Negative Isotype Controls
- DAPI is a cell permeable fluorescent compound that is able to stain the DNA of eukaryotic and prokaryotic cells by binding with high affinity to the minor groove of AT-rich DNA sequences. When DAPI is bound to DNA and excited by an ultraviolet light source, blue fluorescent emission can be detected with maximum emission at at 461 nm. PureBlu DAPI has a characteristic Stokes shift of approximately 100 nm, which makes this dye an optimal choice when good spectral separation is desired. PureBlu DAPI is compatible with fixed and unfixed cells.
