About this manual

The Illumina DNAPrep Reference Guide details a protocol for preparing up to 384 dual-indexed paired-end libraries from DNA using the Illumina DNAPrep workflow. The protocol utilizes tagmentation and enzymatic reactions to fragment DNA and add adapter sequences in approximately 15 minutes. It is compatible with DNA inputs ranging from 1 to 500 ng or higher, including whole blood and saliva samples when using specific lysis protocols.

Frequently asked questions

What is the minimum DNA input required for the DNAPrep protocol?

The protocol requires as little as 1 ng of DNA input.

Can the DNAPrep protocol be used with whole blood or saliva samples?

Yes, it can prepare libraries directly from whole blood or saliva samples when using an extraction protocol.

What is the recommended DNA purity ratio for the 260/280 absorbance?

The protocol is optimized for DNA with a 260/280 absorbance ratio of 1.8–2.0.

How long does the tagmentation step take?

The tagmentation and enzymatic reaction to fragment DNA and add adapter sequences takes only 15 minutes.
