Metabolomics:

The institute of Molecular Biology and Biotechnologies is offering to diverse clients to perform original and targeted LC-Mass based metabolomics analyses for different compounds in plants, animals and humans. The methods for plants are developed for the resurrection plant Haberlea rhodopensis Friv., where we have long lasting experience, and very successfully can be used for other plants with high burden of phenolic substances as well as for different agriculture plants. The IMBB also offers LC-Mass targeted investigations for biologically-active compounds in medical plants and high-value bioactive commodities (carotenoids, anthocyanes, flavonoids etc.) from agriculture plants.
  1. Workflow strategy for untargeted LC-hrMS/MS metabolomics in plants. One only platform will be used for complete metabolomics eliminating the need of GC-MS and Ion chromatography.
  2. Targeted study of nicotine and nicotine glucuronide as such or being part of different bigger forms or product of decomposition
  3. Targeted analysis of amino acids (>30) and small peptides in plant tissue. An economical, practical, fast and robust method for analysis of more than 28 amino acids and up to 100 amino acid derivatives.
  4. Targeted analysis of Nucleosides, Nucleotides and Nucleobases (32 individual representatives). A simple fast and robust method for nucleobases, Nucleotides, nucleosides and their phosphate forms was developed. All analysts are analyzed in one only run with new HILIC technology.
  5. Targeted analysis for sugars in plant tissue (from 1 to 10 sugar units). One only method will be used, covering from mono saccharides up to 15 monomer oligo sugars in one run. Separation of isobars.
  6. Targeted and untargeted analysis of saponines in plant tissue, pharmaceutical forms and crude extracts. Ultrafast, ultra-informative, ultrasensitive ultra-robust method exploiting amidHILIC technology.
  7. Analysis of steroidal hormones in blood serum and plant tissue.
  8. Analysis of vitamins in blood serum and plant tissue (one analysis for water and fat soluble vitamins).
  9. Combined single analysis workflow for untargeted and targeted metabolomics and proteomics, incorporating innovative fractionation technology and Information dependent & Information independent instrumental setup for complete sample elucidation.

Bioinformatics:

The institute of Molecular Biology and Biotechnologies is offering to diverse clients to perform original and targeted bioinformatics analyses with following custom-developed software:

miRDEG:

miRDEG is a software package designed for the identification and discovery of putative novel miRNAs through the use miRNA biogenesis characteristics in sRNA sequencing data, combined with miRNA degradation product databases. The package is comprised of three separate software applications (cluster SD, miRNA2D, miCompare) and one standalone software module (LoopRNA). clusterSD focuses on the identification of sRNA clusters consistent with miRNA biogenesis and matching this against clusters of the expected degradation products of a mutative miRNA. miRNA2D focuses on analysing the secondary structures of the RNA regions identified by clusterSD, looking for characteristic primary miRNA structures. miCompare focuses on verifying putative miRNAs against databases of known miRNAs in order to verify result viability.

LoopRNA:

LoopRNA is a Java module intended to aid in the design of software for RNA secondary structure analysis. By employing OOP and Graph theory, this module represents RNA secondary structure as a non-linear tree graph comprised of standalone, internally-linked objects. This representation is considerably easier to examine via automated software while still retaining a human-readable output option. LoopRNA is not a standalone programme, but rather a module intended for implementation in larger software applications. LoopRNA is not intended to visual, store or reinterpret RNA secondary structure data. Superior formats such as Vienna and RNAML already serve this purpose well. Rather, LoopRNA is intended to create a self-contained logical architecture where each element is “aware” of its own characteristics. This architecture can be polled for simple questions which would be trivial to answer by a human operator looking at a graphical visualisation, but which are tedious and complicated to code into software and which tend to be difficult to maintain as requirements change. In short, LoopRNA is intended to examine RNA secondary structure through software as a human operator can by eye.

Clustering Module:

Clustering Module is a precursor to the clusterSD software application in the miRDEG software package. It focuses on the identification of pairs of sRNA clusters in sequencing data, which are then matched against standard miRNA biogenesis characteristics. Specifically, the Clustering Module looks for sRNA which match the sequenced miRNA and miRNA* sequences, along with their isforms, based on sequence overlap and a number of gap calculations.

IMBB offers also to perform:

  • Metagenomics investigations (bioinformatics part).
  • NGS sequencing investigations (bioinformatics part) of various genomes.
