Calibration curves of phycobiliprotein standards: phycocyanin (diamonds), allophycocyanin (squares), and phycoerythrin (triangles) obtained for a spectroscopic measurements (Spectrophotometer UV/Vis, Hitachi U-2800) and b–d spectrofluorometric measurements, Fluorescence Spectrophotometer (Cary Eclipse, Varian, Agilent Technologies) for different lamp intensity settings: b 600 V, c 800 V, and d 1000 V. The characteristic wavelengths for which instruments gave the illustrated responses are specified in Table 3
