結構式：

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).

產(chǎn)品簡介：

  硅基羅丹明SIR（silicon rhodamine）染料是一種深紅色近紅外熒光染料、細胞滲透性強、高特異性的DNA探針。具有***光物理性質(zhì),在保留了羅丹明熒光染料*的光學性質(zhì)的同時,光譜發(fā)生明顯紅移,滿足了近紅外熒光檢測的要求,具有良好的生物相容性，其激發(fā)波通常長大于600 nm,發(fā)射波長位于近紅外區(qū)約680 nm,相對于傳統(tǒng)的近紅外菁染料,硅基羅丹明具有較好的光穩(wěn)定性,在生物成像時能夠獲得穩(wěn)定持久的熒光信號,能夠應用于長時間熒光成像進程，
