LABELLING COMPOSITION AND METHOD

摘要

A labelling composition comprises a random mixture of oligonucleotides which are 6-mers to 8-mers, said composition present in a dry state. A method of making labelled probes for a nucleic acid template comprises incubating the template under chain extension conditions with the labelling composition. The use of 6-mers to 8-mers reduces self-annealing, which is a problem with 9-mers in a dried state.
