Sugar chains play an important role in biological activities. After nucleic acids and proteins, sugar chains have been described as the third chain of life. TCI intends not only to expand its lineup of basic reagents for sugar chain research by fusing organic synthesis with biotechnology, but also to work towards the development of even more unique and high value added sugar chain related products and applications.

Please make use of TCI’s sugars in Glycoscience.
