Title: Paul R. Carey: Innovator in Insecticidal Protein Research

Introduction

Paul R. Carey is a notable inventor based in Ottawa, Canada. He has made significant contributions to the field of biotechnology, particularly in the identification and purification of insecticidal proteins. With a total of 2 patents, his work has implications for agricultural pest control and environmental sustainability.

Latest Patents

Carey's latest patents focus on the identification, quantitation, and purification of insecticidal proteins derived from Bacillus thuringiensis genes. The first patent describes a process for generating daughter toxins from protoxin-containing materials through limited proteolysis. This process involves using a proteolytic enzyme in an aqueous suspension with a pH above 9.5. The daughter toxins are then separated using high-performance anion-exchange liquid chromatography at a constant pH exceeding 10, employing a salt gradient, typically sodium chloride. This method allows for the qualitative and quantitative characterization of the original mixture and the isolation of individual toxins. It also facilitates the screening and testing of new Bacillus thuringiensis isolates and the monitoring of gene expression levels.
