Introduction

Toshiya Kawaguchi is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of protein research, holding a total of four patents. His work focuses on the development of novel proteins with specific biological activities.

Latest Patents

Kawaguchi's latest patent involves a novel protein that exhibits inhibitory activity on the protease activity of hepatocyte growth factor (HGF) activator. This protein was purified and isolated, with its molecular weight determined to be approximately 40,000 daltons. The N-terminal and partial amino acid sequences of the protein were also established. A gene coding for this protein was cloned, and the gene DNA was incorporated into a vector for transforming host cells. The cultivation of the transformant resulted in the production of the desired protein. This protein can serve as an in vivo or in vitro control factor for HGF or HGF activator. Additionally, it is useful as an antigen for producing antibodies, which can be employed in kinetic studies of the protein or as a standard in assay systems.
