Tumor-associated Antigens
Carbohydrates play important roles in various biological functions such as cell recognition, cell adhesion, intercellular and intracellular signaling, and embryonic development. Cellular glycosylation profiles significantly change during carcinogenesis. These cellular carbohydrate structures are known as tumor-associated carbohydrate antigens, and they are considered promising targets for immunotherapy as well as developing vaccines and therapeutic antibodies. TCI supports the research in this field with various tools.

The glycomoiety structure of proteins and lipids changes in cancerous cells. For example, N-acetylglucosaminyltransferase V (GnT-V) is expressed at a very low level in normal cells, but is abundant in cancer cells. Due to such changes in the expression levels of glycosyltransferases, the synthesized oligosaccharide chains vary based on the type of cancer cells, and can be used as diagnostic markers.
Cancer cell-specific oligosaccharides play important roles, such as immortalization of cancer cell, cell adhesion / metastases, and abnormal growth. Such cancer cell-specific oligosaccharides are good targets for drug discovery, and these oligosaccharides are being used to develop therapeutic targets, vaccine preparations (using cancer antigens), inhibitors of carbohydrate synthesis, galectins, and selectins, antibody-based drugs targeting oligosaccharide antigens, and chimeric antigen receptor gene modified T cells (CAR-T).

HSA-Oligosaccaride Conjugates
Useful tools for evaluating carbohydrate-binding molecules
These are useful tools for evaluating carbohydrate-binding molecules, including antibodies.
The recombinant HSA produced in plants does not contain animal-derived components and cannot be contaminated with virus. Additionally, it has the same structure, characteristics, and biological activity as natural HSA. Several sugar-conjugates are available, and it is also possible to manufacture the sugar-conjugates according to customer specifications. For more details on the products and contracts, please contact us.
