Oxidative stress was also tested through ΔΨm changes based on the fluorescent dye rhodamine 123 (Rh123). For this, cell suspensions (1 × 106) were treated with ZnO NPs (5, 10, 20 μg/cm2) for 1 h. Then, cells were washed with PBS and incubated with Rh123 (5 μg/mL) for 15 min. After incubation, cells were washed with PBS and analyzed in a FACSAria flow cytometer (Becton-Dickinson, CA, USA). Data was processed using FlowJo 8.7 software (Stanford University).
Facsaria flow cytometer
The BD FACSAria flow cytometer is a high-performance cell sorting instrument designed for advanced research applications. It utilizes fluorescence-activated cell sorting technology to accurately identify and separate individual cells from complex samples based on their unique physical and biochemical characteristics.

Annexin V-FITC Apoptosis Assay for Cell Lines
in this series (
externalization, a marker of early apoptosis, was assessed using the
FITC Annexin V apoptosis detection kit (BD Pharmingen, San Jose, CA,
USA) on a BD FACSAria flow cytometer. Following their collection,
the A549 and L929 cells were twice washed in ice-cold PBS before being
resuspended in 100 μL of binding buffer. The cells were treated
with a volume of 5 μL (5 μg/mL) of Annexin V-FITC and
PI, and they were incubated for 15 min at room temperature (20–25
°C) in the dark. Following that, 400 μL of binding buffer
was added to the combination samples, and FACSDiva version 6.1.1 was
used to analyze the samples on a BD FACSAria flow cytometer.
Isolation and Co-culture of Immune Cells
Enrichment and Sorting of CD45+ Semen Cells
CD45+ semen cells from animals #BA865F, #1103075, #CA147F, and #MF1414 were enriched using CD45 magnetic beads and cell sorting with a BD FACS Aria Flow Cytometer. Total semen cells were incubated for 15 min at 4 °C with 20 μl anti-CD45 magnetic beads (Miltenyi Biotec) and washed once with 2 ml cold PBS supplemented with 0.5% BSA and 2 mM EDTA (sorting buffer). The CD45+ cell fraction was then enriched by magnetic-bead sorting, using LS columns (Miltenyi Biotec), according to the manufacturer's instructions. Cells were eluted in 4 ml sorting buffer. Following the magnetic bead-based enrichment process, cells were stained with amine-reactive blue dye (Life Technologies) to identify the dead cells, and anti-CD45 (clone D058-1283, BD Pharmingen). Cells were washed twice and stored at 4 °C in PBS/10% FCS. CD45+ cells were then sorted by simultaneous four-way sorting on a FACS Aria flow cytometer (BD Biosciences). The enriched cell fraction was used in the neutralization assay.

Apoptosis and Cell Cycle Analysis
HFLS-RA cells were harvested 48 h after transfection and fixed with 75% ethanol at −20°C for at least 2 h. Subsequently, cells were resuspended in the PI reagent (BD). Finally, we analyzed the cells in different phases using the FACSAria flow cytometer (BD).

Cell Cycle and Apoptosis Analysis of Drug Treatments
For apoptosis analysis, the cells were treated for 24 h with XAV939 (8 μmol/l), 5-FU (50 μmol/l), XAV939 (8 μmol/l) + 5-FU (50 μmol/l), DDP (8 μmol/l) and XAV939 (8 μmol/l) + DDP (8 μmol/l), separately. The cells were measured using FACSAria flow cytometer (BD Biosciences, USA), and Annexin V (+) cells were counted for apoptotic cells after Annexin V-fluorescein isothiocyanate/propidium iodide (FITC/PI) (BD Pharmingen) double staining. The experiment was performed in triplicate.
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.
