BG-PEG-NH2 is an amine-terminated building block for the one-step synthesis of SNAP-tag substrates from NHS esters or other activated carboxyl esters on labels or surfaces

This compound allows you to make custom SNAP-tag substrates for labeling SNAP-tag fusion proteins for a wide range of applications. BG-PEG-NH2 is particularly useful for the synthesis of SNAP-tag substrates with affinity ligands or solid surfaces.
