[The detection of Leiden mutation using technique of enzymatic extension of allele-specific primer with double bioluminescent detection (PED-Biolum)].

The article deals with comparing technique of detection of Leiden mutation on the basis of PEXT-reaction with subsequent bioluminescent microanalysis of products with technique based on RT-PCR. The sampling for testing comprised 83 specimen of genome DNA including 35 specimens with known Leiden heterozygote mutation. The commercial kit "SNP-express-PB" (Litex) was used as a comparison test.

[Bioluminescent reporters to identify gene allelic variants].

The method of single nucleotide polymorphism identification based on primer extension reaction (PEXT) with the following bioluminescent solid-phase microassay was developed. The recombinant Ca2+-regulated photoprotein obelin and coelenterazine-dependent luciferase Renilla muelleri were used as reporters. Factor V Leiden polymorphism 1691 G-->A (R506Q) of human F5 gene genotyping was used for investigation.
