t-Butoxycarbonyl-PEG3-NHS ester contains a t-butyl ester group and an NHS ester moiety. The PEG spacer increases the aqueous solubility of the resulting compound. The NHS ester readily reacts with primary and secondary amine bearing molecules (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. The t-butyl group is removed under acidic conditions to form a free acid, which can under further conjugations.
T-Butoxycarbonyl-PEG3-NHS ester is an organic compound used in bioconjugation and chemical crosslinking. It is a polyethylene glycol (PEG) derivative with a t-butoxycarbonyl (t-Boc) group and an N-hydroxysuccinimide (NHS) ester group. The t-Boc group is used to protect the PEG molecule from chemical reactions and the NHS ester group allows the molecule to react with primary amines. The resulting product is a stable, water-soluble linker that can be used to attach molecules to surfaces and to other molecules.
