AqueaTether™ (AqT™) Technologies

AqT™ Products

AqueaTether™ (AqT™) crosslinking reagents and polymers are novel proprietary biomaterials with innovative chemical architectures invented at CellMosaic based on a class of natural and edible sugar alcohol compounds. AqT™ molecules are designed for labeling and conjugating biomolecules with very hydrophobic small molecules, such as fluorescent compounds, biotin, and small molecule drugs. Branched AqT™ crosslinking reagents can also be designed to allow high amounts of detecting molecules to be loaded onto a biomolecule for detection purposes. For AqT™ technologies in the application of drug development, please visit our website at www.aqttherapeutics.com

Sugar molecules are probably the most hydrophilic natural compounds to date due to their hydrogen bonding capability (donor and acceptor). Sugar alcohol, also known as polyol, is a hydrogenated form of carbohydrate in which the carbonyl group (aldehyde or ketone) has been reduced to a primary or secondary OH group. Sugar alcohols occur naturally in foods and come from plant products, such as fruits and berries. Sugar alcohols are often used as ingredients in sweeteners and for making polymers such as hydrogel. The following is a list of some popular sugar alcohols that can be used for making AqT™ crosslinkers:

3- Carbon 4- Carbon 5-Carbon 6-Carbon
Glycerol Erythritol Arabitol Mannitol
