Method for amplification and sequencing of nucleic acid polymers

摘要

Amplification and sequencing of a selected region of a target nucleic acid polymer are be performed in a single vessel. The sample is added to an amplification mixture containing a thermally stable polymerase and nucleoside feedstocks. Chain terminating dideoxynucleosides are added either at the beginning of the amplification reaction or during the course of the amplification. A thermally stable polymerase which incorporates dideoxynucleotides into an extending oligonucleotide at a rate which is no less than about 0.4 times the rate of incorporation of deoxynucleosides can be used in the amplification mixture or added with the chain terminating nucleoside.
