WebApr 12, 2024 · Author summary The virus chikungunya (CHIKV) that causes long term arthritis symptoms in humans is transmitted to through the bite of the Aedes aegypti mosquito. CHIKV, for which there is no vaccine, is becoming increasingly common across the globe. We therefore need to understand the mosquito’s own ability to control CHIKV, … WebA Quantitation Assay is a real-time PCR (qPCR) assay. It measures (quantitates) the amount of a nucleic acid target during each amplification cycle of the PCR. The target may be DNA, cDNA, or RNA. There are three types of Quantitation Assays discussed in this chemistry guide: DNA/cDNA quantitation

There are many variables that impact Ct values (see above). … WebJun 28, 2024 · A The major cause for variation in PCR replicates, at copy numbers above 100, is improper background subtraction. When too little background is subtracted, the Ct will be shifted to the left. When the accuracy of background subtraction varies, the accuracy of Cq may vary accordingly.
