Lifetech ECR8309M/pH4 is a methacrylate polymer functionalised with amino groups on a short spacer (C2). Resin pH is adjusted at 4 for ionic immobilization of enzymes with iP in the range 4-5 (typical for many glycosidases) by interaction of the ionizable surface aminoacids (Lys, Arg, His, Asp, Glu) with the charged amines on the polymer. Lifetech ECR8309M/pH4 main features are the medium porosity, the hydrophilicity and its optimal use in columns.
