breast cancer patient peripheral blood DNA sample capture by cpg97k

gDNA extraction from blood

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

Qiaquick purification and e-gel size selection. 

PCR amplification with AmpF6.3NH2/AmpR6.3NH2 and dUTP:dNTP 1:40

I did the dUTP_PCR with template from the Qiaquick purified captured targets of 97k. For each targets, I did 200ul PCR reaction.
