The nCounter® SPRINT Profiler (manufactured by NanoString Technologies, Inc.) allows simultaneous quantitative analysis of up to 800 nucleic acid sequences (DNA and RNA) or proteins in a sample (or simultaneous quantitative analysis of up to 200 nucleic acid sequences in 4 samples). Fluorescently labeled probes bind to specific nucleic acid sequences in the sample, while unbound probes are removed during sample preparation.

Using a microscope and computer image analysis, the system determines the type and number of bound probes and thus enables the quantitative analysis of nucleic acids and proteins. The advantage of the system is the quick and easy preparation of the sample for analysis, while no amplification, transcription into cDNA and library preparation is needed. It also allows analysis of complex samples such as FFPE (Formalin-Fixed Paraffin-Embedded) samples, tissue samples, lysates and fluids.

Location: ELIXIR-SILVR (KRVS) unit.

The SeqStudio Genetic Analyzer is the fourth generation of 4 capillary, electrophoresis (CE) so-called Sanger sequencers. SeqStudio is an automated capillary electrophoresis system for nucleic acid analysis. It automatically performs sampling, polymer exchange, DNA separation and simultaneous detection of fluorescence in 4 capillaries. The system supports both sequential and fragment analysis on a plate (96-well) or in tubes (8-set) at the same time. Additionally, it allows the addition of new samples during the analysis. The work analysis program can be prepared on a computer, on the device itself (large touch screen), downloaded via WI-FI, LAN communication.

SeqStudio supports the same reagents as other Applied Biosystems multi-capillary sequencers (family 3500 and 3730, old systems 310 and 3130). Chemistry of BigDye ™ Terminator 1.1 Kit and BigDye ™ Terminator 3.1 Kit terminator are used for sequence analysis. Several dye chemistry is supported to perform fragment analysis, up to and including the last six dye chemistry.

The main applications are: plasmid sequencing, analysis in oncology (mutation confirmation-orthogonal technology), species identification, CRISPAR-Cas9 analysis – genome editing (diagnostics, pharmacy), forensic analysis, SNP analysis (SNAP shot genotyping), multiplex ligation ( MLPA; CNV) and other analyzes in pharmacy, diagnostics, environmental protection, microbiology.

In addition to classical sequential and fragment analyzes, the system enables various analyzes useful in diagnostics from HLA, CF, HIV, analysis of bacterial and fungal communities, comparative sequencing, validation of certain regions.

The upright confocal laser scanning microscope is equipped with a motorized microscope table which enables scanning along the x and y axes and focusing along the z axis.

It contains 10x, 40x and 63x objectives, 448 nm, 488 nm, 552 nm and 638 nm wavelength lasers and two scanning detectors, one of which is a super sensitive GaAsP detector. To ensure optimal conditions for multicolor imaging, the detectors provide a freely adjustable wavelength detection bandwidth.

The software allows time-lapse imaging in xyz coordinates, uncoupling the spectra of individual fluorescent dyes and motorized scanning of multiple regions of interest. The main advantage of the microscope is the large working distance (25 cm) between the motorized microscope table and the target focal plane, which allows in-vivo observation of large samples, such as plants.

Location: ELIXIR-SILVR (KRVS) unit.

 

The RIEGL miniVUX-2UAV is an extremely light laser scanner designed specifically for integration with drones. The sensor enables a pulse repetition rate of 100 kHz to 200 kHz, ie with 200,000 measurements per second, with a 360-degree field of view. This creates a dense dot pattern on the ground and thus allows good resolution capture of small objects. Spatially accurate data is provided by three GPS / GNSS sensors in the Trimble APX-15 UAV (V2) inertial system. The latter allows direct georeferencing with data collected by sensors mounted on the drone. The DJI Matrix 600 Pro is a six-rotor drone and is equipped with hardware and software support for flying missions. Autopilot A3 Pro uses diagnostic algorithms to compare data from all three GNSS units and, together with dedicated vibration damping, ensures a stable flight.

Typical applications: Agriculture and forestry (e.g. plant canopy architecture and phenotyping), mapping of glaciers into snowfields, archaeology and cultural heritage documentation, construction site monitoring, landslide monitoring. 

 

The NextSeq2000 system enables innovative and highly efficient biological systems research and works on various next-generation sequencing (NGS) applications. Applications include small whole-genome (≤5 Mb; bacteria, viruses, and other microbes), exomes, amplicons, target enrichment, total or targeted RNA sequencing, Chip- and ATAC-Seq, methylation, ctDNA, mRNA, and single-cell RNA sequencing or targeted gene panels sequencing.

 

The system is based on the patterned flow cell technology, allowing significantly increased data processing capacity compared to other NGS systems. At the same time, faster sequencing with the same accuracy is provided by two-channel synthesis sequencing (SBS). The system takes advantage of an integrated cartridge that includes reagents, fluidics, and the waste holder, simplified library loading and flow cell insertion as well as simplified instrument use. The NextSeq2000 generates enormous amounts of DNA data; ultra high-density flow cells enable tunable outputs from 60 to 360 Gb. Fast and accurate analysis performed by DRAGEN Bio-IT platform is suitable for novice and expert NGS users alike.

The MARVIN ProLine seed analyser (MARViTECH GmbH) is a measuring system for daily laboratory use of samples of different kind of seeds (cereals, vegetables, flowers, oil-seeds etc.) of grain sizes from 0,8mm.

 

It enables:
– measuring of total number of the sample, thousand grain weight (TGW), grain dimension (length, width, area), determination of dark or bright seeds (for flat seeds);
– determination of size fractions (length, width, area), hectolitre weight (approximately), single seed data.


The measuring time is very fast (< 3 sec), counting accuracy is at least 99%, a large seed tray enables measurements of a high number of seeds. Preconfigured connecting and controlling of electronic scales, printer and barcode-reader is possible. All measuring data can be exported in *.csv, *.txt or *.xls format or to database.

Laboratory for single cell analysis

The LSM 900 confocal microscope allows the study of the three-dimensional distribution of fluorescently labeled molecules in cells and tissues. It is adapted to work with in vitro systems such as cell and tissue cultures, organoids and tissue slices.

The confocal system includes a chamber for maintaining cells at an adjustable temperature and gas concentration (CO2 and O2), which allows long-term experiments on living cells and the study of cell-physiological processes in these cells.

The Chromium Controller enables Chromium Single Cell (SC) and Linked-Reads Genomics Solutions. Chromium SC analyses include gene expression, epigenetics (ATAC), cell surface proteins analysis, immune profiling and targeted gene expression on a single-cell level.

The Chromium platform, powered by Next GEM technology, enables integrated analysis of SC at a massive scale. The key to this technology is the ability to generate tens of thousands of single-cell partitions, each containing a unique identifying barcode for downstream analysis.

GridION is a third-generation sequencer from Oxford Nanopore Technologies, which enables long DNA, RNA or cDNA fragments sequencing. Nucleic acid sequence identification is based on the change in electric current during the passage of DNA/RNA through a protein pore.

Sequencing can take place on 5 flow cells simultaneously, on which up to 150Gb can be read in total, thus enabling the sequencing of genomes and transcripts of all types of organisms, including humans. Nanopore technology enables sequencing and assembly of as yet unknown genomes. The computer capacity of GridION enables base-calling in real time and thus enables monitoring and control of the sequencing process.
