AIST Develops a Precise Sugar-Chain Profiling Scanner Using a Lectin Arraying Technique, Tool for High-speed Early Diagnosis of Cancer.
AIST arrayed 40 kinds of lectins (glycol-proteins), whose specificity has already been clarified, on slide glasses. Weak interactions between sugar chains and lectins were clearly detected in real time.
AIST belives the technique can be applied widely not only to refined products, such as sugar chains, glyco-peptides and antibodies, but also to clinical specimens, such as blood, and thereby the application of glyco-protein engineering to medical technologies can be further accelerated.
The development was carried out in collaboration with Moritex Co. Ltd. (CEO, Shigeyuki Morita) to fabricate a high-performance lectin array system by combining a specified scanner of Moritex (SCAN III, the former Nippon Laser & Electronics Lab Co., Ltd., incorporated with the Moritex in 2004) with a lectin fixation technique developed by AIST.
AIST hope that the technique will play an important role in sugar chain-related fields of medicine, such as early diagnosis of cancer or rapid sorting of stem cells for regeneration medicine.
This work was published in the latest issue (November) of Nature Methods, and presented at the Biotechnology Symposium held at the Toranomon Pastral on November 22.
