Quantitative analysis and specific recognition of DNA molecules are of great significance to the development of genomics, virology, molecular biology and other related disciplines. However, due to weak fluorescence of biomolecules themselves, most DNA sequences are fluorescently labeled at present, and labeled DNA probes have been widely applied to automatic DNA sequencing, antibody immunoassay, disease diagnosis, anticancer drug analysis, and so forth. 

Suzhou Olipharma provides a variety of common fluorescent modification groups, which are generally used as DNA probes and can be modified at the 5' end or 3' end:
