Title: The Innovative Contributions of John O Naples
Introduction
John O Naples is a notable inventor based in Dresher, PA (US). He has made significant contributions to the field of cell culture and ion exchange resins, holding a total of 4 patents. His work has advanced the understanding and application of nonanchorage-dependent cells, which are crucial for various biotechnological applications.
Latest Patents
One of his latest patents focuses on the immobilization of nonanchorage-dependent cells. This innovative method involves contracting an aqueous suspension of these cells with a floc formed by combining positively and negatively charged ion exchange resins. The particle sizes of these resins range from about 0.01 to about 1.5 microns. The flocs can be formed either before contact with the cells or in situ within the cell suspension. This process allows for the effective use of resin flocs as microcarriers for the cells. Another significant patent involves the development of low-rinse, high-capacity, weakly basic acrylic ion exchange resin. This invention utilizes copolymers of acrylonitrile with aliphatic cross-linkers, which are functionalized with polyamines to create anion exchange resins that require low rinse volumes while maintaining high anion exchange capacity.
