A. Bisulfite conversion of DNA using Zymo EZ DNA Methylation-Gold Kit

Reaction Mix (1x, 150ul):

Reagent Final Conc. Vol (1x)
ddH20 10ul
Jurkat gDNA (203.9ng/ul) 2.039ug per tube 10ul
Conversion Reagent (prepared 11/6) 130ul

Reaction Program:

 98C -> 10 min
 64C -> 2.5 hours
 4C -> overnight

Column Purification:

1. Place a Zymo-Spin IC Column into a provided Collection tube.
2. Add 600 ul of M-Binding Buffer to spin column
3. Load the reaction mix into the spin column.
4. Close cap and mix by inverting 10 times. Centrifuge at 15K rpm for 30 s. Discard flow through.
5. Add 100ul of M-Wash Buffer. Centrifuge at 15K rpm for 30 s. Discard flow through.
6. Add 200ul M-Desulphonation Buffer and wait for 20 min. Centrifuge at 15K rpm for 30 s. Discard flow through.
7. Add 200ul M-Wash Buffer. Centrifuge at 15K rpm for 30 s. Discard flow through.
8. Add another 200ul M-Wash Buffer. Centrifuge at 15K rpm for 30 s. Discard flow through.
9. Place the column into 1.5ml microcentrifuge tube. Add 12ul M-Elution Buffer into center of column matrix. Wait 1 min. Centrifuge at 15K rpm for 30 s. 
10. Measure the DNA with Nanodrop.

B. PCR Amplification of Converted DNA
