Detection of immobilized amplicons by ELISA-like techniques

The NucleoLink surface is a physically modified, thermostable, optically clear resin. It allows the covalent binding of 5'-phosphorylated oligonucleotides. Target DNA amplification by polymerase chain reaction (PCR) is accomplished by asymmetric amplification on the covalently immobilized primer that develops into immobilized amplicons. A DNA fragment of bovine leukemia virus is used as a model system for the detection of immobilized amplicons by ELISA-like techniques. Covalently bound oligonucleotides are also utilized as capture probe in the hybridization-based signal amplification for detection of an infectious organism.
