SPY650-FastAct_X (Also known as SiR-XActin) is our most advanced live cell actin imaging probe. It labels highly 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 highly dynamic cellular actin structures but lacks undesired F-actin stabilization and toxic 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. Product contains 1 vial of SPY650-FastAct_X in lyophilised form allowing to prepare 50 ul of 1000x DMSO stock solution (100 stainings)
