And after I did PCR amplification (in total 5+7 cycles), the purified DNA will be about 50ng/ul in 20ul.
The Bio analyzer is attached.

Looks good Runuply: there seems to be a good nucleosome pattern on the gel picture. I think I would advice you to try to get rid of the primer peak at 65 before submitting the sample for sequencing.
