| 中文摘要 | the partitioning behavior of four amino acids, cysteine, phenylalanine, methionine, and lysine in 15 aqueous two-phase systems (atpss) with different polyethylene glycol (peg) molecular weights and phosphate buffers has been studied in the present paper. the phase diagrams of the systems are investigated together with the effect of the peg molecular weight and ph of the phosphate solutions. the composition of these systems and some parameters such as density and refractive index are determined. the influences of salts in atpss, side chain structure of the amino acids, ph of atpss, and the peg molecular weight on the distribution ratios of the amino acids have been studied. this work is useful for the purification of amino acids and the separation of some proteins whose main surface exposed amino acid residues are these four amino acids, respectively. |
