WebDec 14, 2024 · I agree that qPCR is a complex topic which requires training, experience and optimized protocols as well as precise handling. In an attempt to answer your question: … WebFirstly, Ct stands for the cycle threshold (Ct) of your sample. This is given after the qPCR reaction by the qPCR machine. Simply, it is the cycle number where the fluorescence generated by the PCR produce is …
WebQuantitative PCR involves multiple rounds of enzymatic reactions and is, therefore, more sensitive to impurities such as proteins, phenol/chloroform, salts, EDTA, and other chemical solvents. Contaminants can also interfere with fluorescence detection. The ratio of absorbance values at 260 nM and 280 nM gives an estimate of DNA purity.
