PEG
PEG/Salt Systems PEG-salt two phase system: has been known for some time. Kohler formed 7.5% w/w PEG 1500 and 14% potassium phasphate two phase systems directly in a bioreactor and used…
EOPO
For antibody purification using partitioning see "antibody purification" Many thermoseparating polymers contain ethylene oxide groups. PEG is a thermospearating polymer but its cloud point is too high (above 100C) for use in…
Extraction/partitioning
As to partitioning of antibodies see "purification of antibodies" Extraction is the prcoess of moving one or mroe components of a mixture form one phase to another (compare to precipitation which…
