Title: The Innovations of Por-Hsiung Lai
Introduction
Por-Hsiung Lai is a notable inventor based in Westlake Village, CA (US). He has made significant contributions to the field of biotechnology, particularly in the area of recombinant proteins. With a total of 2 patents, his work has had a substantial impact on the development of biologically active proteins.
Latest Patents
Lai's latest patents include innovative methods for the control of norleucine incorporation into recombinant proteins. This method involves culturing cells expressing gene products in media with high levels of leucine and/or methionine to inhibit norleucine incorporation. Conversely, norleucine incorporation can be promoted by culturing cells in media that is deficient in leucine and/or methionine or enriched with norleucine. This technique allows for the production of norleucine analogs of important proteins such as IL-2, GCSF, gamma-interferon, and alpha-consensus interferon. Another significant patent focuses on the purification of erythropoietin (EPO) through chromatographic procedures. These methods enable the rapid and efficient isolation of biologically active proteins, particularly glycoproteins like recombinant EPO, from the culture media of genetically transformed mammalian host cells.
Career Highlights
Throughout his career, Por-Hsiung Lai has worked with prominent companies in the biotechnology sector, including Kirin-Amgen, Inc. and Amgen Inc. His expertise in recombinant protein technology has positioned him as a valuable asset in these organizations.
Collaborations
Lai has collaborated with notable colleagues such as Thomas W. Strickland and Dennis M. Fenton. These partnerships have further enhanced his contributions to the field of biotechnology.
