Sigma Aldrich Fine Chemicals Biosciences BioTracker NIR694 Nuclear

Supplier:  Sigma Aldrich Fine Chemicals Biosciences SCT118

The nucleus is a membrane-enclosed organelle found in eukaryotic cells. Cell nuclei contain most of the cells genetic material organized as multiple long linear DNA molecules in complex with a large variety of proteins such as histones to form chromosomes. Traditionally DNA stains such as DAPI and Hoechst have been used for microscopy but require fixation and cannot be used for live cell imaging.The BioTracker NIR694 Nuclear Dye (DMSO) is a cell membrane-impermeable far-red dye with high selectivity for membrane compromised or dead cells. Dye staining is nuclear specific in fixed and permeabilized cells and tissue sections and does not require RNase treatment. The dye can be excited by wavelengths from 488 to 647nm and emits far red fluorescence with emission maximum at 694nm. for live cell nuclear staining we recommend the BioTracker NIR694 Nuclear Dye (Water).Spectral PropertiesAbsorbance 662nmEmission 694nm
