FIELD: chemistry.
SUBSTANCE: group of inventions relates to the field of biochemistry. Claimed is a device for nucleic acid sampling, application of the device of nucleic acid sampling, a set for nucleic acid amplification, as well as a method of nucleic acid amplification. The device includes a probe for holding the nucleic acid sample and a manipulator, connected to the probe with an account of a possibility of the probe manoeuvring. The probe includes a multitude of probe elements, which are capable of travelling with respect to each other between approximated and mutually remote configurations. Each probe element has a nozzle. When the probe elements move into an approximated configuration, each nozzle is joined with other nozzles to form a composite nozzle. The composite nozzle is capable of contacting with nucleic acid in order to deliver its sample. The method of amplification of nucleic acid from higher eukaryotes includes the contact of the sampling device with a source of nucleic acid from higher eukaryotes, introduction of the sampling device or its part into a reaction vessel to carry out the reaction of nucleic acid amplification without preliminary material processing and realisation of the reaction of nucleic acid amplification.
EFFECT: inventions provide portability, easiness of the application of device for nucleic acid sampling, as well as carrying out the analysis in the short period of time.
