Quasar 670羧酸用于标记多肽、寡核苷酸或官能化胺。Quasar 570是一种发射光谱在可见光谱红色区域中的吲哚羰花青素; 它在644nm激发并在670nm发射。该化合物是Cy5的直接替代物。BHQ-2能有效淬灭Quasar 670。
Quasar® 670 carboxy acid is used to label peptides, oligonucleotides or functionalized amines. Quasar 670 is an indocarbocyanine which fluoresces in the red region of the visible spectrum; it excites at 644 nm and emits at 670 nm. This compound is a direct replacement for Cy™5. BHQ®-2 will quench the Quasar 670 moiety.
