Amino acids partitioning in aqueous two-phase system of polypropylene glycol and magnesium sulfate

A green method for extracting molybdenum (VI) from aqueous solution with aqueous two-phase system without any extractant

“…The APTS have been widely used in extracting and separating bioactive substance [10][11][12], organic small molecule [13][14][15] and metal cations [16][17][18][19]. However, only a few outcomes have been reported in the extraction and separation of metal anion by ATPS.…”

Application of aqueous mixtures of polypropylene glycol or polyethylene glycol with salts in proteomic analysis

“…Partitioning of some amino acids was also investigated in aqueous two-phase system of PPG425 + MgSO 4 + H 2 O [21]. Application of these systems as a novel prefractionation method used in proteomic analysis and protein purification is considered in the present research work.…”

Partitioning of l-methionine in aqueous two-phase systems containing poly(propylene glycol) and sodium phosphate salts

“…Some research groups have been employed successfully this model to correlate amino acids partitioning in aqueous two phase systems [13][14][15]19]. In this model, the short-range term of the excess Gibbs free energy is given by 1000 n w Á M w :…”

“…In other researches, the partitioning behavior of some amino acids such as cysteine, phenylalanine, methionine, lysine, glycine, and glutamic acid have been also studied in ATPS composed of polyethylene glycol and potassium phosphate salts by some research groups [9][10][11][12]. In our previous work partitioning behavior of three amino acids, alanine, valine and leucine, in aqueous two-phase systems formed by polypropylene glycol (PPG) and magnesium sulfate salt have been studied [13]. The partitioning behavior of three other amino acids, L-phenylalanine, L-tryptophan and L-tyrosine, have been also investigated in two different types of polymer-based and surfactant-based ATPS by our research group [14,15].…”
