The invention relates to two series of synthesised indolenine pentamethine dyes (37 compounds) comprising a reactive group in the third and fifth positions of the indolenine cycle, respectively. A method for producing, extracting and purifying the dyes and the precursors thereof, consisting in determining the absorption and fluorescence maxima, molecular extinction factors, fluorescence quantum yields, relative fluorescence effectiveness at excitation on a wavelength of 635 nm (detection of 670 nm) and 655 nm (detection of 690 nm), relative light stability and comparative sensitivity of detection of marked oligonucleotides on biochips of the claimed dyes, is disclosed. The use of the claimed dyes in the form of fluorescent marks for oligonucleotide and protein chips is also disclosed.
本发明涉及两个系列的合成吲哚啉五甲胺染料(37 种化合物),它们分别在吲哚啉循环的第 3 位和第 5 位含有一个活性基团。本发明公开了一种生产、提取和纯化这些染料及其前体的方法,包括确定所称染料的吸收和荧光最大值、分子消光系数、荧光量子产率、在 635 纳米波长(检测 670 纳米波长)和 655 纳米波长(检测 690 纳米波长)激发下的相对荧光效力、相对光稳定性以及在生物芯片上检测标记寡核苷酸的比较灵敏度。还公开了所要求的染料以荧光标记的形式用于寡核苷酸和蛋白质芯片。
