Assessment of T7 DNA polymerase activity at the single-molecule level
In this webinar, we are going to study the activity of T7 DNA polymerase. By performing extension measurements at a constant tension, we will be able to detect and differentiate both polymerization and proof-reading events, which might be interspaced by pauses.

During this session, we will demonstrate that the LUMICKS C-Trap is an excellent tool to study the different modes of activity of a DNA polymerase while gaining insight into their occurrence, duration and probability with respect to the tension on the DNA template. Thereby, revealing many mechanistic aspects of the structure-function relationship of the molecular motor.
