Description

The eBio7D4 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 γ chain) to form the high affinity IL-2 receptor. 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) followed by subsequent detection with another one. eBio7D4 has been reported to block IL-2 binding but can be overcome by additional IL-2. The monoclonal antibody PC61.5 (cat. 16-0251) is recommended for in vivo studies.

Applications Reported

For research use only, not for diagnostic or therapeutic use.

Applications Tested

This eBio7D4 (7D4) antibody has been tested by flow cytometric analysis of mouse splenocyte suspensions. This can be used at less than or equal to 0.125 μg per million cells in a 100 μl total staining volume. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
