Tokyo, Japan—Tosoh Corporation has established analysis technologies for the detection of abnormal cells in the blood and the analysis of cancer-related gene mutations in such cells. In June 2019, Tosoh Analysis and Research Center Co., Ltd. headquartered in Shunan City Yamaguchi Prefecture, launched a contract abnormal cell analysis business through which these technologies will be applied. The new business will serve research institutes and pharmaceutical companies hoping to apply the results in their research.
The following bio-related technologies will be applied through the contract analysis business:
-
Technology to safely preserve blood samples (prevents blood sample degradation during transport)
-
Technology to separate abnormal cells from the majority red blood cells and white blood cells
-
Technology to align and capture cells on a microfabricated chip using dielectrophoresis
-
Technology to detect abnormal cells using anti-C45 antibodies, anti-cytokeratin (CK) antibodies, and nuclear staining agent DAPI
-
Technology for imaging abnormal CK-negative cells based on size and other aspects
Using model samples spiked with human lung carcinoma cell line H1975, these technologies could detect more than 80% of spiked cells as abnormal cells. Additionally, in analyzing cancer-related gene mutations, it is possible to analyze the presence of 50 cancer-related genes in the retrieved abnormal cells using a commercially available gene analysis panel.
Furthermore, the new contract analysis business has the technology to be able to detect both abnormal CK-positive and abnormal CK-negative cells. This will contribute to progress in research into the correlation between the number of CK-positive and CK-negative cells and cancer metastasis.
Meanwhile, Tosoh is proceeding with the development of technologies to separate and detect a variety of cells and molecules. Once the technologies are verified, Tosoh Analysis and Research Center will gradually expand the contract cell analysis business, targeting research institutes and pharmaceutical companies. It will also accelerate research and development activity in its search for marker molecules useful in detecting specific diseases as well as non-invasive and minimally invasive detection technologies. And, through the development of applications in the diagnostic and healthcare fields, it will contribute to helping people live healthy lives.
