Stress Granule Formation in U2OS Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
After specified durations of treatment with 0.5 mM sodium arsenite (Sigma-Aldrich) to induce stress granule formation5 (link), wild-type U2OS cells were fixed with 4% formaldehyde for 15 min, permeabilized with 0.1% Triton X-100 in phosphate-buffered saline (PBS) and blocked with 5 mg ml–1 bovine serum albumin (Sigma-Aldrich), in some cases also containing 0.25% Triton X-100. Fixed cells were incubated overnight at 4 °C with primary antibodies (mouse anti-G3BP (1:500, abcam ab56574) and rabbit anti-β-tubulin (1:200, abcam ab6046)) to stain the stress granules and microtubules. Note that G3BP does not co-precipitate in β-tubulin immunoprecipitation and is commonly used as a stress granule marker26 (link),65 (link). Secondary antibodies consisted of rhodamine Red-X anti-mouse IgG (1:500, Jackson ImmunoResearch) and Alexa Fluor 647 anti-rabbit IgG (1:500, Jackson ImmunoResearch). DNA was stained by incubating in 4′,6-diamidino-2-phenylindole (DAPI) (1:500, Sigma) for 15 min at room temperature. Coverslips were mounted in ProLong Gold (ThermoFisher).

Quantifying Mitochondrial Mass by VDAC-1 Staining

Check if the same lab product or an alternative is used in the 5 most similar protocols
Mitochondrial mass was evaluated using anti-VDAC-1 staining quantified by flow cytometry. Briefly, cells were collected and washed with cold phosphate buffer saline (PBS), fixed with 4% PFH, and kept on FACS buffer (PBS, 0.5% BSA, 0.05% Sodium Azide). For staining cells were washed twice with Intracellular Staining Permeabilization Wash Buffer (Biolegend, Catalogue No. 421002), and re-suspended in same buffer with anti-VDAC-1 (1:200, abcam, Catalogue No. 15895) for 30 min at room temperature. Cell samples were washed with wash buffer and incubated secondary (Alexa Fluor® 647 Anti-Rabbit IgG Jackson Immuno Research Laboratories, Catalogue No. 111-605-003) for 30 at room temperature in the dark. After two washes with FACS buffer, cells were re-suspended on FACS buffer and assessed on CytoFLEX flow cytometer (Beckman Coulter, Life Science, Indianapolis, IN, USA). Flow data analysis was performed using FlowJo software.

Tracing iPSCs Differentiation in vivo

NMR iPSCs or EGFP-expressed iPSCs grown on Matrigel were collected by 0.05% trypsin treatment and injected under the kidney capsules into non-obese diabetic (NOD)-SCID (NOD.CB17-Prkdc/J) mice. The kidney capsules were collected 10 weeks after the injection and processed for paraffin embedding and H&E staining or immunofluorescence co-staining with primary polyclonal antibodies against GFP (chicken IgY; Invitrogen; A10262) and TUJ-1(1:500, Covance; MMS-435P). Secondary antibodies were Alexa 488-conjugated anti-chicken IgY (Invitrogen; A-11039) and Alexa Fluor 647 anti-rabbit IgG (1:200 dilution, Jackson ImmunoResearch; 111-607-003). Genomic DNA of kidney capsules was extracted using a DNeasy Blood & Tissue Kit (QIAGEN). PCR with GoTaq polymerase using specific primers to M2rtTA lentiviral vector was performed to confirm the origin of NMR iPSCs in the kidney capsules.

The following antibodies were used for immunofluorescent labeling: anti-claudin-3 (Life Technologies), anti-rabbit IgG-FITC (Vector Laboratories, Burlingame, CA), anti-occludin-AlexaFluor488 (Life Technologies), anti-histone H2A/H4 (BWA3), anti-mouse IgG-TRITC (Jackson Immunoresearch), anti-mouse Ly6G-AlexaFluor647 (eBioscience, San Diego, CA), anti-mouse CD11c-AlexaFluor488 (eBioscience), anti-mouse surfactant A (Millipore), anti-rabbit IgG-AlexaFluor647 (Jackson Immunoresearch). Slides were mounted with ProLong Gold anti-fade reagent containing DAPI (Life Technologies). Digital monochromatic images were acquired on a Nikon A-1 confocal system with Nikon Elements software and pseudocolored. For quantitative analysis of histone-associated cells, greater than 200 histone-associated cells were analyzed per lung (n=3 mice) for cell type-specific labeling (neutrophil, macrophage, or type II alveolar epithelial cells). The percentage of histone-associated cells that were also labeled for the cell type-specific marker is displayed.

Indirect flow cytometry was done to sorting DDR2- and FSP-1-expressing cells isolated from the periosteum. Cells were incubated with the primary antibody DDR2 and FSP-1 for 30 min at 4 °C, followed by staining with fluorescent conjugated secondary antibodies Anti-Rabbit IgG Alexa Fluor 647 (Jackson, Philadelphia, PA, USA) and anti-Rat IgG DyLight 488 (Invitrogen, USA). The cells subjected to flow cytometry without the addition of a primary antibody or secondary antibody served as controls.

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.
