Solid phase methods



In 1988, we showed for the first time that the biotin-streptavidin system could be used for efficient solid phase sequencing (1). Magnetic beads were developed to facilitate the solid phase handling (2,3,4). A new principle for DNA diagnostics was also developed called DIANA (Detection of Immobilized Amplified Nucleic Acids) based on the streptavidin system (5,6). The sequencing approach was used for analysis of clinical samples, such as patients with HIV (7) and HCV (8) infections and for forensic analysis (9,10). Extensive evolutionary studies was also performed to study the evolution of bacteria (9) and domestic dogs (12) as well as the epidemiology of HIV infections in patients (8).
