Molecular tension microscopy of the LINC complex in live cells

 

Summary

We present a protocol to measure the effect of pharmacological treatments on the mechanical tension experienced by nesprins at the cytoplasmic surface of the nuclear envelope of mammalian cells in culture. We apply this protocol to MDCK epithelial cells exposed to the actin depolymerization agent cytochalasin D. To do so, we perform confocal spectral imaging of transiently expressed molecular tension sensors of mini-nesprin 2G and analyze the FRET signal from the sensors with a custom-made Fiji script.
