Facs scan flow cytometry

Manufactured by BD
Sourced in United States

FACS scan flow cytometry is a laboratory instrument used for analyzing and sorting cells or particles in a fluid sample. It measures multiple physical characteristics of individual particles, such as their size and internal complexity, as the particles pass through a laser beam.

4 protocols using facs scan flow cytometry

1

Annexin V-FITC Apoptosis Assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
An annexin V-fluorescein isothiocyanate (FITC) apoptosis detection kit (Becton-Dickinson, CA, USA) was used to assess apoptosis. After experimental treatments, ARPE-19 cells were collected and suspended in 1× binding buffer containing annexin V-FITC and propidium iodide (PI) according to the manufacturer instructions. Fluorescence was measured with a FACS scan flow cytometry (Becton-Dickinson, San Jose, CA, USA).

Measuring Intracellular Calcium Levels

Check if the same lab product or an alternative is used in the 5 most similar protocols
The cell-permeable calcium-sensitive fluorescent dye Fluo-3/AM (Beyotime, Haimen, China) was used to test the free cytosolic calcium levels. Cells were washed with PBS, and then were incubated with 5 μM Fluo-3/AM at 37°C for 1 h in the dark after the treatment with TG and propofol for 12 h. Then cells were washed with PBS for 3 times and fluorescence of Fluo-3 combined with cytosolic calcium was analyzed by FACS scan flow cytometry (Becton-Dickinson, San Jose, CA, USA).

Monitoring MMP Alteration by Flow Cytometry

Check if the same lab product or an alternative is used in the 5 most similar protocols
The alteration of MMP was monitored by flow cytometry as previously described by Chen et al (30 (link)). The cells were harvested and washed twice with PBS. All samples were stained with DiOC6 (40 nM) for 30 min at 37°C and the fluorescence of DiOC6 was analyzed by FACSscan flow cytometry (BD Biosciences), using CellQuest software (version 5.1; BD Biosciences).

Cell Cycle Analysis by BrdU and DNA Content

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cell cycle was analyzed by determining bromodeoxyuridine incorporation compared with DNA content. A total of 3 × 105 cells were initially plated into a 60-mm plate. The following day, drugs at indicated concentrations were added into the cell medium. After the indicated time, cells were processed according to the manufacturer’s protocol (BD Biosciences). Cell cycle was also analyzed by DNA content. Cells with or without treatment were trypsinized and fixed with 70% ethanol at −20°C overnight. DNA was labeled with propidium iodide (BD Bioscience) at 37°C for 15 minutes. Approximately 10,000 cells were collected for each assay and analyzed using FACS Scan flow cytometry (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.
