Protocol to measure the membrane tension and bending modulus of cells using optical tweezers and scanning electron microscopy

Blog Article

Summary: The elastic properties of cell membranes, particularly the membrane tension and Circuit Board With Capacitor bending modulus, are known to be key regulators of cellular functions.Here, we present a correlative and integrated tool based on optical tweezers and scanning electron microscopy to accurately determine these properties in a variety of cell types.Although there are intrinsic difficulties associated with correlative experiments, we believe that the methods presented can be considered a suitable protocol for determining the elastic properties of cell membranes.
