BG-NH2 – SNAP-tag
BG-NH2 is a carboxy-reactive building block for preparing of SNAP substrates from the NHS esters or other amine-reactive forms of labels or biological targets. This BG-NH2 building block facilities the development of various SNAP-tag substrates for labeling SNAP-tag fusion proteins for a wide range of biological applications. The SNAP protein labeling system enables the specific, covalent attachment of virtually any molecule to a protein of interest. The SNAP-tag is a protein based on human O6-alkylguanine-DNA-alkyltransferase (hAGT). SNAP-tag substrates are fluorophores, biotin or beads conjugated to guanine or chloropyrimidine leaving groups via a benzyl linker. In the labeling reaction, the substituted benzyl group of the substrate is covalently attached to the SNAP-tag.
In the category of laboratory chemicals, we have collected a wide range of products starting from alcohols (mostly custom synthesized), auxiliary materials for labs, brand-name products and other interesting, chemical ...
