Input DNA
How to QC your input DNA
It is important that the input DNA meets the quantity and quality requirements. Using too little or too much DNA, or DNA of poor quality (e.g. highly fragmented or containing RNA or chemical contaminants) can affect your library preparation.
For instructions on how to perform quality control of your DNA sample, please read the Input DNA/RNA QC protocol.
Chemical contaminants
Depending on how the DNA is extracted from the raw sample, certain chemical contaminants may remain in the purified DNA, which can affect library preparation efficiency and sequencing quality. Read more about contaminants on the Contaminants page of the Community.

The RAP Top-Up Kit (EXP-RAP001) is available to provide enough reagents for another six reactions depending on how the barcodes are used.
This kit contains reagents to be used with any remaining barcodes to load another six sequencing libraries.
