SPY555-FastAct™

SPY555-FastAct™ is a bright, orange, fluorogenic & nontoxic F-actin stain based on our SPY™ dyes series. Its optimized structure allows to label F-actin in live cells with high specificity and low background. The unique and unmatched feature of SPY555-FastAct™ is its ability to label very fast actin dynamics. The probe does not require any genetic manipulation, transfection or overexpression of fluorescent proteins. SPY555-FastAct™ is based on our bright & photostable SPY555 fluorophore which is far superior than fluorescent proteins. SPY555-FastAct™ enables multicolor imaging with SPY505, SPY595, SPY650, SPY700, SiR or GFP. SPY555-FastAct™ can be imaged with standard TMR or Cy3 filterset. It can be used for widefield, confocal, SIM or STED imaging in living cells and tissue. Contains 1 vial of SPY555-FastAct™ (lyophilized).
