From blue to red: scientists experiment with the "living light" of jellyfish
Scientists of Siberian Federal University in collaboration with colleagues from the Institute of Biophysics of the Federal Research Center, Krasnoyarsk Scientific Center, SB RAS and researchers from ShanghaiTech University (China) studied the photoprotein obelin, which can be used to create bioluminescent test systems. Since photoproteins, in particular, obelin, can emit bright light when calcium ions are added, they are actively used as intracellular markers for monitoring various cellular processes. Also, obelin can be used in test systems for enzyme immunoassay, which allows you to diagnose various diseases caused by bacterial cells, viruses, fungi, protozoa and parasites. The study considers obelin activated not by a natural substrate, but by its synthetic analogue.
