This package contains 30 nmol of SNAP-Cell TMR-Star substrate, sufficient to make 10 ml of a 3 µM SNAP-tag fusion protein labeling solution.The SNAP-tag protein labeling system enables the specific, covalent attachment of virtually any molecule to a protein of interest. The SNAP-tag is a small protein based on mammalian O6-alkylguanine-DNA alkyltransferase (AGT). SNAP-tag substrates are derivatives of benzylpurines and benzylchloropyrimidines. In the labeling reaction, the substituted benzyl group of the substrate is covalently attached to the SNAP-tag.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 the fusion proteins with the SNAP-tag substrate is described below.Figure 1:Live COS-7 expressing mitochondrial cytochrome oxidase 8A-SNAP (COX8A-SNAP) were labeled with SNAP-Cell TMR-Star (red). Nuclei were counterstained with Hoechst 33342 (blue).Figure 2:Excitation (dotted line) and emission spectra of SNAP-Cell TMR-Star after coupling to SNAP-tag in buffer at pH 7.5Figure 3:Structure of SNAP-Cell TMR-Star (MW 677.1 g/mol)
