1110050 100 µg $225.00       
Clone: PC61
Isotype: Rat IgG1, λ
Reactivity: Mouse
Immunogen: IL-2-dependent cytolytic mouse T-cell clone B6.1
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation: The antibody was purified by affinity chromatography, and conjugated with PE/Cy5 under optimal conditions. The solution is free of unconjugated PE/Cy5 and unconjugated antibody.
Concentration: 0.2 mg/ml
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
Application:

FC - Quality tested

Application Notes:

Additional reported applications (for the relevant formats) include: immunoprecipitation1,2, in vitro blocking of IL-2 binding to low- and high-affinity receptors1-4, growth inhibition of IL-2-dependent T-cell lines1-4, in vivo depletion of CD25+CD4+ Treg cells5-8,10, and immunohistochemical staining of acetone-fixed frozen sections2. PC61 antibody recognizes a different epitope than 3C7 antibody .

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 ≤ 0.25 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 the low affinity IL-2Rα, Ly-43, p55, or Tac. It is expressed on activated T and B cells, thymocyte subsets, pre-B cells, and T regulatory cells. In association with CD122 (IL-2Rβ) and CD132 (common γ chain), CD25 forms the high affinity signaling IL-2 receptor.

Other Names: IL-2Rα, Ly-43, p55, Tac
