    摘要: Nucleic acids can be amplified and detected using a very rapid polymerase chain reaction procedure in which two different nucleic acid sequences are present. This method allows one to preferentially modulate (for example, suppress) the degree of amplification of one or more nucleic acid sequences relative to other nucleic acid sequences. This modulation is achieved by exploiting differences in the relative primer melt temperatures, or by using certain ratios of primers. Each PCR cycle is very fast, that is less than about 90 seconds. This method is particularly useful for amplification and detection of DNA associated with infectious agents that may be present in a specimen in very small quantities compared to other nontargeted nucleic acids.

    摘要: An aqueous composition containing primers for opposing strands of human cytomegaloviral DNA and a second target DNA can be used in polymerase chain reaction to provide simultaneously rapid and efficient amplification and detection of those nucleic acids. The primers for each target DNA differ in length by no more than 5 nucleotides and have a Tm within the range of from about 65 to about 74° C., while the Tm's are within about 5° C. of each other. Such compositions are useful in diagnostic test kits and methods for amplification and detection of hCMV DNA and other target DNA's using multiple capture probes, in “multiplexing”. All of the capture probes have Tm's which are greater than 50° C. and are within 15° C. of each other.
