Tokyo, Japan— Tosoh launched two kinds of immunoassay reagents that detect antibodies to nucleocapsid protein (NP) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on December 2, 2020 for the Japan market. The product names for the Japan market are AIA-CL SARS CoV-2 NP-total antibody reagent and AIA-CL SARS CoV-2 NP-IgG antibody reagent. Please note that the overseas product names are subject to change.*
These reagents detect IgG and total antibodies (including IgG and IgM) against NP of the SARS-CoV-2, respectively. Both reagents are for use with Tosoh’s automated chemiluminescence enzyme immunoassay analyzers AIA®-CL2400 and another model of the AIA-CL analyzers. These two reagents require no manual preparation before use and offer results in as little as 15 minutes. They are expected to contribute to basic and clinical studies of SARS-CoV-2.
The research and development of these reagents was a result of collaborative effort by Tosoh, Yokohama City University, and Kanto Chemical Co., Inc., and was subsidized by the Japan Agency for Medical Research and Development (AMED). AMED supported this R&D under its fiscal year 2021 project as part of its research projects as countermeasures against infectious diseases such as viruses.
Tosoh is also working with Yokohama City University and other external entities on the R&D of a SARS-CoV-2 antigen test for its AIA-CL series analyzers. As ever, Tosoh aims to contribute to furthering medical research and practices.
*The two reagents referred to in this press release are for research use only. Their performance in clinical use have not been established. These reagents, therefore, are not to be used for diagnostic or treatment purposes.
