Bisulfite Biotin-Binding
- Ran gel for Bisulfite-converted bead-bound DNA and normal bead-bound DNA:
File:04072011 Low Input Bisulfite FAILED.jpg
- Bisulfite-converted libraries did not work.
- DNA was definitely attached to beads, as normal amplification worked.
- DNA must have been detached
- Can we modify the experiment to still allow attachment to beads?
- According to Invitrogen website [1], bead-detachment can occur when:
- Heat in formamide or basic solution at 95 for 2 min or 65 for 5 min
- Boil beads
- According to Invitrogen website [1], bead-detachment can occur when:
- We can skip desulfonation step according to a published paper: [2]
- Can use 30 min at 95 C in initial reaction
