FC - Quality tested

Application Notes:

Additional reported applications (for the relevant formats) include: immunohistochemistryof acetone-fixed frozen sections1, immunoprecipitation1, weakly blocks IL-2 binding1, 2, 3, and blocks IL-2 induced epithelial cell migration3.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 1.0 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Description:

CD25 is a 55 kD glycoprotein also known as IL-2 receptor α chain. It is broadly expressed on activated T and B cells, a subset of thymic and splenic dendritic cells, and intestinal epithelial cells in the rat. IL-2 is a critical cytokine involved in lymphocyte proliferation and clonal expansion. IL-2 signaling requires the high affinity IL-2 receptor composed of IL-2 receptor chains α, β, and γ. The OX-39 antibody weakly inhibits IL-2 binding to the IL-2 receptor and has been shown to block some IL-2 mediated responses in vitro.

Other Names: IL-2 receptor chain α, IL-2Rα, ?low affinity IL-2 receptor chain, Tac, p55, Ly-43
Structure: Type I membrane glycoprotein, 55 kD
Distribution: Activated T cells and B cells, thymic and splenic dendritic cells, intestinal epithelial cells
Function: Low affinity receptor for IL-2; associates with IL-2 receptor β (CD122) and γ (CD132) chains to form high affinity receptor
Ligand Receptor: IL-2
