SPY505-DNA

SPY505-DNA is a bright green & non toxic live cell nuclear stain based on our SPY dyes series. Its optimized structure allows quick labeling of DNA in live & fixed cells with high specificity and very low background. SPY505-DNA stains the nuclei of live or fixed cells without the need for genetic manipulation or overexpression of fluorescent proteins. Its absorbance and emission are similar to fluorescein or Alexa488. SPY505-DNA enables multicolor imaging with SPY555, SPY595, SPY650, SPY700, SiR, RFP or mcherry. SPY505-DNA can be imaged with standard fluorescein (FITC) or YFP filtersets. It can be used for widefield, confocal, SIM or STED imaging in living or fixed cells and tissue. Contains 1 vial of SPY505-DNA (lyophilized).
