SPY555-FastAct_X - 100 stainings

SPY555-FastAct_X is a bright, far red, fluorogenic & non toxic F-actin stain based on our SPY™ dyes series. SPY555-FastAct_X’s carefully optimized actin ligand allows to label Factin in live cells with very high specificity. SPY555-FastAct_X can label very fast actin dynamics but lacks undesired F-actin stabilization side effect. The probe does not require any genetic manipulation, transfection or overexpression of fluorescent proteins. SPY555-FastAct_X is based on a low phototoxicity, bright & highly photostable SPY555 fluorophore which is far superior than fluorescent proteins. SPY555-FastAct_X enables multicolor imaging with SPY505, SPY595, PY620, SPY650, SPY700, GFP or mcherry. SPY555-FastAct_X can be imaged with standard Cy3filterset. It can be used for widefield, confocal, SIM or STED imaging of living cells and tissue. Contains 1 vial of SPY555-FastAct_X (lyophilized)
