61965-026) supplemented with 10% FBS at 37°C in 5% CO2. Two days before imaging, the cells were plated onto 4-chamber Glass Bottom Dish (Cellvis, D35C4-20-1.5-N) to achieve 30% confluency. On the following day, the cells were transfected with the mammalian expression vector pcDNA4.0/TO_EGFP-tau or pEGFP-C1_MAP4, or co-transfected with the pcDNA4.0/TO_EGFP-tau and pmScarlet-i alphaTubulin-C1 expression vectors using the HP-Xtreme transfection reagent (Sigma-Aldrich, 636624400). The pmScarlet-i_alphaTubulin_C1 was a gift from Dorus Gadella (Addgene plasmid #85047; http://n2t.net/addgene:85047; RRID:Addgene_85047). The cells were imaged 24h after transfection, with DMEM medium exchanged for FluoroBright DMEM medium (Sigma-Aldrich, A1896701).

The fibroblasts were seeded in a 4‐chamber glass‐bottom dish (Cellvis) and then treated with TGF‐β1 for 48 hours. After fixing with carbinol18 and blocking with 5% BSA, the fibroblasts were incubated with the primary antibodies (ɑ‐SMA, Abcam, ab32575, 1:500) at 4°C overnight and with Cy3‐conjugated goat anti‐rabbit secondary antibodies (1:200, Beyotime Bio, Shanghai, China) at room temperature for 1 hour. The nucleus was labelled with DAPI (Beyotime Bio, Shanghai, China) for 10 minutes. The fibroblasts were imaged with a fluorescence microscope (Olympus, Tokyo, Japan).

MeT-5A cells (2 × 10^4) were seeded in 4-Chamber Glass Bottom Dish (Cellvis, USA), after treatment, cells were fixed with 4% paraformaldehyde for 10 min, permeabilized with 0.1% Triton X-100 for 5 min and blocked with 2% BSA for 30 min. Then cells were incubated with primary antibodies at 4 °C overnight and secondary antibody at room temperature for 1 h and stained with DAPI. A confocal laser scanning microscope was used to observe and take images. Primary and secondary antibodies used were listed in Table S2.

Optically Induced Droplet Formation

Check if the same lab product or an alternative is used in the 5 most similar protocols
The optoDroplet assay was adapted from previous study (Shin et al., 2017) . Plasmids were co-transfected with PEI transfection reagent in 293T cells. For transfection, 293T cell were plated 24 h prior to transduction in 4-chamber glass bottom dish (Cellvis). After transfection, the dishes were cultured in 37 C incubator for 20-24 h. Imaging was performed on Leica SP8 confocal. For global activation and imaging, cells were imaged typically by use of two laser wavelengths. Droplet formation was induced by 488nm light for Cry2 activation with the increasing activation intervals of 10 s, 20 s, 30 s, 40 s, 50 s and 60 s. mCherry imaging was stimulated with 568nm light.

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.
