Hi All,

I have also been curious about whether it's possible to use TruSeq or other 3rd party lib prep methods in conjunction with SureSelect. I understand the importance of using the appropriate blocking oligos for the adapters used, but I was wondering about an even simpler issue: is it possible to order the SureSelect capture kits without ordering a matching lib prep kit? I know they have separate part numbers, but their website gives the impression that they must be ordered together.

Hi SeqTruth,

We have purchased both Agilent SureSelect and NimbleGen bait libraries without ordering a matching library prep kit. We use a "home-brew" protocol to produce libraries with 64 barcodes. For the SureSelect hybridizations, we use their bocking oligo mix that comes with the kit. For the NimbleGen bait libraries, we purchased HPLC purified blocking oligos with deoxyinosines at the barcode positions and a phosphorothioate bond at the end. We get 55-70% reads on-target (Picard) using baits from either company.

I have been told by my rep that they now sell the baits separately...without the library kit. The wrinkle here (and a continued annoyance) is that there is no way to get the hyb reagents as well...without resorting to a custom order. It is possible however to get JUST the library kits if needed.

Hi ECO,
Have you had a chance to see how the 6-I or other modifications compare? It is quite an expense to order the full blocking oligos, so if the 6-I works decently we might do that. We saw also ~45% with split oligos, which is not quite good enough for us.

I'm testing the 6xInosine and LNA-split configurations and will report back.

Hey ECO,

Our lab is looking to complete a truseqDNA library prep combine with a targeted exome capture using Agilent's hybridization kit. We have blocking oligos (from roche's blocking oligo kit) for each truseq index adapter. We are curious to the exact make-up of your hybridization reaction. I am assuming the hybridization buffer mix is the same and that you have altered the Sureselect block mix.

You stated that you do not add sureselect block #3, but do you add suresect block #1 and #2? How much of the specific truseq blocking oligos do you add?

I appreciate the help!

Hi All,

I saw there was a lot of discussion on this thread back in 2012, but, then it has no posts since then. I am doing sureselect xT capture and using their own library prep kit and blockers I am getting only 40% on-target capture. I am also looking in to some home brew versions of the adapters and blockers. If anyone who has a protocol that works with home-brewed library prep method and sureselect capture can they share that on the thread. Also, ECO I saw that you were trying 6 Inosine modification on index adapter blocker in 2012. Did that work? Can you please share the results on thread.

Thanks,
Suman

Hi, ECO. I am wondering how to determine the concentration to use of the newly designed
"Block #3". What I am now using is Agilent SureSelect XT Target Enrichment System (not pooling version), and it required in total 750ng DNA as input for hybridization and 0.6ul Block #3. As I wanted to adapt this protocol , how much adapted "Block #3" should I add? Will 50uM equal amount mixture be sufficient?
