Ultrasound-accelerated immunoassay, as exemplified by enzyme immunoassay of choriogonadotropin.

Abstract

The rate-limiting step in many solid-phase immunoassays is associated with the slow kinetics of binding of macro-molecular antigen and conjugate to the immobilized phase. We demonstrate that the use of ultrasonic energy to enhance mass transport across liquid/solid interfaces can dramatically accelerate antigen binding to immobilized antibodies. We use an… (More)
