Activated Y-Shape PEGs

JenKem Technology provides branched PEG derivatives for amine pegylation (Y-NHS-40K), thiol pegylation (Y-MAL-40K), N-terminal PEGylation (Y-AALD-40K and Y-PALD-40K), fluorescent PEGs (Y-FITC-40K), and more. The sterically bulky structure of JenKem Technology’s proprietary Y-shape branched PEG derivatives, consisting of two linear methoxy PEG chains attached to a central core with an active group, may help to reduce the number of attachment sites to a protein molecule.
JenKem’s Y-shaped PEG derivatives are chemically purified during synthesis and are essentially free of activated bifunctional side products. For details on the applications of JenKem Technology Y-shape PEGs please visit https://www.jenkemusa.com/proprietary-y-shape-pegs.
JenKem Technology Y-Shape PEGs with molecular weights and functional groups not listed in our online catalog may be available by custom synthesis. Please inquire at tech@jenkemusa.com about a quotation on custom PEGs. Bulk PEGs and GMP PEGs are also available upon request. Please contact us for special bulk pricing.
