For example, nucleic acid stains such as acridine orange, SYTO 9 stain, and ethidium homodimer-1 will stain only nucleated cells, thereby reducing counting complexity when RBCs and platelets are present. The main difference between BF and FL analysis when counting PBMCs is that fluorescence can provide more selective staining, and thus more accurate counts when dealing with complex samples containing significant amounts of platelets, RBCs, or debris. When considering the fluorescent cell counting options currently available, many users ask which counting method is better, brightfield (BF) or fluorescence (FL)? Both have been used for decades and are trusted analysis methods cited in primary literature.
