Measurement of the Stall Torque of the Flagellar Motor in Escherichia coli by Magnetic tweezers (MT) (CAT#: STEM-MB-1260-WXH)

Introduction

The flagellar motor drives the rotation of flagellar filaments, propelling the swimming of flagellated bacteria. The maximum torque the motor generates, the stall torque, is a key characteristic of the motor function.




Principle

Magnetic tweezers (MT) are scientific instruments for the manipulation and characterization of biomolecules or polymers. These apparatus exert forces and torques to individual molecules or groups of molecules. It can be used to measure the tensile strength or the force generated by molecules.

Applications

Study of mechanical properties of biological macromolecules like DNA or proteins in single-molecule experiments.
Study of the rheology of soft matter.
Study of force-regulated processes in living cells.

Procedure

1.Sample preparation
2.Force Calibration
3.Measurement
4.Analysis
