Application
Le DAPI est nettement plus sensible que le bromure d′éthidium pour marquer l′ADN dans les gels d′agarose.
Le DAPI est nettement plus sensible que le bromure d′éthidium pour marquer l′ADN dans les gels d′agarose. Il peut être utilisé dans le photofootprinting de l′ADN, pour détecter les sondes hybridées dans les applications sur membranes en permettant la visualisation spécifique des complexes double-brins, et pour évaluer les changements de l′ADN et de son contenu lors de l′apoptose par cytométrie en flux. La coloration par DAPI est également une méthode sensible et spécifique de détection des mycoplasmes.
DAPI is a fluorescent dye that binds selectively to double-stranded DNA and forms strongly fluorescent DNA-DAPI complexes with high specificity. It is commonly used to detect mycoplasma in cell culture via fluorescence microscopy.
Biochem/physiol Actions
Sonde fluorescente pour l′ADN qui se lie dans le petit sillon, capable de pénétrer dans les cellules. Se lie au petit sillon d′ADN double brin (préférentiellement à l′ADN riche en AT), formant un complexe stable dont l′intensité de fluorescence est environ 20 fois plus élevée que celle du DAPI non lié.
The fluorescent dye DAPI binds selectively to DNA and forms strongly fluorescent DNA-DAPI complexes with high specificity. DAPI, once added to tissue culture cells, is rapidly taken up into cellular DNA, yielding highly fluorescent nuclei and no detectable cytoplasmic fluorescence. When the cells are contaminated with Mycoplasmas, characteristic discrete fluorescent foci are readily detected over the cytoplasm and sometimes in intercellular spaces.

Late-phase long-term potentiation (L-LTP) in hippocampus, thought to be the cellular basis of long-term memory, requires new protein synthesis. Neural activity enhances local protein synthesis in dendrites, which in turn mediates long-lasting synaptic plasticity. Ca2+/calmodulin-dependent protein kinase IIα (CaMKIIα) is
