Alexa Fluor® 488 anti-mouse CD11a Antibody

Product Details

Verified Reactivity

Mouse

Antibody Type

Monoclonal

Host Species

Rat

Immunogen

C57BL/6 mouse splenic secondary cytotoxic T cells

Formulation

Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.

Preparation

The antibody was purified by affinity chromatography and conjugated with Alexa Fluor® 488 under optimal conditions.

Concentration

0.5 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

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.

* Alexa Fluor® 488 has a maximum emission of 519 nm when it is excited at 488 nm.

Application Notes

The M17/4 antibody can block CD11a-mediated cellular adhesion. Additional reported applications of this antibody (for the relevant formats) include: immunoprecipitation^1,2, in vitro blocking of cell-cell adhesion^1,2 and FOXP3 expression⁵, and immunohistochemical staining of acetone-fixed frozen sections³. The M17/4 antibody does not block the binding of 2D7 antibody (Cat. No. 101002) to CD11a. The LEAF™ purified antibody (Endotoxin <0.1 EU/µg, Azide-Free, 0.2 µm filtered) is recommended for functional assays (Cat. No. 101110). For in vivo studies or highly sensitive assays, we recommend Ultra-LEAF™ purified antibody (Cat. No. 101118) with a lower endotoxin limit than standard LEAF™ purified antibodies (Endotoxin <0.01 EU/µg).
