BG-PEG-NH2 (SNAP-PEG-NH2) is an amino-terminal fluorescent probe building block and a precursor for site-specific labeling of SNAP-tag fusion proteins. BG-PEG-NH2 undergoes one-step coupling with activated carboxyl esters to form customized SNAP-tag substrates, which covalently bind to SNAP tags via a thioether bond formed at the Cys145 site. After coupling with a caged carboxyfluorescein, BG-PEG-NH2 forms a probe with Ex/Em = 500/524 nm following ultraviolet uncaging. Coupling of BG-PEG-NH2 with SeTau-647-NHS enables visualization of GPCR signal transduction. BG-PEG-NH2 is suitable for coupling reactions in aqueous phases or buffers, conjugation of labels, and labeling of intracellular or cell-surface proteins .
