Applications and Data
| Recommended Concentration | Sample | |
| Western Blot | 0.5 µg/mL | See below |
| Flow Cytometry | 0.25 µg/106 cells | See below |
| CyTOF-ready | Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation. | |
| Immunocytochemistry | 5-15 µg/mL | See below |
| Western Blot | |
|---|---|
 | Detection of Human CTLA‑4 by Western Blot. Western blot shows lysates of NS0 mouse myeloma cell line either mock transfected or transfected with human CTLA-4. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human CTLA‑4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-386-PB) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for CTLA‑4 at approximately 50 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1. |
| Flow Cytometry | |
 | Detection of CTLA‑4 in NS0 Mouse Cell Line Co-transfected with CTLA-4 and eGFP by Flow Cytometry. NS0 mouse myeloma cell line co-transfected with human CTLA-4 and eGFP was stained with either (A) Goat Anti-Human CTLA‑4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-386-PB) or (B) Normal Goat IgG Control (Catalog # AB-108-C) followed by Allophycocyanin-conjugated Anti-Goat IgG Secondary Antibody (Catalog # F0108). |
| Immunocytochemistry | |
 | CTLA‑4 in Human Peripheral Blood Mononuclear Cells. CTLA‑4 was detected in immersion fixed human peripheral blood mononuclear cells treated with treated with PMA and calcium ionomycin using Goat Anti-Human CTLA‑4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-386-PB) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cell surfaces. View our protocol for Fluorescent ICC Staining of Non-adherent Cells. |

| Background | CTLA-4 |
|---|---|
| background_content | Background: CTLA-4 CTLA-4 and CD28, together with their ligands B7-1 and B7-2, constitute one of the dominant costimulatory pathways that regulate T- and B-cell responses. CTLA-4 and CD28 are structurally homologous molecules that are members of the immunoglobulin (Ig) gene superfamily. Both CTLA-4 and CD28 are composed of a singleIg V‑like extracellular domain, a transmembrane domain and an intracellular domain. CTLA-4 and CD28 are both expressed on the cell surface as disulfide-linked homodimers or as monomers. The genes encoding these two molecules are closely linked on human chromosome 2. CTLA-4 was originally identified as a gene that was specifically expressed by cytotoxic T lymphocytes. However, CTLA-4 transcripts have since been found in both Th1 and Th2, and CD4+ and CD8+ T cell clones. Whereas CD28 expression is constitutive on the surfaces of 95% of CD4+ T cells and 50% of CD8+ T cells and is down regulated upon T cell activation, CTLA-4 expression is upregulated rapidly following T cell activation and peaks approximately 24 hours following activation. Although both CTLA-4 and CD28 can bind to the same ligands, CTLA-4 binds to B7-1 and B7-2 with 20‑100‑fold higher affinity than CD28. The physiological role of CTLA-4 in T cell costimulation is currently being studied. |
