General description
DAPI（4',6-ジアミジノ-2-フェニルインドールジヒドロクロリド）は、DNAと結合する細胞透過性の蛍光色素です。
熱または超音波処理が必要になる場合があります。室温または 4 ℃ で暗所に保存した溶液は、2 ～ 3 週間安定です。
Application
DAPIは、アガロースゲル中のDNA染色において、エチジウムブロマイドよりも数倍高感度です。
DAPIはアガロ-スゲル中の臭化エチジウムによるDNA染色よりも数倍高い感度を示します。DNAの蛍光フットプリンティングにも使用可能で、また、二本鎖形成を特異的に可視化するためブロッティングの際にアニ-リングしているプロ-ブを検出でき、フロ-サイトメトリ-を使用することでアポト-シス中のDNA変化の調査やDNA量の分析が可能です。DAPI染色は、マイコプラズマに対する高感度かつ特異的な検出方法であることも示されています。
Biochem/physiol Actions
細胞透過性を有し、副溝に結合するDNA用蛍光プロ-ブです。二本鎖DNAの副溝に(ATリッチなDNAを優先して)結合し、DAPI単独よりも約20倍強い蛍光を発する安定な複合体を形成します。

Can the stain concentration be used for staining fish scales and any animal cells for ICC?
1 回答-
Yes, DAPI can be used to stain fish scale nuclei. While specific data regarding the concentration and duration for staining fish scale nuclei is not available, it is suggested to start with a working concentration of around 0.5 mg/ml and optimize the staining for each specific cell type, as different cells may uptake the dye at varying rates. It is also advisable to try staining at both higher and lower concentrations. For staining mammalian cells, lower concentrations are typically used.

How should D9542, 4´,6-Diamidino-2-phenylindole dihydrochloride (DAPI), be stored once in solution, and for how long would it be good?
1 回答-
Solutions stored in the dark at room temperature have been stable for 2-3 weeks, but solutions exposed to light for the same time period have shown considerable degradation. At 1 mg/mL, solutions are stable in the dark at 2-8 °C for several weeks. For long-term storage, the solutions can be divided into aliquots and stored at -20 °C.
