Quasar 570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黄橙色区域中的吲哚羰花青素; 它在548nm激发并在570nm发射。该化合物是Cy3的直接替代物。 BHQ-2能有效淬灭Quasar 570。
Quasar® 570 carboxy acid is used to label peptides, oligonucleotides or functionalized amines. Quasar 570 is an indocarbocyanine which fluoresces in the yellow-orange region of the visible spectrum; it excites at 548 nm and emits at 570 nm. This compound is a direct replacement for Cy™3. BHQ®-2 will quench the Quasar 570 moiety.
