               Next-generation sequencing (NGS) has allowed a massive increase in capacity to sequence genomes at
               relatively low cost and in a short time frame. It has revolutionized multiple aspects of biological research
               and is actively being adopted into profiling human B cell receptor (BCR) repertoires. Several NGS
               platforms are currently available, with average read lengths of 75 bp to 8,500 bp and different error rates.

               Using NGS, we successfully constructed database of human BCR repertoire from convalescent patients who
               recovered from severe fever with thrombocytopenia and middle east respiratory syndrome. Afterwards,
               we developed algorithms for analyzing the diversity, enrichment pattern, accumulation of somatic
               hyper-mutation in BCR repertoire. Through in silico analysis we selected clones of interest and prepared
               recombinant antibodies using a mammalian transient expression system. Their reactivity to viral coat
               proteins and virus-neutralizing capability was confirmed in in vitro and in vivo experiments.

               Currently we are investigating the clinical value of BCR repertoire profiling in autoimmune disease patients
               including Neuromyelitis Optica and various cancers.

               12. Biobank in Pilsen, Czech Republic, efficient tool for cancer research and personalised
               treatment

               Department of Immunochemistry, University Hospital Pilsen, Pilsen 304 60, Czech Republic.

               Biobank in University Hospital (UH) Pilsen is newly established (opened in April 2017) hospital integrated
               biobank, based on previous high quality sample collection. Sinece 2000 the hospital respository started
               to collect and store systematically biological material of  patiens for research in the UH. The main
               diagnoses for sample collection are oncological samples of breast cancer, colorectal cancer, liver and kidney
               carcinoma,  and prostate cancer.


               To be a fully-fledged biobank the following activites have been realised: collection and storage high
               quilty biological material (blood, serum and plasma) of oncological patients, collection management and
               storage of related data, implementation of ethical, social and legal issues, harmonization of IT systems,
               implementation of relevant requrements for providing biological material to the Czech Republic and
               abroad, preparation of education and training programmes and courses, active participation on BBMRI -
               ERIC activities, and cross-boarder collaboration in the BRoTHER projet.

               Currently is the biobank ready to implement aspects of personalised medicine in practice. Regarding the
               high quality aspects the selected long and short term stability of tumor markers are studied. Together
