Flow cytometry Anti-bodies Human - CD27

Flow cytometry is an immunophenotyping technique whereby sing cell suspensions are stained for either cell surface markers or intracellular proteins by fluorescently-labelled antibodies and analyzed with a flow cytometer, where fluorescently-labelled molecules are excited by the laser to emit light at varying wavelengths, which is then detected by the instrument. There are several key criteria which are required to be kept in mind while designing a flow experiment- 1. Antibody titration (optimal dilution of antibodies should be calculated in order to avoid over- or under- saturated signals for proper detection of surface and intracellular markers), 2. Precision (3 or more replicates of the sample should be used per experiment), 3. Specificity (proper isotype controls should be included in the experiment), 4. Day-to-day variability (experiments should be repeated 3 or more times to ensure consistency and avoid variability due to flow cytometer settings), 5. Antibody interaction (Fluorescence minus one or FMO should be used, which is the comparison of signals from panel minus one antibody vs. the full panel), and 6. Antibody stability (fluorescently-labelled antibodies should be stored at 4C).

Protocol tips
For the ex vivo immunophenotyping experiments, frozen samples were used and were thawed in R10 supplemented with 20 µg/ml DNase I from bovine pancreas (Sigma-Aldrich). After extensive washing with PBS (Sigma-Aldrich), the cells were stained immediately with the Zombie Aqua Fixable Viability kit (BioLegend) for 15 min at room temperature. Then, the cells were washed and stained with the combination of mAbs for 30 min at 4°C.
Downstream tips
All data were acquired on a FACS Symphony A5 flow cytometer (BD Biosciences) equipped with five lasers (UV, 350 nm; violet, 405 nm; blue, 488; yellow/green, 561 nm; red, 640 nm; all tuned at 100 mW, except UV tuned at 60 mW) and capable to detect 30 parameters. Flow cytometry data were compensated in FlowJo by using single stained controls (BD Compbeads incubated with fluorescently conjugated antibodies)

Protocol tips
cells were transferred, centrifugation at 1500 g for 10 min and incubated with antibodies for 20 min at 37 °C. Annexin V was then added and stained for 15 min at room temperature.
Downstream tips
After incubation, BMMCs were washed, centrifuged, measured by a FACSCanto II (BD Biosciences) and resulting data were analysed using FlowJo software.
