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.
