HM Janelia Fluor® 526, SE is a fluorogenic 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. NHS ester can be converted to relevant substrate for use in self-labeling tag systems, e.g. HaloTag® and SNAP-tag®.
To measure the absorbance spectrum of this dye we recommend the following solvent: TFE plus 0.1% TFA.
We also offer Janelia Fluor® conjugated antibodies and custom conjugation services with our sister company Novus Biologicals.
HaloTag is a trademark of Promega Corporation, and SNAP-tag is a trademark of New England BioLabs, Inc.
