abberior STAR 550, phalloidin, 300 units

abberior STAR 550 was developed for STED and confocal microscopy in the green-orange spectral region. Characteristic features of this dye are its exceptional photostability and brightness. abberior STAR 550 can be very effectively excited effectively excited with a 561 nm laser. For STED microscopy, abberior STAR 550 can be used most efficiently with a STED laser wavelength between 650 – 775 nm. In combination with abberior STAR BLUE, abberior STAR ORANGE, and abberior STAR RED, abberior STAR 550 enables versatile 4-color imaging across a broad spectral range. Best results are obtained with freshly prepared samples. Fluorescent dye conjugates of phalloidin are used to stain F-actin. The high specificity of phalloidin offers significant advantages over antibodies for actin labeling. Reconstitute the vial in 1.5 mL of DMF or DMSO to obtain a stock solution of 200 units/mL. We recommend diluting this stock solution 1:200 to prepare a staining solution with a final concentration of 1 unit/mL.
