Title: Yasushi Kasahara: Innovator in Biological Measurement Techniques
Introduction
Yasushi Kasahara is a prominent inventor based in Tokyo, Japan, known for his significant contributions to the field of biological measurement techniques. With a total of 14 patents to his name, he has developed innovative methods that enhance the accuracy and sensitivity of clinical tests.
Latest Patents
Among his latest patents, Kasahara has introduced a method of measuring biological ligands by utilizing amylase. This invention focuses on measuring a biological ligand in a sample containing amylase derived from higher animals. The method employs a combination of an additional amylase not present in the sample, along with an antibody against the ligand or a ligand capable of reacting with the antibody. It also incorporates an amylase inhibitor that exhibits stronger inhibitory activity against the sample's amylase. This innovative approach is particularly suitable for clinical tests aimed at determining physiological substances and trace components in humoral fluids such as serum.
Another notable patent is a method of measuring biological ligands using enzymes. This method is designed to be highly sensitive and specific, making it ideal for clinical tests that determine physiological substances and trace components in humoral fluids. It utilizes a conjugate of an enzyme that acts on a water-insoluble macromolecular substance and an antibody against the ligand to be measured. The steric hindrance of the conjugate is emphasized through the enzyme reaction at the boundary between solid and liquid phases.
