Exp. 1 PAGE purification on the CpG MIP PCR amplicons did on 12/09/2007
I hope that one of the 300- or 400+ bands are from the captured CpG sequences. To confirm this, I will do PAGE purification, then re-amplify, PCR cloning and sequence a few clones.

- After elution of DNA from sheared gel with 100ul 1X TE, perform PCR (without ethanol precipitation). I included the Hd48MIP1, 2, 5 primers in addition to the AmpF/RSol.

Exp. 2 Confirmation of CpG MIP capturing experiment by PCR
Another way to confirm the result of the MIP capturing experiment is to perform PCR on the circularization reactions with target-specific PCR primers. I will use the bisulfite converted DNA as positive controls. The primers used included HD48MIP 1-3.
Template: 1ul (1:100 dilution of bifulfite converted gDNAs) 10X buffer: 2.5ul 10mM dNTP: 0.5ul 10uM Primer pair 0.5ul 50X SYBR I 0.2ul JumpStart Taq 0.25ul H2O 20ul
Total number of reactions: 4 MIP reactions x 3 primer pairs + 2 control x 3 primer pairs = 18
