NH-bis(PEG2-propargyl) is a multi-branched linker with two terminal propargyl groups and an amino group. The propargyl groups reacts with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry to yield a stable triazole linkage. The amino group is reactive with carboxylic acids, activated NHS esters, and carbonyls. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-PEG4-PC represents a photocleavable, PEG linker consisting of a DBCO group that can be used for copper-free Click Chemistry reactions. This structure allows for efficient photorelease of linked molecules, typically achieving over 90% cleavage in 5-25 minutes using a near-UV lamp. The PEG4 spacer increases the hydrophilicity of the compound.
