PEG

Azido-PEG3-(CH2)3OH is a PEG linker with three carbon chain between PEG fragemnt and OH group, The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Aminoethyl-SS-propionic acid is a cleavable compound containing a terminal amine and carboxylic acid group. The disulfide bonds can be cleaved using Dithiothreitol (DTT) reagent. The terminal amine can be reacted with carboxylic acid, activated NHS esters and other carbonyl compounds. The terminal carboxylic acid can be reacted with primary amines in the presence of activators such as EDC and HATU to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
