Prepare genomic DNA for hybridization
- samples to be prepared:
- sample 1: CVF-gDNA
- sample 2: CViB-gDNA
two sheared gDNA received from Harvard:
- sample 3: CD1 PGP1 ips P16 (30ul)

End-repair Reactions
Fragmented DNA 85 ul 30ul for sample 3,4
10X End Repair Reaction Buffer 10 ul 4ul for sample 3,4

Keep the tube at room temperature (~20°C) for 30 minutes.

Note: for blunt-end ligation, the A-Tailing reaction should be skipped. Doing TA ligation is preferable since it eliminates the
chance of getting chimeric reads.

Set up ligation reaction. Note that the ATP in the Quick Ligase buffer hydrolyzes very quickly after several rounds of freeze/thaw
cycles, so it’s a good idea to make small aliquots of a fresh tube of Quick Ligase Buffer, and use one small aliquot each time.

conclusion
- It seems like we were able to capture regions covered on chr7, and got enrichment level that is 2 to 8 fold less than the gDNA across different samples.
- For DF set2 with 45C wash, I didn't get good amount of amplification during the last PCR step, I would think this is somewhat related to the low/zero enrichment level we seen in the graph. However, this is inconsistent with our previous results. Actually, in last enrichment analysis PCR, I found a mistake. I used SYBR green along with Kapa master mix. Kapa already included SYBR green, therefore adding extra SYBR green should be problematic (high concentration causes inhibition), thus the results from last time wasn't too trustworthy.
- On chr11, I saw slight rise in the curve toward very late stage of PCR on the gDNA samples. It would be good to repeat another QPCR with 50 cycles or so to see whether we will get anything useful. I am planning to do another QPCR analysis to test chr10, four NSC primers, and repeat chr7 on different 6 samples(since PCR is limited to 96 wells).

conclusion
- From the above results, we can conclude that commercialized Nimblegen kits definitely had the best enrichment level out of all. However, our padlock probe captured libraries also had satisfactory level of enrichment across several different regions of chromosomes. Also, it seems like we can skip the wash step as suggested by the results from past few experiments.
