Description

CD23, also known as Fc epsilon receptor II (FcεRII), is a cell surface protein that is primarily found on B cells, but it can also be expressed on other immune cells like dendritic cells and activated macrophages. It plays a role in regulating IgE production and B cell activation.

Immunohistochemistry (IHC) is a technique used to visualize the presence, localization, and abundance of specific proteins within tissue samples. When CD23 is the target protein, IHC can be used to identify and localize cells expressing CD23 within tissue sections. This technique involves using antibodies that specifically bind to CD23, followed by visualization using a chromogenic or fluorescent detection system.

In medical diagnostics, IHC staining for CD23 can be used in various contexts, such as identifying B cell populations in lymphoid tissues, characterizing the immune cell infiltrates in inflammatory diseases, or assessing CD23 expression patterns in lymphomas or other hematologic malignancies. It can provide valuable information about the immune response and the involvement of CD23-expressing cells in various pathological processes.
