SUBSTANCE: method includes treating a sample with a denaturing buffer solution, sorbing short RNA on a fibre glass sorbent in the presence of a chaotropic agent, followed by washing off non-bonded biopolymers and chemical reagents from the sorbent and eluting the end product. The biological fluid sample undergoes two-step denaturing, wherein at the first step two volumes of the denaturing buffer solution are added to the sample and at the second step two volumes of 96% ethanol and equal volume of chloroform are added to the obtained mixture, followed by stirring and separating the residue by centrifuging. Non-bonded biopolymers are washed off from the sorbent twice with the buffer solution and elution of the end product from the sorbent is carried out with the buffer solution.

SUBSTANCE: inventions relate to the field of DNA-genealogy and deal with a method of determining haplogroups of human Y-chromosomes, a test-system and oligonucleotide primers. The characterised method is realised in two stages. At the first stage genetic typing is carried out by basic haplogroups R,N,J,I,Q,C,E,D,G,O of an Y-chromosome tree by multiplex PCR with the application of specific oligonucleotide primers of the first and second sets of the test-system. At the second stage, if mutation is detected, additional multiplex PCR for typing by subhaplogroups is carried out. If at the first stage mutation is not detected, multiplex PCR for typing by rare haplogroups A,C3,F,H,K,L,O3 and T is carried out. The area of annealing primers outside mutation zones within the limits of species specificity corresponds to sequences from the first set of the test-system. The area of annealing of the oligonucleotide primers, directly adjoining the mutation zone within the limits of species specificity corresponds to sequences from the second set of the test-system.

EFFECT: inventions can be applied for the determination of haplogroups of the human Y-chromosome.
