SiR700-BG
Benzylguanine (BG) is the substrate of the self-labeling tag SNAP-tag?*. Upon reaction with a BG derivative, SNAPtag?* forms a covalent bond with the substrate and releases guanine. It allows to permanently attach a fluorescent label
to any protein of interest (POI) expressed as SNAP-tag fusion. SiR700-BG is the benzylguanine derivative of SiR700 fluorophore. It emits light in the far-red, it is fluorogenic and well suited for STED and SIM superresolution imaging.
SiR700-BG can be imaged with Cy5 filtersets but using a 700nm LP emission filter is best. It can be used for widefield, confocal, SIM or STED imaging in living or fixed cells and tissue. Contains 1 vial of SiR700-BG (35 nmol, lyophilized).
