FIELD: medicine. ^ SUBSTANCE: invention refers to genetic engineering and biotechnology and can be used for labelling of proteins, cells and organisms. Substitutes added to nucleic acid Aequorea coerulescens, coding colourless GFP-like protein acGFP is considered as means of production of nucleic acid coding fluorescent protein. Expression cassette containing this nucleic acid under regulatory elements control provides in-cell biosynthesis of fluorescent protein. This genetic structure is used for production of transgenic organism and cell producing fluorescent protein, coded by specified nucleic acid. This fluorescent protein is applied in methods for labelling of cells, intracellular structure and protein, as well as for promotor transcriptional activity registration. ^ EFFECT: invention application ensures widen range of labelling means used in biochemistry, molecular biology and medical diagnostics. ^ 11 cl, 34 dwg, 2 ex |
