一、试剂基团反应特点:
西安凯新生物科技有限公司BHQ-2的吸光度为579 nm,有效吸光度范围为550-650 nm。它是与在可见光范围(557-617 nm)的黄橙色部分发射的荧光染料配对的猝灭剂。这组染料的发射光谱与BHQ-2的吸收光谱充分重叠,使后者能够高效地熄灭前者的荧光。
The absorbance of BHQ-2 is 579 nm, and the effective absorbance range is 550-650 nm. It is a quenching agent paired with the fluorescent dye emitted from the yellow orange part in the visible light range (557-617 nm). The emission spectrum of this group of dyes fully overlaps with the absorption spectrum of BHQ-2, so that the latter can efficiently extinguish the fluorescence of the former.
二、基础产品数据:

四、在FRET探针中使用暗猝灭器的优点是:
1.低背景荧光(因此具有更好的信噪比)
2.更高的动态范围
3.适用于多重分析(由于暗猝灭器没有二次荧光)
4.使用暗猝灭剂易于合成FRET探针(因为暗猝灭剂在寡聚脱保护步骤期间能够抵抗降解)。
