CTLA4 antibody (PE)

Catalog No. ABIN1981896

Product Details anti-CTLA4 Antibody (PE)

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

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This CTLA4 antibody is conjugated to PE

Application: Flow Cytometry (FACS)

Specificity: The mouse monoclonal antibody BNI3 recognizes an extracellular domain of human CD152 / CTLA4, an approximately 45 kDa type I transmembrane protein serving as a negative regulator of T cell responses.

Cross-Reactivity (Details): Human

Purification: Purified antibody is conjugated with R-phycoerythrin (PE) under optimum conditions. Unconjugated antibody and free fluorochrome are removed by size-exclusion chromatography.

Immunogen: Human CD152-IgG heavy chain fusion protein

Clone: BNI3

Isotype: IgG2a

Application Details

Application Notes: Flow cytometry: The reagent is designed for analysis of human blood cells using 10 μL reagent / 100 μL of whole blood or 10⁶ cells in a suspension. The content of a vial (1 ml) is sufficient for 100 tests.

Comment:

The purified antibody is conjugated with R-Phycoerythrin (PE) under optimum conditions. The conjugate is purified by size-exclusion chromatography and adjusted for direct use. No reconstitution is necessary.

Restrictions: For Research Use only

Handling

Background: Cytotoxic T-lymphocyte associated protein 4,CD152 / CTLA-4 is a homodimeric transmembrane protein similar to CD28 and binding the same ligands, i.e. CD80 (B7.1) and CD86 (B7.2), but with higher affinity. Unlike CD28 with important costimulating functions, CD152 acts as an important inhibitory receptor essential for modulation of the immune system. CD152 / CTLA-4 becomes transiently expressed on activated T cells and its malfunction can cause autoimmune diseases, such as insulin-dependent diabetes mellitus, Graves disease, Hashimoto thyroiditis, celiac disease, systemic lupus erythematosus, or thyroid-associated orbitopathy.,CTLA4, GSE, GRD4
