Title: John C Edwards: Innovator in Assay Methods

Introduction

John C Edwards is a notable inventor based in Little Kingshill, GB. He has made significant contributions to the field of assay methods, holding a total of 2 patents. His work focuses on improving the efficiency and accuracy of assays used in various applications.

Latest Patents

One of his latest patents is titled "Method of performing assay for analyte in liquid medium." This invention involves assays, such as immunoassays or two-site immunometric assays, that utilize a labelled reagent and another reagent bound to magnetically attractable particles. These particles are suspendable but insoluble in a liquid assay medium. The method allows for the partitioning of the labelled reagent between the liquid phase and the particles, depending on the analyte concentration in a sample. After partitioning, the liquid phase is removed, and the particles are re-suspended in another liquid medium for concentration observation. This method is particularly suitable for fluorescent and chemiluminescent label systems and can be conveniently performed in microtiter plates.

Another significant patent by Edwards is "Immunoassay with chromatographic medium and labelled reagent." This method involves providing a chromatographic medium, preferably in sheet form, and forming a reaction mixture containing a labelled reagent. The mixture is applied to a spot on the chromatographic medium, and the label intensity remaining at the spot is measured. This method offers a convenient way to perform immunoassays, two-site immunometric assays, and agglutination assays.
