Process Media


TOYOPEARL AF-Tresyl-650M is an activated resin that is highly reactive toward amine and thiol groups. It is provided in dry form, ready for reaction in buffered solutions containing the ligand to be coupled. Coupling is accomplished in a neutral to slightly alkaline (pH 7 - 8) solution. Under such conditions even proteins of limited stability may be successfully coupled. Coupling leads to the formation of a highly stable secondary amine or thio-ether linkage.
