This will ensure high processivity, specificity, fidelity, and reproducibility. 2. Common problems a. Heavy smearing in one or more lanes: i. Optimize Mg2+ concentration (usually not required). ii. Reduce the number of PCR cycles. iii. Decrease the amount of enzyme in the reaction. iv. ...
This calculation yields the concentration of the target bacterial DNA in copies per microliter. Expressing results The bacterial quantities can then be expressed as copies per gram of stool or per milliliter of the sample, depending on the normalization factor applied during sample preparation. The ...

perform quantification analysis by comparative Ct method. The Ct method compares the Ct values of the samples with standards samples. The Ct values of the controls and the samples are normalized using the Ct values obtained for housekeeping genes. To validate the Ct calculation, it is required th...

Here, we have taken into consideration the potential problems associated with using non-validated control genes for quantitative gene expression analyses and have set out to identify suitable reference genes for the normalization of qPCR gene expression data in mouse osteoblasts, osteoclasts and macrophage...
Calculation of the molar mass of the transcribed MERS-RNA was based on the sequence of the RNA and the molar mass of each nucleotide monophosphate. Thus, the efficiency of the reverse transcriptional conversion of RNAtemplateinto cDNA was determined and expressed as the ratio of RNA copy number...
and setting the fluorescence threshold for the calculation of the cycle threshold value when using a hydrolysis probe was sometimes done inconsistently between partners. In addition to this problem of result interpretation, some of the protocols required particular settings that may not have worked well...
