DBCO PEG Folic acid，MW 2000 Da

DBCO PEG Folic acid, also called DBCO PEG folate, is one of Nanocs' folic acid PEG derivatives that can go Click Chemistry reaction without a need of any metal catalysts. The strain-promoted 1,3-dipolar cycloaddition of cyclooctynes and azides, also termed as the Cu-free click reaction, is a bioorthogonal reaction that enables the conjμgation of two molecules in aqueous solution. DBCO PEG folate derivatives possess fast kinetics and stability in aqueous buffer. DBCO reagents can be used to label azide-modified biomolecules spontaneous without the need for toxic Cu catalysts. Folic acid, is also known as vitamin M, vitamin B9 or pteroyl-L-glutamic acid. Folic acid is an essential bioactive molecule for numerous biological functions. It participates in the synthesis, repairing and methylation of DNA as well as to act as a cofactor in many biological reactions. DBCO functional folic acid can be easily attached to azide functionalized molecules, particles or solid surfaces.
