Abstract:
A method for primer walking sequencing of a nucleic acid target on a template strand, which method comprises performing a series of sequencing reactions, each involving hybridising a primer to the target and effecting chain extension/chain termination of the primer, wherein for each sequencing reaction there is used a primer which is a single covalently linked oligonucleotide selected from a presynthesised set of walking primers wherein each walking primer consists of a chain of nucleotide residues and at least one nucleotide analogue residue whereby the annealing temperatures of the primer to the target are raised and/or the annealing properties of the primer to the target are improved without increasing their sequence complexity wherein the walking primers contain bases capable of pairing with any of the four bases on the template strand.
