Toray Research Center Enhances Drug Discovery with New Analysis System

Advanced Quantification of Biomolecules in Drug Discovery

Toray Research Center (TRC), located in Chuo-ku, Tokyo, has pioneered the introduction of a cutting-edge analysis system that combines nanoflow liquid chromatography and high-resolution mass spectrometry. This innovative capability marks the first implementation of such technology by a domestic analysis company, greatly enhancing the ability to quantify biomolecules like proteins and peptides in extremely low concentrations.

Importance of High-Precision Analysis

The increasing diversification of therapeutic modalities such as antibody drugs and peptide medicines has raised the demand for precise quantification methods applicable to biomolecules, which include mid-sized and large molecules. These biomolecules often exhibit intricate structures and behaviors, making high-resolution and sensitive analytical technologies essential, especially for detecting trace components in biological samples. In drug efficacy evaluations and safety assessments, reproducible and accurate quantification of low-abundance substances is crucial. Traditional analysis systems have faced limitations in detecting low-concentration components due to inadequate signal intensity.

The Value of the Newly Introduced System

TRC's new system integrates advanced separation capabilities from nanoflow liquid chromatography with high-precision measurements offered by high-resolution mass spectrometry. This combination enables the high-accuracy quantification of trace components within complex biological samples, setting a new standard for domestic analysis companies. Previously, sensitivity and separation performance had hindered the detection and quantification of low-concentration components in biological samples. The new system represents a significant improvement, delivering a consistent analytical platform capable of addressing a wide range of molecular types from low to high molecular weights.

Comparison with Traditional Systems
