Research

Laboratory of Omics technology was created in order to provide other laboratories research in the field of next-generation sequencing (NGS), mass spectrometry of proteins and big data analysis.

From 2014 till 2016 we have been realizing a project "Establishment of a diagnostic panel to the qualitative and quantitative assessment of the intestinal microbiota composition", supported by Ministry of Education and Science Of Russuan Federation.

Equipment and methods

MALDI TOF/TOF Ultraflextreme

Determination of mass homogenous unhydrolyzed protein or peptide with an accuracy of 0.5 - 0.01% 
Top-down identification of proteins - including sample preparation and 2D gel trypsin digestion in the gel
Bottom-Up approach. Sequencing of the protein sequence denovo
Determination of post-translational modifications

MALDI Biotyper

Identification of microorganisms (including the strain-specific identification)

Analysis of the quality control and SNP genotyping oligonucleotides (based on GENOLINKTM package)
Profiling proteome - research profile of biomarkers and identifying individual biomarkers in various studies of clinical proteomics (mass spectrometer microflex used CLINPROT system to search for peptide and protein bio-markers, allowing for automated sample preparation on the magnetic particles, and use software tools for data analysis, visualization and build statistical models).
Additional features: AnchorChip technology (allows to obtain homogeneous, clearly positioned on the sample target, automate data collection, as well as to increase the sensitivity of up to two orders of magnitude)

Maxis Impact

Top-down approach. Identification of proteins with high precision - sample preparation includes 1D gels in solution and trypsinolysis

Semi-quantitative proteomics, pseudoMRM method
Method MudPit - preliminary fractionation of a mixture of peptides and subsequent identification of the tryptic peptides by mass spectrometry
