This year we celebrate seventy years since the establishment of the Institute of Biophysics of the Czechoslovak Academy of Sciences (IBP) (founded on January 1, 1955). If we look into the biography of Professor Emil Paleček (born on October 3, 1930), one of the most world-recognized personalities associated with the Institute and one of the most cited Czech scientists, known as the founder of nucleic acids electrochemistry, we are drawn to the same year, i.e. 1955, as the year in which Emil Paleček finished his studies in biochemistry and joined the IBP, where he worked with admirable vitality, enthusiasm and dedication until his death (October 30, 2018). In the context of celebration of founding of the Institute, we would like to commemorate in this article a personality who significantly influenced the history of the Institute alongside the important discoveries and research directions that defined his extremely successful career. We prefer this form, which is a sort of a mini-review of the most important results of the laboratory obtained under EP's leadership over 63 years, presented in mutual context and natural relations. For his life's work, Professor Paleček received many prestigious awards, with the Czech Head Award in 2014 and the Neuron Foundation Award in 2017 being the most distinguished.

Thymidine triphosphate bearing benzylidene-tetrahydroxanthylium near-IR fluorophore linked to the 5-methyl group via triazole was synthesized through the CuAAC reaction and was used for polymerase synthesis of labelled DNA probes. The fluorophore lights up upon incorporation to DNA (up to 348-times) presumably due to interactions in major groove and the fluorescence further increases in the single-stranded oligonucleotide. The labelled dsDNA senses binding of small molecules and proteins by a strong decrease of fluorescence. The nucleotide was used as a light-up building block in real-time PCR for detection of SARS-CoV-2 virus.
