It is the method of choice to quantitatively measure amounts of transgene DNA in a food or feed sample. Q-PCR is commonly used to determine whether a DNA sequence is present in a sample and the number of its copies in the sample. The method with currently the highest level of accuracy is quantitative real-time PCR.
Mechanism-based qPCR quantification methods have also been suggested, and have the advantage that they do not require a standard curve for quantification. Methods such as MAK2 [16] have been shown to have equal or better quantitative performance to standard curve methods. These mechanism-based methods use knowledge about the polymerase ...
Quantitative PCR instruments monitor the progress of PCR, and the nature of amplified products, by measuring fluorescence.. The range of different fluorescent labels that can be monitored, the precision with which they can be measured, and the ability to discriminate signals from different labels, are relevant performance characteristics.
Here, mRNA serves as a transient intermediary molecule in the information network, whilst non-coding RNAs perform additional diverse functions. A transcriptome captures a snapshot in time of the total transcripts present in a cell. Transcriptomics technologies provide a broad account of which cellular processes are active and which are dormant.
qPCR is unable to distinguish differences in gene expression or copy number variations that are smaller than twofold. On the other hand, dPCR has a higher precision and has been shown to detect differences of less than 30% in gene expression, distinguish between copy number variations that differ by only 1 copy, and identify alleles that occur ...
Kelly Ripa and Mark Consuelos are still mourning the death of their beloved dog, Chewie. As they were discussing a Super Bowl ad for Farmer's Dog food that showed the heartwarming bond between a ...
