DAPI Staining Kit

• Catalog Number: orb219885
• Category: Tools
• Description: DAPI (4',6-diamidino-2-phenylindole) is a blue-fluorescent DNA stain that exhibits -20-fold enhancement of fluorescence upon binding to AT regions of dsDNA.It is used extensively in fluorescence microscopy. As DAPI can pass through an intact cell membrane, it can be used to stain both live and fixed cells, though it passes through the membrane less efficiently in live cells and therefore the effectiveness of the stain is lower.
• Tested applications: ICC, IF
• Storage: Store at -20°C for one year.
• Note: For research use only
• Expiration Date: 12 months from date of receipt.

Immunofluorescent analysis staining in HeLa cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with the primary antibody in 3% BSA-PBS and incubated overnight at 4 °C in a humidified chamber. Cells were washed with PBST and incubated with a FITC-conjugated secondary antibody (green) in PBS at room temperature in the dark. DAPI was used to stain the cell nuclei (blue).
