Title: Ryuji Furuta: Innovator in Human Neutrophil Chemotactic Factor Research
Introduction
Ryuji Furuta is a prominent inventor based in Otsu, Japan. He has made significant contributions to the field of biochemistry, particularly in the study and production of human neutrophil chemotactic factors. With a total of 5 patents to his name, Furuta's work has advanced our understanding of immune response mechanisms.
Latest Patents
Furuta's latest patents include a method for preparing an active human neutrophil chemotactic factor. This innovative approach provides a simple and efficient way to prepare active recombinant human neutrophil chemotactic factor. The method involves solubilizing the human neutrophil chemotactic factor (NCF) from a transformant cell homogenate using urea or guanidine hydrochloride. The polypeptide is then purified using conventional protocols such as CM-Sepharose CL-6B and HW-55 column. This technique allows for the recovery and purification of large amounts of active human NCF. Another notable patent is the process for producing a human neutrophil chemotactic factor peptide, which includes an expression vector containing DNA encoding the NCF polypeptide and a transformant for its production.
