B3B4_A594_CD23_Antibody_IHCF_051519
C57BL/6 mouse frozen spleen section was fixed with 4% paraformaldehyde (PFA) for 10 minutes at room temperature and blocked with 5% FBS plus rat/mouse serum for 30 minutes at room temperature. Then the section was stained with 5 µg/ml of anti-mouse CD23 (clone B3B4) Alexa Fluor® 594 (red), anti-mouse CD3 (clone 145-2C11) Alexa Fluor® 647 (green), and anti-mouse F4/80 Antibody (Clone BM8) Alexa Fluor® 488 (blue) overnight at 4°C. The image was captured by 10X objective.

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.
