Q: What are the differences among your PEG NHS ester & PEG Acid products?
A: We offer a variety of PEG Acid and PEG NHS ester. These NHS esters react with primary and secondary amine to form a stable amide linkage. This reaction may be carried out in an organic solution with an organic base or may be carried out in an aqueous solution at or around neutral pH or slightly acidic or basic. To PEGylate proteins or nanoparticles, it often requires a large excess of PEG NHS esters due to the competitive hydrolysis reaction in an aqueous solution. Stability of NHS esters is compared by their hydrolysis half-life (T1/2). To mitigate the competitive hydrolysis reaction, organic solvents such as amine-free, anhydrous DMF and DMSO may be used in combination with an aqueous buffer solution.
