Title: Kathryn Irene Stilwell: Innovator in Serological Testing

Introduction

Kathryn Irene Stilwell is a notable inventor based in Woodlawn, California. She has made significant contributions to the field of serological testing, particularly in the detection of paratuberculosis. Her innovative approach utilizes fluorescence polarization technology to enhance the accuracy of diagnostic assays.

Latest Patents

Stilwell holds a patent for a "Rapid serological test for paratuberculosis using fluorescence polarization technology." This invention provides an assay for the detection of serum antibodies. A tracer, which comprises a carbohydrate antigen isolated from the pathogen, is conjugated to a fluorophore and added to a serum sample from an animal. The fluorescence polarization of the mixture is then measured. The presence of serum antibodies is indicated by a fluorescence polarization value that is higher than that of a control. This invention further includes a tracer designed for use in a fluorescence polarization assay for antibodies specific to the pathogen, allowing for a detectable change in fluorescence polarization.
