1108085 25 µg $90.00       
1108090 100 µg $210.00       
Clone: B3B4
Isotype: Rat IgG2a, κ
Reactivity: Mouse
Immunogen: Complex of IgE with Fcε receptor isolated from the mouse B hybridoma cell line O1.2B2
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation: The antibody was purified by affinity chromatography and conjugated with PerCP/Cy5.5 under optimal conditions. The solution is free of unconjugated PerCP/Cy5.5 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:

The B3B4 antibody is useful for blocking IgE activity in vivo. Additional reported applications (for the relevant formats) include: immunoprecipitation1, immunofluorescence microscopy, in vitro and in vivo blocking of ligand binding2-4, and immunohistochemical staining of acetone-fixed frozen sections5.

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

* PerCP/Cy5.5 has a maximum absorption of 482 nm and a maximum emission of 690 nm.

Description:

CD23 is a 45 kD protein also known as low affinity IgE Fc receptor, FcεRII, BLAST-2, Ly-42, or B6. It is a member of the Ig family, expressed on conventional B (but not B-1) cells and follicular dendritic cells. CD23 responds to high levels of IgE by downregulating IgE secretion.

Other Names: FcεRII, IgE Fc Receptor, BLAST-2, Ly-42, B6
Structure: C-lectin family, type II transmembrane glycoprotein, 45 kD
Distribution: B cells, follicular dendritic cells
Function: Regulates B cell activation
Ligand Receptor: IgE, CD19/CD21/CD81
