Catalog No. ABIN1042376

Product Details anti-CD4 Antibody

Target: CD4

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This CD4 antibody is un-conjugated

Application: Flow Cytometry (FACS), Immunohistochemistry (Frozen Sections) (IHC (fro)), Immunocytochemistry (ICC), Immunohistochemistry (Paraffin-embedded Sections) (IHC (p))

Specificity: CD4 (Edu-2) recognizes the CD4 antigen (a 55 kD glycoprotein).

Characteristics: CD markers

Purification: Purified

Clone: Edu-2

Isotype: IgG2a

Application Details

Application Notes: Flow cytometry and immunohistochemistry using frozen and paraffin embedded tissue sections. Optimal antibody dilution should be determined by titration. CD4 (Edu-2) is used in routine blood testing for CD4+ cells and CD4/CD8 ratios (e.g. HIV/AIDS patients) or as part of panels for the detection and differentiation of certain T cell leukemias. CD4 is also used in studies of functional activity of Th-cells in bacterial and viral infections, development of auto-immune diseases, transplant rejection, immune protection in response to allergens or allergenic reactivity.

Comment:

Edu-2 is a mouse monoclonal IgG2a antibody raised against CD4.

Background: CD4 (Cluster of Differentiation 4) is a glycoprotein expressed on the surface of T helper cells, monocytes, macrophages, and dendritic cells. It was discovered in the late 1970s and was originally known as leu-3 and T4 (after the OKT4 monoclonal antibody that reacted with it) before being named CD4 in 1984. In humans, the CD4 protein is encoded by the CD4 gene. CD4 plays a role in the recognition of foreign antigens presented to T cells by MHC class II molecules. Furthermore, this antigen acts as a receptor for HIV-1 by binding the viral protein gp120. The CD4 antigen is present on most thymocytes and a subpopulation of peripheral blood T cells, called T helper cells (Th). In addition, CD4 is expressed on monocytes and weak on macrophages.
