Chemical Modification Reagents Archives

Quanta BioDesign’s chemical modification reagents cover a broad range of functional groups, including carboxylic acids, NHS esters, TFP esters, primary amines, and thiols. Proteins, peptides, other biomolecules, and appropriately functionalized surfaces are modifiable with these products. We offer dPEG^® products with linear and branched dPEG^® architectures. Branched dPEG^® reagents can reduce renal clearance and increase in vivo circulation times of conjugated biomolecules.
