CD4 antibody

Catalog No. ABIN2689230

Product Details anti-CD4 Antibody

Target: CD4

Reactivity: Mouse

Host: Rat

Clonality: Monoclonal

Conjugate: This CD4 antibody is un-conjugated

Application: Flow Cytometry (FACS), Immunohistochemistry (Frozen Sections) (IHC (fro)), Immunohistochemistry (Formalin-fixed Sections) (IHC (f)), Immunohistochemistry (Zinc-fixed Sections) (IHC (zinc))

Brand: BD Pharmingen™

Characteristics: The RM4-5 monoclonal antibody specifically binds to the CD4 (L3T4) differentiation antigen expressed on most thymocytes, subpopulations of mature T lymphocytes (i.e., MHC class II-restricted T cells, including most T helper cells and immunosuppressive regulatory T cells), and a subset of NK-T cells. CD4 has also been reported to be detected on pluripotent hematopoietic stem cells, bone marrow myeloid and B-lymphocyte precursors, intrathymic lymphoid precursors, and a subset of splenic dendritic cells. CD4 has been reported to be expressed on the plasma membrane of mouse egg cells and is involved in adhesion of the egg to MHC class II-bearing sperm. CD4 is an antigen coreceptor on the T-cell surface which interacts with MHC class II molecules on antigen-presenting cells. It participates in T-cell activation through its association with the T-cell receptor complex and protein tyrosine kinase lck. Purified RM4-5 mAb has been reported to block the binding of FITC-conjugated anti-mouse CD4 clones GK1.5 and H129.19, but not the RM4-4 clone. Immunohistochemical staining of mouse CD4. Frozen sections of normal mouse spleen were stained with the anti-mouse CD4 antibody clone RM4-5. CD4+ T lymphocytes can be identified by the intense brown labeling of their cell surface membranes. Amplification 20X.
