Invitrogen™ Eos Monoclonal Antibody (ESB7C2), eFluor™ 660, eBioscience™
Description
Description: This ESB7C2 monoclonal antibody reacts with mouse Eos (IKZF4, ZNFN1A4), a zinc finger transcription factor and member of the Ikaros family. Among the Ikaros family of proteins, Eos has the highest homology with Helios. Eos can homodimerize with itself and form heterodimers with Ikaros. Eos was first identified in the nervous system and was cloned from astrocytes. Later, Eos was found to be involved in the regulation of osteoclast differentiation. Eos has also been reported to be involved in negatively regulating gene expression in Foxp3-expressing regulatory T cells in mice. Applications Reported: This ESB7C2 antibody has been reported for use in intracellular staining followed by flow cytometric analysis. Applications Tested: This ESB7C2 antibody has been tested by intracellular staining and flow cytometric analysis of mouse splenocytes using the using the Foxp3/Transcription Factor Buffer Set (Product # 00-5523-00) and protocol. Slight modifications in the protocol using this antibody have been demonstrated to improve the staining resolution. We recommend the staining time of minimum 60 minutes and additional washes after the fixation (3 times) and staining steps (twice). This antibody can be used at less than or equal to 1 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended t...

Frequently Asked Questions (FAQs)
Our options will depend on the samples you are analyzing.
If cell viability is not critical, you can store your stained samples at 4 degrees C or on ice overnight in the dark and analyze the following day.
For samples stained with eFluor organic fluorochromes, we recommend that cells be suspended in 100 uL of Flow Cytometry Staining Buffer (Cat. No. 00-4222) and 100 uL of eBioscience IC Fixation Buffer (Cat. No. 00-8222); samples can be incubated for up to 3 days at 4 degrees C in the dark. Alternatively, the 1-step Fix/Lyse Solution (Cat. No. 00-5333) can be used. This is a great option when working with whole blood but also works for other cell types.
Yes, the eFluor Organic fluorochromes can be used for intracellular staining. The eFluor organic fluorochromes maintain bright signal and require minimal changes in compensation when fixed with eBioscience IC Fixation Buffer (Cat. No. 00-8222-49) and Permeabilization Buffer (Cat. No. 00-8333-56) or 1-step Fix/Lyse Solution (Cat. No. 00-5333-54, 00-5333-57) (as compared to live cells).
Yes, in-house studies have demonstrated that the eFluor 660 fluorochrome is recognized by Anti-Cy5/Alexa Fluor 647 beads. Side by side studies with Alexa Fluor 647 versus eFluor 660 conjugated antibodies have demonstrated comparable results.
The eFluor Organic Dyes (eFluor 450, APC-eFluor 780, PerCP-eFluor 710, eFluor 710) are conventional fluorochromes. In contrast, the eVolve line of products are Quantum dots.
As with other fluorochromes, we recommend minimal exposure to light to maintain optimal signal.
