Controls and Standard Curves in PCR

Significance of Controls and Standard Curves in PCR
from Ian Kavanagh, Gerwyn Jones and Saima Naveed Nayab writing in PCR Troubleshooting and Optimization: The Essential Guide:

Whilst qPCR is a powerful technique, the results achieved using this method is valid only if the appropriate controls have been included in the experiment. Careful selection of controls and proper Optimisation of qPCR conditions promise generation of highly specific, repeatable, reproducible and sensitive data. There are strategies for preparing both negative and positive controls for PCR, when they should be employed and how to interpret the information they provide. Standard curves are vital for determining the initial starting amount of the target template and for assessing assay efficiency, precision, sensitivity, and dynamic range. It is important to know how to prepare standards, interpret standard curve and troubleshoot inefficient qPCR reactions.
