摘要：

Affinity partitioning of lactate dehydrogenase (LDH) was studied in polyethylene glycol (PEG)/salt and PEG/hydroxypropyl starch (PES) aqueous two-phase systems, using free triazine dyes as their affinity ligands. The free dyes showed one-sided partition to the top PEG-rich phase and thus enhanced the affinity partitioning effect in the systems. A two-step affinity extraction process has been discussed for large scale purification of LDH from rabbit muscle.
