PCR with arbitrary primers

DNA amplification fingerprinting using two long primers.

DNA-based techniques have great potential for detecting genetic variability between genotypes. However, each approach generates different molecular markers, so the kind and amount of polymorphism detected and the cost and time required vary among them. In general, a good method for DNA fingerprinting to detect genetic polymorphism must generate a complex pattern of bands per experiment, the res...

Amplification fragment length polymorphism in Brucella strains by use of polymerase chain reaction with arbitrary primers.

DNA heterogeneity among members of the genus Brucella was demonstrated with the arbitrarily primed polymerase chain reaction (AP-PCR). Simple, reproducible genomic fingerprints from DNA of 25 different Brucella strains were generated with five arbitrarily chosen primers, alone and in pairs, with the PCR. Reaction conditions were optimized for each primer. Several DNA segments were amplified in ...

Phosphorothioate primers improve the amplification of DNA sequences by DNA polymerases with proofreading activity.

Two thermostable DNA polymerases with proofreading activity--Vent DNA polymerase and Pfu DNA polymerase--have attracted recent attention, mainly because of their enhanced fidelities during amplification of DNA sequences by the polymerase chain reaction. A severe disadvantage for their practical application, however, results from the observation that due to their 3' to 5' exonuclease activities ...
