Flow cytometry Anti-bodies Mouse - CD14

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).

Upstream tips
Immortal macrophages, primary bone marrow derived macrophages and DCs or splenic DCs (0.5×106) of the indicated genotypes were treated with E.coli LPS and/or oxPAPC for the indicated time points at 37°C.
Protocol tips
Cells were then washed with 1 mL cold PBS and stained for appropriate antibodies on ice for 20 to 30 min. 2% mouse serum or rat serum were used as the blocking reagent to reduce non-specific binding of the antibodies. The stained cells were then washed with 1ml cold PBS and resuspended in 200 μL PBS.
Downstream tips
Staining of the surface receptors was analyzed with BD FACSCanto II.

Upstream tips
Single-cell suspensions were incubated with a Fc receptor block (1 μg/1 × 106 cells; BD Bioscience, San Diego, CA) to reduce nonspecific anti-body binding.
Protocol tips
Dead cells were excluded using a Live/Dead Fixable Blue Dead Cell Stain Kit (Invitrogen) or 4,6-diamidino-2-phenylindole dihydrochloride (DAPI) (Sigma-Aldrich, St. Louis, MO).
Downstream tips
Flow cytometry was performed using BD LSR II and BD FACS Aria III flow cytometers (BD Bioscience), and data were analyzed with FlowJo software (TreeStar, Ashland, OR).
