The remaining cell pellet was then incubated with the antibody mix anti-CD14 Phycocyanin 5 (PC5)/anti-CD33 PC5 for 20 min at 4[degrees]C in darkness, followed by erythrocyte lysis and leukocyte fixation via incubation with 1 mL fluorescence-activated cell-sorting (FACS) lysing solution for 15 min.
The presence of the phycobiliprotein phycocyanin was confirmed by the fluorescence method of Stewart & Farmer (1984), thereby placing the isolate unequivocally in the cyanobacteria; this fluorescence spectrum was identical to that of Synechococcus sp.
