Product Description

Key information: Pepstatin A Janelia Fluor® 526 is a fluorogenic green-emitting lysosome tracker and stain for live cell imaging.

Used for: fixed and live-cell imaging of lysosomes.

Application: Suitable for confocal microscopy and super resolution microscopy (SRM) including STED and 3D-SIM (structured illumination microscopy), as well as two-color lattice light-sheet microscopy.

Properties and Photophysical Data: No wash step is required when used for multicolor microscopy experiments. Excitation and emission maxima (λ) are 530 nm and 549 nm, respectively; quantum yield = 0.87; extinction coefficient = 118,000 M-1cm-1.

To measure the absorbance spectrum of this dye we recommend the following solvent: TFE plus 0.1% TFA.
