Yes, the prepared library has to be diluted prior to running qPCR. Generally, it is recommended to run two dilution points, 1:10000 and 1:100000. For an established workflow where approximate library quantity is known, dilutions can be adjusted, but they need to fall within the range of the Collibri DNA Standards. Note that libraries should be diluted in the Collibri Library Dilution buffer that is included in the Collibri Library Quantification Kit. Dilution of the library stabilizes library molecules at low concentrations, producing accurate and reproducible results.
