Excess Tween 20 in library for HiSeq

[pmonnahan]

I recently prepared a library using the Multiplexed Shotgun Sequencing protocol (citation below) and sent the library off for sequencing on Illumina HiSeq. The library that I submitted was supposed to be at 10 nM in Qiagen EB buffer supplemented with 0.1% Tween 20. I received word that the library had failed to cluster on the flowcell.

After reviewing my notes, I noticed a large mistake...I added about ~100x too much Tween 20. The final solution was 10% instead of 0.1%. I have a feeling that this is probably what prevented clustering on the flowcell, but I can't find any conclusive info. Does anyone know if excess Tween 20 would interfere with HiSeq?

Thanks

Unfortunately, I'd say that very high Tween 20 would probably interfere with DNA binding to the flow cell. I don't think anyone would have done any definitive studies on this.

On the bright side, wasting thousands of dollars/euros/lives via minor errors is part and parcel of next-gen sequencing. Happens to us all at some point or another.
