Title: Paul K Cartier, III: Innovator in Protein Sequencing Technologies

Introduction

Paul K Cartier, III is a notable inventor based in Arcadia, CA, who has made significant contributions to the field of protein sequencing. With a total of four patents to his name, Cartier has developed innovative methods that enhance the efficiency and accuracy of protein analysis.

Latest Patents

One of Cartier's latest patents is a method for compositional tag sequencing. This technique utilizes a modified Edman degradation process to obtain compositional tags for proteins. By separating the Edman degradation chemistry from amino acid analysis, Cartier's method circumvents the serial requirements of the conventional Edman process. Multiple cycles of coupling and cleavage are performed prior to the extraction and compositional analysis of amino acids. The resulting amino acid composition information is then used to search a database of known protein or DNA sequences to identify the sample protein.

Another significant patent is the method of sequencing peptides and proteins using a valve block assembly. This method provides a novel approach for sequencing by supplying coupling and cleavage reagents through a valve block assembly with internal delivery channels and a common outlet channel. The outlet channel communicates with a reaction chamber where the sample is placed. Access to the delivery channels is controlled by diaphragm valves, which are designed to minimize exposure of plastic tubing to oxygen, thereby reducing the risk of oxidative decomposition and cross-contamination of reactants.

Career Highlights

Throughout his career, Cartier has worked with reputable companies such as Porton Instruments, Inc. and Beckman Coulter, Inc. His experience in these organizations has contributed to his expertise in the field of protein sequencing and analysis.
