Title: Kiyoshi Nagai: A Pioneer in Hemoglobin Research and Artificial Blood Substitutes

Introduction:

In the vast realm of scientific research, few names stand out like that of Kiyoshi Nagai. Hailing from Cambridge, GB, Nagai has made substantial contributions to the field of hemoglobin research, particularly in the development of artificial blood substitutes. With numerous patents to his name, Nagai's groundbreaking work has revolutionized the way we understand and utilize hemoglobin. This article delves into his latest patents, career highlights, collaborations, and the impact of his contributions.

Latest Patents:

Kiyoshi Nagai's pioneering research has resulted in a remarkable portfolio of 13 patents, each representing a step forward in the study of hemoglobin and the development of artificial blood substitutes. Two of his most recent patents include:

1. "DNA encoding fused di-alpha globins and use thereof":

This patent introduces the concept of di-alpha globin, a unique molecule assembled by connecting two alpha subunits of hemoglobin. Di-alpha globin can be combined with beta globin and heme to form functional hemoglobin. By utilizing recombinant DNA techniques, Nagai unlocked the potential for expressing di-alpha globin.

2. "Hemoglobins with intersubunit disulfide bonds":

Nagai's second patent focuses on the creation of mutant hemoglobins. He developed cysteine substitution mutants of alpha and/or beta globin to create crosslinked mutant hemoglobins with intersubunit disulfide bonds. These mutant hemoglobins, with reduced oxygen affinity, were explored as blood substitutes. This patent also paves the way for commercial production of wholly artificial hemoglobin.

Career Highlights:

Throughout his illustrious career, Nagai has worked with leading companies in the field of biotechnology. He has made significant contributions at organizations such as Somatogen, Inc. and Baxter Biotech Technology Sarl, where he has been instrumental in advancing the development of innovative hemoglobin-related technologies.
