- Add 900ul ddH2O, 300ul M-Dilution Buffer and 50ul M-Dissolving Buffer to a tube of CT Conversion Reagent.
- Add 130ul of CT conversion reagent to samples.
- 98C 10min -> 64C 150min -> 4c overnight.
- Add 600ul M-Binding buffer to spin columns.
- Add the converted samples to the columns, close the gap and mix by inverting several times.
- Spin at 15,000rpm for 30sec.
- Add 100ul M-Wash Buffer, spin for 30 sec, discard flow-through.
- Add 200ul M-Desulphonation Buffer, wait for 20min, spin at 15,000 rpm for 30sec.
- Add 200ul M-Wash Buffer, spin for 30 sec.
- Place the columns into 1.5ml tubes, add 10ul M-Elution Buffer. Wait for 1min, spin at 15,000rpm for 30sec.
- Measure the DNA with Nanodrop:RNA
I got low concentration after bis-conversion. i quantified the gDNA concentration with nanodrop and redo the bis-conversion.

After A tail, I did size selection for No7 and positive control, then do the adaptor ligation.
After adaptor ligation, i goes to PCR directly without size selection again.
However, I can only see the positive control product only.
So I skipped the size selection before adaptor ligation for No 1~6, and do the size selection after adaptor ligation. However, the expected band after PCR is so weak that I am not sure the targets were successfully amplified.
