We have developed a biochip for the analysis of candidate genes for schizophrenia. Using this biochip, allele and genotype frequencies for the polymorphisms of HTR2A, BDNF and SLC6A4 genes in 198 patients with schizophrenia and 192 healthy individuals have been obtained. The allele T of the HTR2A polymorphism rs6314 was identified as protective against the(More)
To expand the informational capabilities of molecular genetic research, on the biological microchips, new indotricarbocyanine dyes that fluoresce in the near infrared (IR) spectral region have been synthesized. The developed IR dyes were studied using a biochip-based test system for detection of mutations in the BRCA1/BRCA2 and CHECK2 genes associated with(More)
In order to expand the informational capabilities of molecular genetic research, new indotricarbocyanine dyes that fluoresce in the near infrared (IR) spectral region have been synthesized. The developed IR dyes were studied using a biochip-based test system for detection of mutations in the BRCA1/BRCA2 and CHECK2 genes associated with breast cancer. The(More)
Here, we describe the synthesis and purification of six deoxyuridine triphosphate derivatives that contain protein-like functional groups and alkene linkers of various lengths. Using KOD XL and Deep Vent polymerases, these derivatives have been incorporated into single-stranded DNA, achieving a high degree of DNA modification. These polymerases are able to(More)
In order to study the effect of an electrical charge of the chromophore, on the efficiency of incorporation of fluorescently-labeled nucleotides into DNA during PCR, three fluorescently-labeled dUPT, one of which with electroneutral and other two with positively and negatively charged dyes (Cy5 analogs), were synthesized. It is shown that dUPT, labeled with(More)
