Application of immunoassay and by Oahu initiative Tay protein hydrophobic groups in derivatized poly to immobilized for separation (ethylene imine)

摘要

A member of a bioaffinity binding pair is immobilized on a plastic surface by coating the surface with poly(ethyleneimine) derivatized with a hydrophobic group, and covalently coupling the member to the coated surface. The immobilized member may be used in immunoassays or bioaffinity separations. The derivatized poly(ethyleneimine) is preferably tosyl poly(ethyleneimine).
