Description

Rat Monoclonal Antibody

Description: The eBio3C7 antibody reacts with mouse CD25, the 55 kDa interleukin-2 receptor a chain (IL-2Ra). CD25 is expressed by early progenitors of the T and B lineage as well as by activated mature T and B lymphocytes. By itself, CD25 binds IL-2 only with low affinity. However, CD25 associates with CD122 (IL-2 receptor beta chain) and CD132 (common gamma chain) to form the high affinity IL-2 receptor. Binding of IL-2 to both the high and low affinity classes of the IL-2 receptor is inhibited by the 3C7 antibody. CD25 plays a role in lymphocyte differentiation and activation/proliferation. The epitopes recognized by eBio3C7, PC61.5 and eBio7D4 are all different allowing for depletion with one antibody (typically PC61.5) and subsequent detection with another CD25 antibody. Applications Reported: This eBio3C7 (3C7) antibody has been reported for use in flow cytometric analysis. Applications Tested: This eBio3C7 (3C7) antibody has been tested by flow cytometric analysis of mouse splenocytes. This 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 that the antibody be carefully titrated for optimal performance in the assay of interest. eFluor™ 450 is an alternative to Pacific Blue™.

CD25 (IL2 receptor alpha chain/IL2RA) is a cytokine that plays a role in the proliferation of T and B lymphocytes. The receptor of this cytokine (IL2RA) is a heterotrimeric protein complex with a gamma chain also shared by interleukin 4 (IL4) and interleukin 7 (IL7). IL2RA, IL2R beta chain (IL2RB), and the IL2R gamma chain (IL2RG), constitute the high-affinity IL2 receptor. Homodimeric IL2RA chains result in low-affinity receptor, while homodimeric IL2RB chains produce a medium-affinity receptor. The expression of IL2 in mature thymocytes is monoallelic, which represents an unusual regulatory mode for controlling the precise expression of a single gene. IL2 is primarily produced by mature T cells. IL2 plays an important role as a growth factor, differentiation factor, and regulator of cell death. IL-2 stimulates the proliferation of B cells, augments natural killer cell activity, and inhibits granulocyte macrophage colony formation. The targeted disruption of a similar gene in mice leads to ulcerative colitis-like disease, which suggests a role in the immune response to antigenic stimuli. Mutations in this gene are associated with interleukin 2 receptor alpha deficiency.

Frequently Asked Questions (FAQs)

I am unable to analyze my cells stained with eFluor Organic Dyes today. What options do I have?

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.

What is the difference between eFluor Organic Dyes and eVolve Qdots?

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.

Are the eFluor Organic Dyes photo-labile?

As with other fluorochromes, we recommend minimal exposure to light to maintain optimal signal.
