Purification of phospholipase D by two-phase affinity extraction
An aqueous two-phase system of polyethylene glycol (PEG)–salt was used for purification of phospholipase D (PLD) from peanuts and carrots. Alginate, a known macroaffinity ligand for PLD, was incorporated in the PEG phase ...
κ-Carrageenan as a new smart macroaffinity ligand for the purification of pullulanase
κ-Carrageenan is a polysaccharide from red seaweed which gets precipitated by K+ ions and dissolves again in water. This smart, K+-responsive polymer was found to selectively bind pullulanase activity from Bacillus ...
