Digestion of PGP1F with Rnase I
PGP1F(35ng/ul) 100ul + 10U/ul Rnase I 2ul -> 37C 30mins -> 70C 20mins. IMR90(25ng/ul) 100ul + 10U/ul Rnase I 2ul -> 37C 30mins -> 70C 20min. Purify with Microcon column. Yield: IMR90 50ng/ul x 40ul. 260/280=0.96 PGPF1 57.8ng/ul x 50ul. 260/280=0.96
Bisulfite conversion of DNA using Zymo EZ DNA Methylation-Gold kit

16 | IMB90_2 | 50ng/ul x 2 tubes | 20ul | 0ul | 130ul | 68ng/ul x 10ul | 1.48/0.93 |
17 | PGPF1 | 57.8ng/ul x 3 tubes | 20ul | 0ul | 130ul | 119.5ng/ul x 30ul | 1.79/1.28 |
- 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:
