一、试剂基团反应特点：瑞禧生物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：货号：Y-R-3185CAS：1214891-99-2中文名：BHQ-2 羧基英文名：BHQ2-COOH，BHQ-2 acid，BHQ-2 Carboxylic Acid（Structural）：
三、详细产品数据：Molecular formula：C25H26N6O6Molecular weight：506.52Purity standard：95%+Appearance color：Dark purple powderStorage conditions：At 20 ℃, in a cool, dry and well ventilated warehousePackaging specification：5mg、10mg、25mg等（Customized packaging will be carried out according to the situation）Solubility：（Soluble in most organic solvents, such as DCM, DMF, DMSO, THF, etc., with good solubility in water）Precautions：Keep a dry environment when using, and avoid frequent thawing for freezing.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）。五、BHQ试剂系列产品：BHQ-3 NHS ，BHQ-3 活性酯 BHQ-2 NHS ，BHQ-2 活性酯 BHQ-1 NHS ，BHQ-1 活性酯 BHQ-2 amine，BHQ-2 氨基BHQ-3 amine ，BHQ-3 氨基 BHQ-1 amine，BHQ-1 氨基 BHQ-1 acid  ，BHQ-1 羧基BHQ-3 acid  ，BHQ-3 羧基BHQ-2 acid  ，BHQ-2 羧基BHQ-1 azide，BHQ-2 叠氮温馨提示：所有的试剂仅用于科研实验。
