Cyanine compounds having the general formula I for staining biological samples, wherein R1, R2, X, Y, A1 and A2 are as defined in the specification. These kinds of compounds may show good light illumination stability, have a maximum absorption peak around 640 nm that may not change as a function of ambient temperature, have rapidly increased fluorescence intensity upon binding to nucleic acids to form compound/nucleic acid complexes, and have a light spectrum in the near-infrared region, thereby effectively reducing interference from background fluorescence and increasing the accuracy of the detection when used as a staining agent for nucleic acids in a flow cytometer. The compounds provided can be used as a staining agent for erythroblasts in the blood.
靛蓝化合物具有一般公式I,用于染色生物样本,其中R1、R2、X、Y、A1和A2如规范中所定义。这种化合物可能表现出良好的光照稳定性,具有大约在640纳米附近的最大吸收峰,可能不随环境温度变化,结合到核酸形成化合物/核酸复合物时,具有快速增加的荧光强度,并且在近红外区域具有光谱,从而有效降低背景荧光的干扰,并在流式细胞仪中用作核酸染色剂时增加检测的准确性。所提供的化合物可用作血液中红细胞的染色剂。
