[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. It is demonstrated that proposed approach is a simple in its application, effective and relatively inexpensive technique of detection of Leiden one-nucleotide polymorphism in gene V of blood coagulation factor. The technique "PED-Biolum" has no differences in comparison with commercial technique RT-PCR concerning ability to detect mutant allele and matches it in parameters of economic effectiveness.
