BG-NH2 is an amine-terminated building block for the one-step synthesis of SNAP-tag® substrates from NHS esters or other activated carboxyl esters of labels or surfaces.
There are two steps to using this system: subcloning and expression of the protein of interest as a SNAP-tag fusion, and labeling of the fusion with the SNAP-tag substrate of choice. Expression of SNAP-tag fusion proteins is described in the documentation supplied with SNAP-tag plasmids. The labeling of fusion proteins with the SNAP-tag substrate is described in this document.
