4',6-Diamidino-2-phenylindole dihydrochloride Chemical Properties,Usage,Production
Description
DAPI is a fluorescent probe which is commonly used to stain DNA and chromosomes for fluorescent microscopy and flow cytometry applications. It forms a fluorescent complex by attaching in the minor groove of A-
Chemical Properties
Yellow Solid
Uses
DAPI is used for photofootprinting of DNA, to detect annealed probes in blotting applications by specifically visualizing the double-stranded complex and as a cell permeable fluorescent minor groove-binding probe for DNA. For staining DNA in agarose gels
Uses
Suitable for
- DNA staining in agarose gels
- analysis of changes in DNA during apoptosis
- detection of mycoplasma
- photofootprinting of DNA
- immunofluorescent staining of cells
DAPI has been used:-
- in rapid monitoring of microbial contamination
- in chromosomal banding technique
- in detection of apoptotic cells
- in fluorescence microscopy to track the DisA (DNA integritiy scanning protein) movement on Bacillus subtilis DNA
- to stain mature pollen grains(0.5 mg/ml)
Uses
4',6-Diamidino-2-phenylindole dihydrochloride is used as a cell-permeable DNA-binding dye. Binds preferentially to DNA rich in adenine and thymine.It is used in flow cytometry for measuring nuclear DNA content or for sorting isolated chromosomes.
General Description
DAPI, 4′,6-diamidino-2-phenylindole, is a blue fluorescent nucleic acid stain that fluoresces brightly upon selectively binding to the minor groove of double stranded DNA. Its selectivity for DNA and high cell permeability allows efficient staining of nuclei with little background from the cytoplasm. The excitation and emission wavelengths of DAPI-DNA complex are 360 nm and 460 nm, respectively.
Biochem/physiol Actions
Cell permeable fluorescent minor groove-binding probe for DNA. Binds to the minor groove of double-stranded DNA (preferentially to AT rich DNA), forming a stable complex which fluoresces approximately 20 times greater than DAPI alone.
storage
-20°C
