Flow cytometry analysis was performed to detect the intracellular BVDV protein, cells were incubated with  anti-BVDV-NS4B antibody and stained with FITC-conjugated anti-mouse IgG antibody. Then, the cells were analyzed using BD FACS Aria™ III High Speed Cell Sorter (BD Biosciences, San Diego, CA, USA).
Apoptosis analysis was performed using the annexin V-FITC double-staining apoptosis detection kit (Beyotime, C1062S) according to the manufacturer’s instructions. Briefly, MDBK cells were infected with NCP BVDV in the presence or absence of siParkin or siNC, the cells were resuspended in 500 μL of 10× binding buffer, then stained with 5 μL of FITC-labelled annexin V and 10 μL of propidium iodide (PI) for 15 min. Subsequently, fluorescence intensity of all staining samples was measured using BD FACS Aria™ III High Speed Cell Sorter (BD Biosciences, San Diego, CA, USA), followed by analysis with FlowJo software, version 10 (Treestar, San Carlos, CA, USA).

RPE Flat-Mounting and FACS Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Mice were euthanized by cervical dislocation. For histological analysis of wholemounts, eyes were prepared as previously described.44 (link) In brief, eyes were enucleated, cleaned, and fixed in fresh 4% paraformaldehyde for 2 h at RT. The cornea, lens, and neuroretina were removed. Eight incisions from the periphery to the optic nerve enabled flat mounting of the tissue with the RPE cells facing upward on a glass slide. For FACS analysis, the enucleated eyes were cleansed and placed in 1% trypsin (Sigma-Aldrich) for 1 h at 37°C. Cells were rinsed off the eyecup using a syringe and a 27-gauge needle with HBSS. The resulting single-cell solution was sorted on a FACSAria III high-speed cell sorter (BD Biosciences, San Jose, CA, USA) using the GFP detector. Cells were initially separated using FSC and SSC as indicated in Figure S5. FSC and SSC doublets were excluded prior to sorting of cells according to detected GFP levels. No cell-specific marker proteins were utilized.

Isolation of eGFP+ Retinal Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Mice were euthanized, and the eyes were enucleated and dissected immediately. The lens, cornea, and neuroretina were removed, and the eyecup was placed in 1% trypsin (Sigma-Aldrich) for 1 hr at 37°C. Cells in the eyecup were rinsed in Hank’s balanced salt solution (Sigma-Aldrich), and the cell population was placed in 1% trypsin for 1 hr to obtain a single-cell solution. The solution was sorted on a FACSAria III high-speed cell sorter (BD Biosciences, San Jose, CA, USA) for sorting of eGFP+ cells. During the sorting, no cells were excluded due to aggregation, size, or debris. The only sorting criterion was eGFP expression.

GFP Expression Analysis by Flow Cytometry

Check if the same lab product or an alternative is used in the 5 most similar protocols
GFP expression in cells transfected with the various reporter plasmids was analysed by flow cytometry using a FACS Canto II cytometer (BD Biosciences). Briefly, viable cells were first gated based on their forward (FSC) and side scatter (SCC) properties. Cell doublets were excluded using FSC‐width vs. FSC‐height. Old cells expressing high levels of GFP were sorted from old cells with low GFP fluorescence (fraction V elutriation) using a FACS Aria III high speed cell sorter (BD Biosciences) with a 70 μm nozzle. Sorting was performed at 4°C. The cut‐off for GFP‐high cells was defined based on cells transformed with an empty control plasmid.

Naïve Tregs were isolated as described previously [12 (link)]. Human CD4+ T cells were stained with cyanine 5–anti-CD4, fluorescein isothiocyanate (FITC)–anti-CD25, and phycoerythrin (PE)–anti-CD45RA. The stained Tregs were sorted on the basis of the CD4+CD25+CD45RA+ T-cell phenotypic markers using a fluorescence-activated cell sorting (FACS) machine (FACSAria III high-speed cell sorter, BD Biosciences, San Jose, CA, USA) and were incubated in OpTmizer CTS T-cell Expansion SFM (Thermo Fisher Scientific Inc., Rockford, IL, USA) containing 2% heat-inactivated human serum (Sigma-Aldrich, St. Louis, MO, USA).

Plasma Microvesicle Profiling by Flow Cytometry

Flow cytometric analysis of plasma MV content was performed according to a recently described protocol [19 (link)] on a BD FACSAria™ III High Speed Cell Sorter (BD Biosciences, San Jose, CA, USA) at a maximal rate of 2 × 104 events per second until 106 events were collected in total. Data processing was performed as demonstrated in Figure 1. A size gate encompassing approximately 100 nm to 1000 nm was established in FlowJo™ software (v. 10.0.8, Tree Star, Inc., Oregon, USA) using the “Autogate” function around 200 nm and 900 nm fluorescent, size calibrated beads on log-scaled forward scatter height (FSC-H), and side scatter height (SSC-H). In addition, a discriminator was set at 200 on SSC-H to avoid exclusion of the smallest events. MVs were defined as phosphatidylserine positive (PS+) events based on binding of lactadherin-FITC within the established size gate. MVs of platelet origin were defined as CD41 positive events; monocyte MVs (MMVs) were defined as CD14 positive events; endothelial MVs (EMVs) were defined as CD62E positive events, and the expression of CD36 was investigated on PMVs, MMVs, and EMVs.

Twelve to 16 weeks after HFD or NCD, splenic CD4+ T cells were isolated by magnetic cell separation (MACS) using the Miltenyi kit. The purified CD4+ T cells were incubated with Fc-block (Thermo Fisher Scientific) followed by staining with CD4-PE-Cy7, CXCR3-FITC, CCR4-PE, and CCR6-APC for 30 min in the dark. All antibodies were obtained from Biolegend (Fell, Germany). Dead cells were excluded by DAPI (BD Biosciences) staining and Th1 cells (CD4+CXCR3+CCR6–) and Th17 cells (CD4+CCR4+CCR6+CXCR3–) were purified using the BD FACS Aria III high-speed cell sorter (BD Biosciences).

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.
