DAPI es una contratinción nuclear de uso habitual para células fijas que emite fluorescencia azul cuando se enlaza con el ADN. Con el reactivo de célula fija NucBlue™ de ReadyProbes™, hemos formulado una forma de alta pureza de esta clásica tinción en una solución estable a temperatura ambiente que se suministra en un cómodo frasco cuentagotas. Para teñir las células, solo tiene que añadir dos gotas por ml.

También disponible: DAPI (4',6-diamidino-2-fenilindol, dihidrocloruro) a una concentración de 12,5X (5 µM) en agua.

• No es necesario diluir, pesar ni pipetear
• Frasco cuentagotas cómodo: solo usar dos gotas por ml
• Estable a temperatura ambiente: manténgalo a mano en su zona de trabajo o área de cultivo celular• DAPI se excita con luz UV y se detecta mediante un filtro azul/cian

Aplicaciones de adquisición de imágenes
DAPI es un colorante fluorescente clásico utilizado ampliamente para la tinción nuclear de células fijas. En microscopía de fluorescencia, DAPI se excita con luz UV y se detecta mediante un filtro azul/cián (figura 1).

Sugerencias de uso
En la mayoría de los casos, la adición de 2 gotas/ml de tinción de célula fija NucBlue™ y una incubación de 15 a 30 minutos producirá una tinción nuclear brillante. Sin embargo, puede ser necesario realizar ajustes para algunos tipos de células, condiciones y aplicaciones. En estos casos, basta con añadir más o menos gotas hasta que se obtiene la intensidad de tinción óptima.
• La tinción de células fijas NucBlue™ se excita con luz UV a 360 nm cuando se une al ADN, con un nivel máximo de emisión a 460 nm. Se detecta mediante un filtro azul/cián, como un filtro DAPI, filtros GFP azules o el conjunto de filtros del colorante Semrock BrightLine™ Alexa Fluor™ 350.
• La tinción de célula fija NucBlue™ es muy apreciada en la tinción nuclear azul para experimentos de imagen de célula fija, por lo que es idónea para su uso con aplicaciones basadas en anticuerpos.

Preguntas frecuentes

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.
