Abstract

A method for amplification and detection of a low copy target nucleic acid includes coamplification of a high copy target nucleic acid. After a number of conventional amplification cycles which include a denaturation step, several cycles are carried out during which the denatured products are renatured for a brief period of time. This intermediate step in later cycles of the amplification process reduces the effective concentration of the high copy target nucleic acid available for amplification in later cycles, thereby making more DNA polymerase available for amplification of the low copy target nucleic acid.
