Abstract
Described is a process for detecting the presence or absence of one or more target nucleotides. A primer is added to a solution containing DNA. The solution is put under conditions favorable to PCR amplification using sequence specific primers. Background is removed and product is then measured to determine the presence or absence of target.
Claims3
A process for detecting the presence or absence of at least one target nucleotide in a DNA sequence, comprising:
- a) adding a first primer to a solution containing a first sample of the DNA;
- b) adding a second primer, which differs from the first primer by at least one base within 3 bases from and including a 3′ terminal base, to a solution containing a second sample of the DNA;
- c) adding a polymerase to each sample;
- d) performing PCR amplification;
- e) reducing background nucleic acids using a background reducer;
- f) measuring an amount of DNA from each sample;
- and,
- g) comparing the measurements of each sample for determining if the target is present.
5 more elements
A process for detecting PCR amplification product, comprising:
- a) performing a PCR amplification reaction;
- b) adding a background reducer to the PCR amplification product;
- c) detecting an amount of DNA present;
- and,
- d) comparing the amount of DNA detected to a baseline standard to determine if amplification product is present.
