breast cancer patient peripheral blood DNA sample capture by cpg97k[edit]
gDNA extraction from blood[edit]
I used the Qiagen FlexiGene DNA kit to exact the DNA from blood. yield: 05192A18: 83.5ng/ul x 100ul; 05192B09: 72.7ng/ul x 100ul
Bisulfite conversion of patient DNA[edit]

I did the e-gel size selection and quantification with Q-PCR
quantification of PCR amplicons[edit]
I dilute the PhiX lib(10nM) to 1nM, 0.1nM, 0.025nM, 0.005nM. I dilute the sample lib with 1:10 and 1:50 ratio. Syb_FP5: ATGATACGGCGACCACCGAG Syb_RP7: CAAGCAGAAGACGGCATACGAG x 16 Template 1ul 2x iProof mix 25ul 350 syb_RP7 (100uM) 0.2ul Syb_FP5 (100uM) 0.2ul H2O 24ul 50X SYBG I 0.2ul
