应用简介:
mPEG
DBCO, also called methoxy PEG DBCO, is a pegylated DBCO (dibenzocyclooctyne)
derivative that can react with azide group without need any metal catalyst. The
strain-promoted 1,3-dipolar cycloaddition of cyclooctynes and azides, also
termed as the Cu-free Click reaction, is a bioorthogaonal reaction that enables
the conjugation of two molecules in aqueous solution. PEG DBCO derivatives have
excellent water solubility, possess fast kinetics and stability in aqueous
buffer. They are one of the best pegylation reagents to modify proteins,
peptides, antibodies, biopolymers and particles via copper free Click Chemistry
reaction.
Copper-free
Click reaction procedures:
Prepare
the azide-containing reagents in reaction buffer.
Add PEG
DBCO reagents to azide containing reagents. Add 1 mol equivalent of limiting
reagent to 1.5~3.0 mol equivalents of abundance reagent.
Incubate
the reaction at room temperature for 2~4 hours or 2~12 hours at 4 0C.
Purify
conjugates either by dialysis or size-exclusion chromatograph.
