Facsc

Manufactured by BD
Sourced in United States

The BD FACSC is a flow cytometry instrument used for the analysis and sorting of cells and particles in a liquid suspension. It is designed to measure and analyze the physical and fluorescent characteristics of individual cells or particles as they pass through a laser beam. The BD FACSC is a core tool in various research and clinical applications, providing researchers and clinicians with quantitative data on cell populations and their properties.

Cell Cycle and Apoptosis Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
For cell cycle analysis, drug-treated cells with 80% confluence were harvested and fixed with 70% ethanol. Then cells were taken for PI staining and cell cycle was analyzed using flow cytometry. For apoptosis analysis, cells were cultured in attachment, then trypsinized and stained with PI/Annexin V (Vazyme, Apoptosis Detection Kit). Data were collected and analyzed on a BD FACSC and using FACSD via software.

786-O and A-498 cells were seeded into 24-well plates and treated with different concentrations of NCTD (0, 20, 40, or 80 μM) for 24 h. Cells were then harvested and washed with PBS, and stained with FITC-labeled Annexin V/PI Apoptosis Detection kit (BD Biosciences, CA, USA) at dark light for 20 min. Samples were subjected to flow cytometry (FACSCalibur, BD, USA), and data were collected and analyzed on a BD FACSC using FACSD software.

Cell Proliferation and Cell Cycle Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells were cultured in the 96‐well dishes at about density of 5000 cells/well and were detected at the 0, 1, 2 and 3 days. Each well was added with 10 μL CCK‐8 solution and incubated for 3 hours. The OD (optical density) was measured on spectrophotometer at 450 nm wavelength. Flow cytometry assay was utilized to study cell cycle. Cell was harvested and then washed in cold PBS and fixed by cold 70% ethanol overnight. Cell was incubated with PI (propidium iodide) solution on the ice for one half hour. Cell cycle was determined with flow cytometry (FACSC, BD).

Cell apoptosis was analyzed by Annexin V-FITC/Propidium Iodide (PI) Apoptosis Detection Kit according to the manufacturer's protocol (Sigma-Aldrich, Sigma Chemical Co., St. Louis, MO, USA). Briefly, H1299 cells were seeded in 6-well plates at a density of 1 × 104 cells/well and then treated with ZSD (4 mg/mL) for 12, 24, and 48 h, respectively, or different doses of ZSD. Then, cells were collected and centrifuged and resuspended in binding buffer. Afterwards, 5 μL Annexin V-FITC and 5 μL PI were added at room temperature for 15 min. Finally, apoptosis cells were analyzed by a flow cytometer (FACSC, BD Instruments Inc., USA) and FlowJo 7.1.0 software (Tree Star, Ashland, OR, USA).

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.
