Hoechst 33258 analog 2(CAT: I002781) is a blue fluorescent dye commonly used to stain DNA. These dyes bind to the minor groove of double-stranded DNA, with a preference for AT-rich sequences. They can be used to stain DNA in live or fixed cells and are often referred to as supravital stains since cells can survive their treatment. Hoechst dyes are cell-permeable and can be actively transported out of the cytoplasm by specific ATP-binding cassette transporter proteins in some cells.
