Dear Dr. Xiang-Jun,

Thank you for your quick response and helpful information.
I will try them. :)

Best regards,

Feature requests / Calculate the volume of DNA

Dear Dr. Xiang-Jun,

I am working on nanopore technology for detecting a point mutation.  In my strategy, a mutated DNA hybridizes to a probe DNA, and then the dsDNA is captured in the nanopore, and pass through pore with unzipping strands electrophoretically. I observed a difference in the unzipping duration, which caused by different DNA hybridization energy between WT and mutated DNA, as information to identify point mutation of dsDNA. At the same time, the blocking rates are changed. I wonder why that blocking rates changed. Therefore, I want to calculate the volume of DNA for a deep understanding of the current signal.

May you please guide me how can I calculate the volume of DNA?
Thank you in advance!

Sincerely yours,
