細胞イメージングアプリケーション
DAPIは、固定細胞の核染色に幅広く使用される従来の蛍光色素です。蛍光顕微鏡では、DAPIはUV光で励起され、青/青緑フィルターで検出されます(図1)。

使用方法のご提案
ほとんどの場合、2滴/mLのNucBlue™固定細胞染色剤を用い、15~30分のインキュベーションを行うことで明るい核染色が得られますが、一部の細胞タイプ、条件およびアプリケーションでは最適化が必要になる場合があります。このような場合は、最適な染色強度が得られるまで、より多くまたは少ない滴を加えるだけです。
•NucBlue™固定細胞染色剤は、DNAに結合した場合に360 nmでUV光によって励起され、460 nmで最大の蛍光を示します。DAPIフィルター、青色GFPフィルター、またはSemrock BrightLine™ Alexa Fluor ™350色素フィルターセットなどの青色/青緑色フィルターを介して検出されます。
•固定細胞イメージング実験で好まれる青色核染色剤であるNucBlue™固定細胞染色剤は、抗体ベースのアプリケーションでの使用に最適です。

よくあるご質問(FAQ)

My DAPI labeled samples have a strong blue background signal immediately after mounting. What can I do to fix this?

Some mounting medias can have strong blue autofluorescence. If you are seeing a high blue background, it could be coming from the mountant. Try labeling the sample and view it before (using a wet mount in buffer) and after mounting to determine if the background signal is coming from the mounting media or the sample itself.

Do you offer an alternative for the discontinued 3-Germ Layer ICC Kit (Cat. No. A25538)?

We do not have a direct alternative for the discontinued 3-Germ Layer ICC Kit (Cat. No. A25538). However, we do have alternative primary and secondary antibodies, as well as reagents, that can be used for trilineage differentiation. Please note that we have not internally validated the use of all these reagents together.

We recommend the following primary antibodies:

Alpha-Smooth Muscle Actin Monoclonal Antibody (1A4 (asm-1)) (Cat. No. MA5-11547)

alpha-Fetoprotein Monoclonal Antibody (AFP3) (Cat. No. 14-6583-80)

beta-3 Tubulin Monoclonal Antibody (2G10) (Cat. No. MA1-118)

We recommend the following secondary antibodies:

Goat anti-Mouse IgG2a Cross-Adsorbed, Alexa Fluor 555 (Cat. No. A21137)

Goat anti-Mouse IgG2a Cross-Adsorbed, Alexa Fluor 594 (Cat. No. A21135)

Can I use the ReadyProbes reagents for flow cytometry?

This is not recommended. The ReadyProbes reagents were developed for imaging applications whereas the Ready Flow reagents were optimized for flow cytometry.
