Axispharm provides you with high purity tert-butyl octadecanedioate-NHS ester with a tert-butyl ester group on one end and an NHS ester moiety on the other end. The tert-butyl group can be deprotected under acidic conditions. NHS esters can react specifically and efficiently with primary amines such as the side chains of lysine residues or aminosilane-coated surfaces to form covalent bonds under neutral or slightly basic conditions.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
