Partitioning of Polyethylene Glycol(PEG)-Protein Conjugates in PEG/Dextran Aqueous Two-Phase Systemsystems. At least for bovine serum albumin (BSA) and granulocyte-macrophage colony stimulating factor (GM-CSF) a linear relationship exists between log K of the conjugate and the number of PEG molecules attached to it (up to 20 PEG molecules for BSA and 3 for GM-CSF). The proportionality constant (i

Use of the Aqueous Two-Phase Partition Technique for Characterization and Quality Control of Recombpurification of biological materials.. Aqueous two-phase systems arise in aqueous mixtures of different water-soluble polymers or a single polymer and a specific salt. When two certain polymers, e.g., dextran and polyethylene glycol are mixed in water above certain concentrations, the mixture separa

In the case of particles, the selective adsorption at the interface could also be used for separation in a multistage process such as countercurrentdistribution.. Thus, cells and c

Metal Extraction in Two-Phase Water-Poly(Ethylene Glycol)-Salt Systems,sary to extract highly charged inorganic complex ions or water-soluble organic substances and their complexes with metal ions. Such reagents could extend the sphere of application of liquid-liquid extraction to separation and concentration of inorganic ions. Separation in this case can be based on t

Most water-soluble reagents do not usually form extractable complexes in conventional extraction systems due to the high hydration energy of the species to be extracted. These reagents
