Steady-state fluorescence spectroscopy is a biophysical technique widely employed to characterize interactions between proteins in vitro. Only a few proteins naturally fluoresce in cells, but by covalently attaching fluorophores virtually all proteins can be monitored. One of the first extrinsic fluorescent probes to be developed, and that is still in use, is dansyl chloride. We have used this method to monitor the interaction of a variety of proteins, including ion channels, with the Ca2+-dependent regulatory protein calmodulin. Here we describe the preparation and use of dansyl-calmodulin (D-CaM). © 2013 Springer Science+Business Media, LLC.

Abstract
Steady-state fluorescence spectroscopy is a biophysical technique widely employed to characterize interactions between proteins in vitro. Only a few proteins naturally fluoresce in cells, but by covalently attaching fluorophores virtually all proteins can be monitored. One of the first extrinsic fluorescent probes to be developed, and that is still in use, is dansyl chloride. We have used this method to monitor the interaction of a variety of proteins, including ion channels, with the Ca2+-dependent regulatory protein calmodulin. Here we describe the preparation and use of dansyl-calmodulin (D-CaM). © 2013 Springer Science+Business Media, LLC.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
