Heme choline esters and uses thereof

Abstract

Methods of activating an apo-peroxidase are provided. The methods include the steps of providing a solution comprising an apo-peroxidase and a heme choline ester, hydrolyzing the heme choline ester with a choline esterase, and converting the apo-peroxidase to active peroxidase. The methods disclosed herein also provide for detecting the presence of an analyte in a sample. The methods include providing a binder capable of specifically binding the analyte wherein the binder is attached to a solid surface, applying the sample to the solid surface under conditions that permit binder-analyte binding, adding a choline esterase-conjugated binder that binds to the analyte, adding an apo-peroxidase, a heme choline ester, a peroxide, and a peroxide-activated signal generator, and detecting the signal produced by the peroxide-activated signal generator. An associated kit and components are also provided.
