Monosized superparamagnetic particles, Dynabeads®, have been used in various types of sample preparation including the isolation of cells, organelles, mRNA, genomic DNA and proteins. The magnetic beads can be used directly in crude samples such as whole blood and in 15–30 minute-protocols, the samples are purified by easy magnetic handling. The beads have also reached widespread use for analytical purposes such as solid-phase eDNA synthesis and RT-PCR, subtractive hybridization for the identification of cell-specific expression, cDNA selection for gene hunting, solid-phase sequencing, solid-phase footprinting for the characterization of DNA-binding proteins, and the specific capture of nucleic acid sequences such as viral genomes. In addition, the Dynabeads have proven to be well suited for automation which will be of importance for establishing molecular techniques in high throughput routine use such as medical diagnostics.
