The Universal Set of 99 InDel Markers for Human Identification.

The aim of this work was to select InDel markers sufficient for human identification and to create a routine method for their genotyping. We analyzed the allele distribution of all known InDels in European, East Asian, South Asian, African, and American populations and selected markers whose minor allele frequency, MAF, was ≥ 0.30.

[Development of Biological Microchips on an Aluminum Support with Cells Made of Brush Polymers].

A method has been developed for manufacturing biological microchips on an aluminum substrate with hydrophilic cells from brush copolymers with the formation of a matrix of cells using photolithography. The surface of aluminum substrates was previously coated with a thin, durable, moderately hydrophobic layer of cross-linked polymer to prevent contact with the aluminum surface of the components used in the analysis of nucleic acids. Aluminum biochip substrates have high thermal conductivity and low heat capacity, which is important for the development of methods for multiplex PCR analysis on a chip.

Protein Biochips with Three-Dimensional Hydrogel or Polymer Brush Elements for the Detection of Human Serum Immunoglobulin E Specific to Inhalation Allergens.

The development of rapid analysis of human serum for the presence of allergen-specific Immunoglobulin E (IgE) is currently important. Consequently, we developed two types of three-dimensional (3D) protein biochips. The first one is a 3D hydrogel biochip containing hydrogel droplets with protein molecules (allergens, immunoglobulins and others).

Optimized Method for the Synthesis of Alkyne-Modified 2'-Deoxynucleoside Triphosphates.

A general approach is presented for synthesizing alkyne-modified nucleoside triphosphates via the Sonogashira cross-coupling reaction of unprotected halogenated 2'-deoxynucleoside, followed by monophosphorylation and the reaction of the corresponding phosphoromorpholidate with tributylammonium pyrophosphate. A highly efficient approach for the milligram-scale synthesis of base-modified nucleoside triphosphates with an amino acid-like side chain was developed. The present chemical method outweighs the other reported methods of a base-modified nucleoside triphosphates synthesis in terms of it being a protection-free strategy, the shortening of reaction steps, and increased yields (about 70%).
