Metagenomics is a promising approach in describing the phylogenetic and functional diversity of the complex microbial community. EXG is now offering the metagenomic DNA isolation from different samples, whole metagenome and amplicon metagenomic sequencing accompanied by bioinformatic analysis.

Explogen developed the production strain and purification protocol for our own Taq DNA polymerase (thanks to our researcher Dmytro). The enzyme is of high purity and efficient in amplifying DNA fragments from diverse templates. The EXG-Taq is offered for a very attractive price. Be first to try it in your lab.

Explogen and German company MyBiotech have signed the cooperation agreement launching joint efforts in antibiotic discovery and development. MyBiotech has broad knowledge and expertise in biotechnological development and production of natural compounds, which covers all aspects of upstream and downstream processes. Explogen will provide the complementary expertise in metabolic engineering of microorganisms, development of activity-oriented screening approaches, cloning and manipulating large DNA fragments, genome sequencing and bioinformatics.  The agreement between Explogen and MyBiotech establishes the cooperative Platform that will facilitate new drug discovery and development and thus will contribute to addressing the global antibiotic resistance crisis. The main goal of such cooperation is to provide new chemical entities with well-established and optimized production process as potential candidates for further development into pharmaceutical leads.

Explogen has purified denatured and soluble forms of recombinant RBD of S1-protein of SARS-CoV-2 virus.

Explogen started a series of open topic seminars. We are aiming to make science entertaining and thus inviting interesting speakers to talk about serious topics in a simple and understandable way.

The EXG’s bioinformatician contributed to understanding of cross-coronaviral humoral immune response phenomenon. Dr. Rostyslav Bilyy and his team with EXG contribution have demonstrated that Coronaviruses possess conservative domains in S-protein and disease caused by one type of virus will probably result in cross-reactive pan-coronaviral antibodies production. The paper describing this finding was recently published at MedRXiv.

For quite some time we were looking to isolate one of only a few known pathogenic to plant Streptomyces species – Streptomyces scabiei. Finally, by finding the scab-infected potato tubers on a local market we got 3 actinobacteria species, one of which was dominant. This strain, named Streptomyces ukrainascabiei EXG0031, is closely related, but still different from other known Streptomyces scabiei. However, unlike the related species, the S. ukrainascabiei is stimulating seeds germination and growth of radish sprouts. On the other hand, one of the minor isolates, Streptomyces sp. EXG0029 demonstrated a strong inhibition of radish germination. Now, with the genomics and metabolic analysis we are looking to find the factors causing this unusual behavior of both strains.

Explogen joins the common efforts in combating the COVID-19 pandemic. We purified SARS-CoV2 receptor binding domain of spike protein under denaturing conditions. The protein samples are compatible with the immunoassays such as ELISA and most importantly are suitable for vaccine development.

In cooperation with Ukrainian Speleological Association we have reached for the actinobacterial diversity of cave Zolushka (Emil Racoviță). First 10 samples brought us 36 new actinobacteria species, most of which are not Streptomyces. Their characterization will follow. 

Explogen LLC (EXG) is a small Ukrainian enterprise formed in mid-2019 in Lviv, which deploys biological approaches to access the chemical diversity encrypted within bacterial genomes. We are experts in molecular genetics and genomics of bacteria and yeast. We know how to build the strain you need and we are already here.
