PE anti-mouse CD25 Antibody

Product Details

Verified Reactivity

Mouse

Antibody Type

Monoclonal

Host Species

Rat

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 under optimal conditions.

Concentration

0.2 mg/ml

Storage & Handling

The CD25 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

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 million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Excitation Laser

Blue Laser (488 nm)
Green Laser (532 nm)/Yellow-Green Laser (561 nm)

Application Notes

Additional reported applications (for the relevant formats) include: immunoprecipitation^1,2, in vitro blocking of IL-2 binding to low- and high-affinity receptors^1-4, growth inhibition of IL-2-dependent T-cell lines^1-4, in vivo depletion of CD25⁺CD4⁺ Treg cells^5-8,10, and immunohistochemical staining of acetone-fixed frozen sections². PC61 antibody recognizes a different epitope than 3C7 antibody (Cat. No. 101902). For in vivo studies or highly sensitive assays, we recommend Ultra-LEAF™ purified antibody (Cat. No. 102040) with endotoxin < 0.01 EU/µg, Azide-Free, 0.2 µm filtered.
