Bisulfite Conversion DNA Damage Estimation
- Perform PCR with CHR8, CHR21 and CHR22
- These will be our standards
File:ZhangLab 2 2011-05-10 10hr 40min.jpg
- Need to purify CHR8, CHR21, and CHR22.
- Qubit Results(ng/ul)
- Assume amplicon length ~200bp
- CHR8-3.25ng/ul 26.72nM
- CHR21-4.39ng/ul 36.09nM
- CHR22-4.77ng/ul 39.21nM
- It is better to perform a size selection, since there are some ghosting on the gel
Determine the efficiency of bisulfite conversion
- After performing the bisulfite conversion procedures, we should perform real-time PCR of the samples and controls to determine the amount of converted human genomic DNA. Base on the we can determine the conversion efficiency.
Make Serial Dilution on Control DNA
- Create 6 STDs
Sample Name | dsDNA Concentration (pM) |
Std 1 | 20 |
Std 2 | 2 |
Std 3 | 0.2 |
Std 4 | 0.02 |
Std 5 | 0.002 |
Std 6 | 0.0002 |
Prepare qPCR Reagents
Ensure that the following reagents are completely thawed and thoroughly mixed by vortexing
- 2X KAPA SYBR FAST qPCR Master Mix
- 6 DNA Standards
- 1:1000 dilution of bisulfite converted library DNA
- Primer Mix (F+R) 1:1 ratio 1.65uM
Prepare qPCR Master Mix
CHR8 | CHR21 | CHR22 | |
2X iQ Super Mix | 20 | 20 | 20 |
Primer F+R (1.65uM) | 4.85 | 4.85 | 4.85 |
gDNA | 8 | 8 | 8 |
ddH2O | 7.15 | 7.15 | 7.15 |
Total | 40 | 40 | 40 |
Perform real-time PCR reaction in thermocycler
