摘要	R-phycoerythrin was isolated and purified from Gracilaria verrucosa on an expanded-bed adsorption column combined with ion-exchange chromatography, which can effectively solve the problem of blockage of chromatographic columns due to polysaccharides during isolation and purification of phycobiliproteins. 0.1 M (NH4)(2)SO4 proved best to elute R-phycoerythrin from the expanded-bed column, and desalted 0.1 M (NH4)(2)SO4 eluate was used on an ion-exchange column to purify the R-phycoerythrin. Using this two-stage chromatography, the purity (OD565/OD280) of the R-phycoerythrin from G. verrucosa is increased to 4.4, and the yield of purified R-phycoerythrin can reach 0.141 mg . g(-1) of the frozen alga.; R-phycoerythrin was isolated and purified from Gracilaria verrucosa on an expanded-bed adsorption column combined with ion-exchange chromatography, which can effectively solve the problem of blockage of chromatographic columns due to polysaccharides during isolation and purification of phycobiliproteins. 0.1 M (NH4)(2)SO4 proved best to elute R-phycoerythrin from the expanded-bed column, and desalted 0.1 M (NH4)(2)SO4 eluate was used on an ion-exchange column to purify the R-phycoerythrin.
