CTLA4 antibody

Catalog No. ABIN2688988

Product Details anti-CTLA4 Antibody

Target: CTLA4 (Cytotoxic T-Lymphocyte-Associated Protein 4 (CTLA4))

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This CTLA4 antibody is un-conjugated

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

Brand: BD Pharmingen™

Characteristics: Reacts with the "cytolytic T lymphocyte-associated antigen", CTLA-4. CTLA-4 is transiently expressed on activated CD28+ T cells and binds to CD80 and CD86 present on antigen presenting cells (APC) with high avidity. This interaction appears to deliver a negative regulatory signal to the T cell. There are recent reports that indicate that CTLA-4 is also expressed on B cells when cultured with activated T cells, suggesting a possible role of CTLA-4 in the regulation of B-cell response. Immobilized BNI3.1 enhances T-cell proliferation induced by CD3 and CD28. Recent studies have showed that CD152 can be expressed by regulatory T (Treg) cells. It has been found this antibody can stain the intracellular CD152 on the Treg cells after fixation and permeabilization of cells. Immunohistochemical staining of CTLA-4 positive cells. Frozen section of normal human tonsil was reacted with the BNI3.1 antibody. Activated T- and B-lymphocytes positive for CTLA-4 can be identified by the intense brown labeling of their cell membranes. Amplification 40X.
