LIQUID BIOPSY
Liquid biopsy analyses of circulating nucleic acids (cfDNA, cfRNA, miRNA, etc.) or proteins in various body-fluids can significantly improve clinical diagnosis, patient stratification and therapy monitoring. Although most of these applications are known from the cancer field, this approach has also been successfully provided for systemic and infectious diseases.
To this purpose, various multiplex technologies have been developed and successfully applied in minimally invasive diagnostics at our institute over the past 15 years. In addition, extensive know-how for the entire sample analysis and bioinformatic workflows could be developed. In the context of several liquid biopsy projects, we have so far analyzed several thousand cfDNAs from plasma in our laboratory using highly sensitive methylation and mutation analysis methods. In addition, we have developed expertise in the analysis of cfRNA and miRNA (extracellular vesicles from plasma, serum and saliva).
Both full laboratory and data analytics, which have been proven in various research projects, are available for contract research.
We offer as a service our support in the analysis of your samples and bioinformatic data generation.
