introduction butyrivibrio fibrisolvens strains are presently recognized as the major butyrate-producing bacteria found in the rumen and digestive track of many animals and also in the human gut. in this study we reported the development of two dna based techniques, quantitative competitive (qc) pcr and absolute based real-time pcr, for enumerating butyrivibrio fibrisolvens strains. despite the ...

The two most commonly used methods to analyze data from real-time, quantitative PCR experiments are absolute quantification and relative quantification. Absolute quantification determines the input copy number, usually by relating the PCR signal to a standard curve. Relative quantification relates the PCR signal of the target transcript in a treatment group to that of another sample such as an ...
