Measurement of the Force–Velocity Relationship for Multiple Kinesin Motors by Magnetic tweezers (MT) (CAT#: STEM-MB-1262-WXH)

Introduction

Transport of intracellular cargo along cytoskeletal filaments is often achieved by the concerted action of multiple motor molecules. While single-molecule studies have provided profound insight into the mechano-chemical principles and force generation of individual motors, studies on multi-motor systems are less advanced.




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
