Pcr doubling

WebPCR is an extremely flexible technique and can be adapted to: • detect mutations (base pair substitutions, insertions and deletions) in genes, • demonstrate novel fusion transcripts (gene fusions), • demonstrate clonality, • demonstrate loss of heterozygosity (loss of one allele), • detect DNA or RNA associated with infectious organisms, • WebFluorescence typically doubles with each additional cycle in the exponential phase of an efficient qPCR reaction; a lower slope would indicate that fluorescence is not doubling and suggest that PCR inhibitors may be present in your reaction (Fig 2, curve d). Compare this to an amplification curve of a reaction with a low copy number.
