Quantification and purification of phycobiliproteins
The quantity of phycobiliproteins and purity index (PI) were found to differ in both crude and membrane filtered fractions obtained using different solvents such as phosphate buffer (pH 6.8), distilled water (pH 7.0) and seawater (pH 8.13). The absorption peaks (λmax) of phycobiliproteins were also found to vary in the visible regions
