Biological Activity

Spontaneously blinking green-emitting dye; hydroxymethyl derivative of JF526. Suitable for super-resolution imaging including dSTORM, STED and single-molecule localization spectroscopy (SMLSM). The spontaneous blinking properties of HM Janelia Fluor® 526, avoids the requirement for strongly reducing dSTORM buffers. Also suitable for conventional confocal microscopy and live cell imaging.
