- Amplification failed with Pfu cx polymerase
Perform bisulfite conversion on 6ng, 1.2ng, and 600pg of gDNA using Zymo’s direct kit
Objective
- test the feasibility of using zymo direct kit to perform bisulfite conversion on 100 cells, 200 cells and 1000 cells worth of DNA and perform 2nd strand synthesis to make sequencing library with regular nextera kit
- Test wether we need to perform heat denaturing on the bisulfite converted library to ensure we have single stranded DNA after conversion with 3 set of samples.
Protocol
- Setup 3 sets of reactions (Set 1, 2 & 3)
