Abstract
1. Нуклеиновая кислота, кодирующая флуоресцентный биосенсор для регистрации изменения рН, аминокислотная последовательность которого показана в SEQ ID No: 4.2. Кассета экспрессии, которая будучи интегрированной в геном клетки или при введении в клетку в виде внехромосомного элемента, способна обеспечить экспрессию флуоресцентного биосенсора по п. 1 под контролем регуляторных элементов, необходимых для экспрессии нуклеиновой кислоты в клетке-хозяине.3. Эукариотическая клетка, продуцирующая биосенсор, кодируемый нуклеиновой кислотой по п. 1, содержащая кассету экспрессии по п. 2 в виде внехромосомного элемента или элемента, интегрированного в геном этой клетки.4. Нуклеиновая кислота, кодирующая химерный белок, аминокислотная последовательность которого выбрана из SEQ ID NOs:6 и 8, где химерный белок включает флуоресцентный биосенсор по п. 1.5. Кассета экспрессии, которая будучи интегрированной в геном клетки или при введении в клетку в виде внехромосомного элемента, способна обеспечить экспрессию флуоресцентного биосенсора по п. 4 под контролем регуляторных элементов, необходимых для экспрессии нуклеиновой кислоты в клетке-хозяине.6. Эукариотическая клетка, продуцирующая биосенсор, кодируемый нуклеиновой кислотой по п. 4, содержащая кассету экспрессии по п. 5 в виде внехромосомного элемента или элемента, интегрированного в геном этой клетки.1. Nucleic acid encoding a fluorescent biosensor for detecting pH changes, the amino acid sequence of which is shown in SEQ ID No: 4.2. An expression cassette, which, when integrated into the cell’s genome or when introduced into the cell as an extrachromosomal element, is capable of expressing the fluorescent biosensor according to claim 1 under the control of regulatory elements necessary for expression of the nucleic acid in the host cell. 3. A eukaryotic cell producing a biosensor encoded by a nucleic acid according to claim 1, containing an expression cassette according to claim 2 in the form of an extrachromosomal element or an element integrated into the genome of this cell. A nucleic acid encoding a chimeric protein, the amino acid sequence of which is selected from SEQ ID NOs: 6 and 8, where the chimeric protein includes a fluorescent biosensor according to claim 1.5. An expression cassette, which, when integrated into the genome of a cell or when introduced into the cell as an extrachromosomal element, is capable of providing expression of the fluorescent biosensor according to claim 4 under the control of the regulatory elements necessary for expression of the nucleic acid in the host cell. 6. A eukaryotic cell producing a biosensor encoded by a nucleic acid according to claim 4, containing an expression cassette according to claim 5 in the form of an extrachromosomal element or an element integrated into the genome of this cell.
