Gel Quantification of ligated product[edit]
File:ZhangLab 2 2010-03-21 14hr 21min.jpg
- band is relative weak, but seems like it is at the right size, I doubt we can get any thing after bisulfite conversion. Will perform a pcr amplification to amplify ligated product. Also move on to bisulfite conversion with the remaining product.
- Might have overestimated the amount of DNA, although nanodrop shows that the concentration is at 33ng/ul and I used 10ul. It is better to perform a PAGE
- Two bands above 180bp shows that a half ligated product is being developed, hence should double the amount of adapter used
- Low Yield of ligated products, DNA might have lost during washing step, need to save 1/10 after each purification to perform a PAGE. Also skip the washing step between end repair and A-tail.
