Enrichment of SMARTer ThruPLEX libraries with Agilent SureSelect platforms is easily performed. The chart below details the reagents necessary for this SureSelectQXT protocol. The module marked in red is not required when integrating with SMARTer ThruPLEX kits. This target enrichment protocol is compatible with all SMARTer ThruPLEX DNA-Seq, SMARTer ThruPLEX Plasma-Seq, and SMARTer ThruPLEX Tag-seq kits.

Protocol
SMARTer ThruPLEX library preparation
Prepare SMARTer ThruPLEX libraries according to the SMARTer ThruPLEX DNA-Seq, Plasma-Seq, or Tag-seq kit user manual.
Perform library purification using AMPure XP beads as described in the appropriate SMARTer ThruPLEX user manual.
CAUTION: For the final elution, DNA must be eluted by resuspending the beads in 30 µl of PCR grade water, not TE buffer.
SMARTer ThruPLEX library capture
Resuspend xGen Universal Blocking Oligos to 1 µl per reaction (or 1 nmol/µl) in nuclease-free water.
Using a narrow gauge needle, poke hole(s) in the lid of each tube containing a SMARTer ThruPLEX library to be used for capture.
Concentrate the SMARTer ThruPLEX library using a vacuum concentrator held at ≤45°C to reduce the volume in the tube to <10 µl. Do not completely dry the mixture.
Bring the volume to 10 µl with nuclease-free water.
To each resuspended library add:
1 µl xGen Universal Blocking Oligo - TS HT-i5
1 µl xGen Universal Blocking Oligo - TS HT-i7
Follow procedures in the Agilent SureSelectQXT Protocol starting at Chapter 3, Step 2 through the end of Chapter 4, Step 5 with the following modification: At Chapter 4, Step 1. Amplify the Captured Libraries, modify the Post-Capture PCR Reaction Mix to the following:
Reagent
Volume per rxn
Nuclease-free water
10.5 µl
5x Herculase Rxn Buffer
10.0 µl
Herculase II Fusion DNA Polymerase
1.0 µl
100 mM dNTP Mix
0.5 µl
10 µM Illumina P5 Primer
2.5 µl
10 µM Illumina P7 Primer
2.5 µl
Total
27.0 µl
The SMARTer ThruPLEX libraries are already indexed, so do not use the SureSelectQXT indexing primers.
NOTE: This protocol was developed using the SureSelectXT Human All Exon v5 Capture Library.
