Probing distance and electrical potential within a protein pore with tethered DNA.
- Abstract:
-
DNA molecules tethered inside a protein pore can be used as a tool to probe distance and electrical potential. The approach and its limitations were tested with alpha-hemolysin, a pore of known structure. A single oligonucleotide was attached to an engineered cysteine to allow the binding of complementary DNA strands inside the wide internal cavity of the extramembranous domain of the pore. The reversible binding of individual oligonucleotides produced transient current blockades in single ch...

Clearance
-
Some thesis volumes scanned as part of the digitisation scheme funded by Dr Leonard Polonsky are currently unavailable due to sensitive material or uncleared third-party copyright content. We are attempting to contact authors whose theses are affected.
Alternative access to the full-text
