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.

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 other applications.

Excitation Laser
Blue Laser (488 nm)
Green Laser (532 nm)/Yellow-Green Laser (561 nm)
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, immunohistochemical staining of acetone-fixed frozen sections5, and spatial biology (IBEX)7,8.
