FACS Staining Protocol includes Antibody Staining, Direct staining, indirect staining and intracellular staining. In direct immunofluorescence staining, cells are incubated with an antibody directly conjugated to a fluorophore such as PerCP. This requires only one antibody incubation step and therefore eliminates the possibility of non-specific binding from a secondary antibody. Direct staining is advantageous during intracellular staining because large antibody-fluorophore complexes including secondary antibodies can become trapped and result in non-specific binding, or they may fail to enter the cell which results in no detection.

In indirect staining, the fluorophore conjugated secondary antibody detects the primary antibody which is unconjugated. Another available method is the avidin-biotin system, whereby a biotin-conjugated antibody is detected with fluorophore-labeled avidin.

The Intracellular Staining Protocol allows direct measurement of antigens (cytokines or transcription factors) present inside the cell cytoplasm or nucleus. In this procedure, the fixation and permeabilization of cells are required. Fixing cells will retain the target protein in its original cellular location, and will usually ensure better stability of soluble antigens and antigens with a short half-life. Detecting intracellular antigens requires cell permeabilization before staining, and antibodies should be prepared in permeabilization buffer to ensure the cells remain permeable.

Flow Cytometry Technical Resource Centre – FACS Analysis provides general experimental procedure optimized guide. The resource states that the primary requirement for all types of flow cytometry analysis is that the cells under analysis must be in a single-cell suspension. It is very important to obtain a single cell suspension to avoid clogging up the system with clumps. Peripheral blood mononuclear cells (PBMCs) isolated from whole blood through Ficoll gradient centrifugation, or RBC lysed whole blood, or non-adherent cultured cells are readily applicable for flow cytometry analysis.
