Lifetech ECR1640 is a styrene/DVB copolymer functionalized with quaternary amines. It is used for enzyme immobilization by ionic interaction, and is particularly suitable for immobilization of enzymes with iP or 3 - 5, like many glycosidases.

Principal Applications

  • Ionic immobilization of enzymes
  • Ionic interaction of proteins with charged groups on the resin
  • Ionic immobilization requires pH adjustment (resin is supplied at alkaline pH)
  • Optimal for glycosidases immobilization

Advantages

  • Reversible enzyme immobilization
  • Adjustable pH
  • Optimal for packed bed column configuration
  • FDA compliant
  • Medium hydrophobicity

Systems

  • Particularly suitable for column configuration
  • Optimal for applications in food industry
