Part# 15036187 Revision A January 2013 Performed using the TruSeq DNA PCR-Free Sample Preparation Kit (A cat#FC-121-3001, B cat#FC-121-3002)

Fragment DNA Fragmentation will be conducted using the Covaris S2 Ultrasonicator. NOTE: Thaw frozen Resuspension Buffer (10mM Tris pH 8.5) to RT˚ for use during protocol. After use place Resuspension Buffer at 4˚C for long term storage. NOTE: Turn on the Covaris system >30 minutes before starting protocol. De-gas and pre-chill the deionized H2O to a temperature of 3˚C to 6˚C. The fragmentation procedure may be started when 6˚C is reached.

Library Insert Size Options Insert Size 350bp 550bp Input DNA per sample 1ug 2ug Recommended Read Length ≤ 2x101bp ≤ 2x151bp* * Read lengths greater than 2x151bp will produce a significantly higher percentage of overlapping reads.

Validate Library NOTE: qPCR must be used to quantify TruSeq DNA PCR-Free Sample Prep libraries. Methods other than qPCR will quantify molecules that do not have adaptors on both ends and will not form clusters. More of these non-clusterable molecules may be present due to the absence of PCR enrichment and quantification by methods other than qPCR may be inaccurate. 1. Perform QC of the amplified library by loading 1ul of library on a DNA1000 or 1 ul of a 1/5 diluted library on the Agilent High Sensitivity DNA chip NOTE: Agilent run is for qualitative purposes only. NOTE: PCR-Free library fragment sizes measured on the Bioanalyzer are substantially larger than would be predicted or derived from sequencing data. This is due to anomalous migration of fragments on the chip due to the presence of certain structural features which would normally be removed if a subsequent PCR-enrichment were performed. 2. Calculate the nM concentration of each library. 3. Transfer 5 ul of each library from the TSP1 plate to a new Midi plate labeled with a DCT barcode and dilute to 2 nM concentration using EB buffer (10mM Tris HCL pH 8.5) supplemented with 0.1% Tween20.

7 4. Pipet up and down with multichannel pipette 10x to mix 5. For non-multiplexed samples that do not require pooling proceed to cluster generation NOTE: Store DCT barcoded MIDI plate with diluted libraries at -20˚C until ready to generate clusters. NOTE: Libraries diluted to 2 nM in EB buffer supplemented 0.1% Tween20 are safe for long term storage at -20˚C

Pooling Libraries (Optional) 1. Apply a PDP barcode label to a new 0.3ml plate (for multiplexing only). 2. Determine the samples to be combined together for each pool. NOTE: Verify that libraries to be pooled have unique indexes!! 3. Transfer 5 ul of each normalized library to be pooled from the DCT plate to one well of the new PDP labeled plate. The total volume of the combines sample libraries will 5x the number of combined samples (6 libraries = 30ul). 4. Pipette the entire volume up and down 10x to thoroughly mix the pooled libraries. 5. Proceed to cluster generation.
