Title: Chester L. Sutula: Inventor in Immunoassay and Insecticide-Resistance Testing.

Introduction

Chester L. Sutula is an inventor associated with Elkhart, Indiana. His work includes inventions for detecting microorganisms and assessing insecticide resistance. His patent portfolio includes 2 patents.

Latest Patents

Sutula’s patent titled “Immunoassay and Method of Use” describes a method for detecting microorganisms that produce extracellular polysaccharides (EPS), lipopolysaccharides (LPS), or both. In a preferred approach, cetyltrimethylammonium bromide (CTAB) extracts these substances from a sample, after which they bind preferentially to colored polystyrene latex particles. A lateral-flow immunoassay then detects the bound material using antibodies specific to the EPS or LPS. The method may also be used to detect certain viruses, including members of the Potyviridae and Tobamoviridae groups.

His “Insecticide Resistance Assay” patent describes methods for identifying insect species and assessing their resistance to pesticides. The methods use feeding disruption caused by insecticides, including the biopesticide toxin Bt, and can evaluate resistance in individual insects or insect populations. The invention also covers monitoring resistance, screening compounds for insecticidal activity, and assay-related apparatus and dehydrated insect-meal pads.
