Biocomplex is specialized in macromolecular sample preparation and purification for functional and structural studies using ultracentrifugation and chromatographic methods. Biocomplex also actively develops new purification methods, often in co-operation with manufacturers. Our technologies can be used in different combinations to purify large macromolecular complexes such as viruses, virus-like particles, viral subassemblies, exosomes, membrane vesicles, large protein complexes, ribonucleoprotein complexes etc. Biocomplex is supported by the University of Helsinki (HiLIFE and Faculty of Biological and Environmental Sciences) and Academy of Finland.
