Image-iT™ FX Signal Enhancer ReadyProbes™ Reagent dramatically reduces background fluorescence resulting from non-specific staining during secondary detection using conjugates of streptavidin or secondary antibodies. This reagent is applied directly to slides or coverslips containing fixed and permeabilized cell or tissue samples prior to staining with fluorescent probes.

Easy protocol – apply ready-made solution using a dropper bottle
Compatible with the other steps in your immunostaining protocol
Effective with most fluorescent labels
Stable at room temperature – keep handy at your scope or cell culture area

El reactivo ReadyProbes™ para potenciador de señal Image-iT™ reduce drásticamente la fluorescencia de fondo, lo que resulta en una tinción no específica durante la detección secundaria con conjugados de estreptavidina o anticuerpos secundarios. Este reactivo se aplica directamente a los portaobjetos o cubreobjetos que contienen muestras de tejido o células fijas y permeabilizadas antes de la tinción con sondas fluorescentes.

• Protocolo sencillo: aplique el potenciador a partir de una solución preparada en un frasco cuentagotas
• Compatible con los otros pasos de su protocolo de inmunotinción
• Eficaz con muchas etiquetas fluorescentes
• Estables a temperatura ambiente: manténgalo a mano en su zona de trabajo o área de cultivo celular

Aplicaciones de imágenes celulares
El reactivo potenciador de señal Image-iT™ FX es un producto altamente eficaz para bloquear la tinción de fondo que resulta de las interacciones inespecíficas de una amplia variedad de colorantes fluorescentes con componentes celulares y tisulares. La tinción de fondo observada con conjugados fluorescentes de estreptavidina y conjugados de anticuerpos se elimina en gran medida cuando el reactivo potenciador de señal Image-iT™ FX se aplica a células fijas y permeables antes de la tinción.

Sugerencias de uso
• Aplique el reactivo potenciador de señal Image-iT™ FX directamente en los portaobjetos o cubreobjetos que contengan muestras de células o tejidos antes de la inmunotinción.
• Después del paso de fijación/permeabilización, simplemente lave y añada suficientes gotas para cubrir la muestra; luego incube durante 30 minutos y continúe con el protocolo de tinción normal.
• Se pueden realizar pasos de bloqueo adicionales después del bloqueo con el reactivo potenciador de señal Image-iT™ ReadyProbes™, según sea necesario

Para uso exclusivo en investigación. No apto para uso en procedimientos diagnósticos.

Preguntas frecuentes

I used Image-iT FX Signal Enhancer solution to get rid of nonspecific nuclear labeling with Alexa Fluor 568 secondary antibody, but I also saw a significant reduction in my specific mitochondrial antibody labeling. Why is this and what can I do?

The Image-iT FX Signal Enhancer reduces non-specific binding of dye conjugates by blocking positively-charged areas of cells or tissues that attract negatively-charged dyes. In cells after fixation, some positively-charged structures are the nuclei and mitochondria. Thus, you would expect to see a reduction in both mitochondrial and nuclear signal. The lower signal you see afterward is the specific mitochondrial signal; the fluorescence that was lost was the non-specific labeling.

Can I use the Image-iT FX Signal Enhancer instead of my normal blocking solution (BSA or serum)?

No. Image-iT FX Signal Enhancer is not a protein blocker, like BSA, normal serum, or other commercial antibody blockers. Use it as a separate step to block non-specific charge-based binding of dyes to cellular components.

I am labeling fixed and permeabilized cultured cells with an Alexa Fluor secondary antibody. My secondary-only control is showing nuclear and mitochondrial labeling, even though I did a thorough protein blocking and tried a concentration range. What can be done to minimize this non-specific binding?

This is most likely charge-based binding due to interactions of the charge on the dyes with cellular components of opposite charge. This can be blocked by using the Image-iT FX Signal Enhancer Solution which eliminates non-specific binding due to charge. The Signal Enhancer is applied as a pre-blocking step and your regular blocking regimen should be used to limit non-specific binding due to protein-protein interactions. Signal Enhancer cannot be used on live cells.

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.

I am observing high background when I analyze my click-labeled samples. What is causing this and what can I do to reduce the background?

The click reaction is very selective between an azide and alkyne. No other side reactions are possible in a biological system. Any non-specific background is due to non-covalent binding of the dye to various cellular components. The Select FX Signal Enhancer is not effective at reducing non-specific charge-based binding of dyes following the click reaction; we do not recommend its use with the Click-iT detection reagents. The best method to reduce background is to increase the number of BSA washes. You should always do a no-dye or no-click reaction control under the same processing and detection conditions to verify that the background is actually due to the dye and not autofluorescence. You can also perform the complete click reaction on a carrier solvent-only, no EdU or no-EU control to verify the specificity of the click reaction signal.

To bridge the gap between two-dimensional cell culture and tissue, various three-dimensional (3-D) cell culture approaches have been developed for the investigation of cardiac myocytes (CMs) and cardiac fibroblasts (CFs). However, several limitations still exist. This study was designed to develop a cardiac 3-D culture model with a scaffold-free technology ... More
