SPY650-FastAct_X is our most advanced live cell actin imaging probe. It labels very dynamic actin filaments as well as the more static ones. SPY650-FastAct_X is a bright, fluorogenic, non toxic, cell permeable and highly specific live cell probe for fluorescence imaging of actin. SPY650-FastAct_X can label very fast actin dynamics but lacks undesired F-actin stabilization side effects. It does not require any transfection and works just by adding the probe to the cells and perform imaging a couple of hours later.
