Y-Shaped PEGs

CD Bioparticels offers high-quality activated Y-PEG derivatives with high purity and low polydispersity for amine PEGylation, thiol PEGylation, N-terminal PEGylation, C-terminal PEGylation and other apps. Our Y-shaped PEG derivatives have undergone rigorous chemical purification during the synthesis process and are essentially free of activated bifunctional PEG by-products.

Our unique Y-shaped branched PEG NHS derivatives have a bulky steric structure consisting of two linear methoxy PEG chains attached to a central core with reactive NHS groups, helping to reduce the number of attachment sites for protein molecules . Our Y-shaped PEG NHS esters are readily soluble in aqueous buffers for simple and efficient modification of proteins and other lysine-containing biologics.
