Real time monitoring of DNA manipulations. Using sensor chip SA with streptavidin bound to the surface it is possible to immobilize 5' biotinylated oligonuleotides. With this as a basis, DNA manipulations such as oligo annealing, oligo hybridization, DNA ligation, DNA synthesis and cleavage with endonucleases can be investigated.
