Default GUIDE-seq oligo design

Hi everyone,

I am trying to understand how the primers were designed for the GUIDE-seq protocol:

GUIDE-seq enables genome-wide profiling of off-target cleavage by CRISPR-Cas nucleases
http://www.nature.com/nbt/journal/v3.../nbt.3117.html

The protocol states that I should use either sense or antisense primers, but it looks like to me that if I only use the sense primers I will get a very small PCR product only containing the ODN and other parts of the oligo and no information about the sequence next to the ODN.

To me it looks like that GSP1-sense does not fit with the GSP2-sense primer. The GSP1-sense primer aligns with the GSP2-anti oligo.

Can anyone explain how it works? I have attached a PDF of my alignments.

Thanks,

Anders
