Analysis of Force Spectroscopy by Magnetic tweezers (MT) (CAT#: STEM-MB-1258-WXH)

Introduction

Micromanipulation of individual cells and molecules is increasingly important for a wide range of biophysical research because, although ensemble biochemical analysis provides excellent qualitative and quantitative descriptions, it seldom describes phenomena at the molecular level. By observing the force spectroscopy of single molecules, the kinetics, mechanics, and variation of structure, function, and interactions can be fully explored to provide a more complete physiological picture.




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.
