About the lab

The laboratory focuses on a wide range of genetic and epigenetic analyses. Besides the standard molecular-genetic methods, our portfolio includes also more elaborated microarray technology and massive parallel sequencing (NGS).

In addition to our scientific research activities, the laboratory also intensively participates in the implementation of personalized, predictive and preventive medicine into clinical practice.  In close cooperation with the University Hospital in Martin, we mainly focus on the determinants of oncological, cardiovascular and hematological diseases. We also offer modern and popular non-invasive fetal testing from maternal blood.

Our laboratory has been using the state-of-the-art sequencing platforms from Illumina company  (NextSeq, MiSeq and HiSeq) for more than five years. We mainly focus on the entire genome sequencing, targeted resequencing based on the PCR approach, as well as on hybrid capture of target fragments.

Equipment of the lab also allows to perform other techniques such as RNA sequencing – expression profile determination, sequencing of small non-coding RNAs and many others.

DNA / RNA analyses

Thanks to the cooperation with the Institute of Molecular Biology and Genomics JFMED CU, our laboratory is able to perform multiple DNA and RNA analyses using the methods of  ddPCR, Sanger sequencing, HRM, TagMan, RT-PCR and the others.


In the field of epigenetics, our laboratory predominantly focuses on the detection of methylation of CpG islands by quantitative pyrosequencing.  The MS MLPA technique is used to detect DNA methylation changes, DNA copy number variability (CNV), as well as a methylation-specific PCR. The laboratory has extensive experience with miRCURY LNA miRNA method to perform the analysis of miRNA expression in several diagnoses. We have also introduced a microarray technology for tissue and plasma miRNA analyses.

DNA editing

Using CRISPR/Cas9 technology, we are able to create experimental cell lines with impaired expression of selected genes or modify these genes by introducing mutations. Moreover, we are able to label selected genes with sequences coding for fluorescent proteins, which allows us to gain new insights into the function of these genes. For this purpose, we have introduced methodologies for the preparation of plasmids and lentiviral vectors using advanced gene manipulation techniques, such as Gibson assembly, overlapping PCR, or site-directed mutagenesis, as well as cell culture techniques.

Non-invasive prenatal testing

Our laboratory offers also non-invasive prenatal testing of the fetus from the maternal blood. The trisomy of chromosomes 13, 18 and 21 and the sex of the fetus can be determined by the NGS method. In addition, the RT PCR method is used to specify the Rh factor of the fetal blood and the sex of the baby.
