Reactivity | Human |
Clonality | Monoclonal |
Brand: | Exbio |
Product no.: | 12-452-C025 |
Product type: | Primary antibodies |
Host species: | Mouse |
Product name: | Mouse Monoclonal to CD50 / ICAM-3 |
Antigen: | CD50 |
Clonality: | Monoclonal |
Clone: | MEM-04 |
Isotype: | IgG1 |
Immunogen: | Leukocytes of a patient suffering from LGL-type leukemia. |
Format: | low endotoxin |
Specificity: | The antibody MEM-04 reacts with CD50 (ICAM-3), a 120-130 kDa type I membrane protein (immunoglobulin supergene family) expressed on leukocytes, endothelial cells and Langerhans cells; it is negative on platelets and erythrocytes. The MEM-04 blocks DC-SIGN (CD209) binding to ICAM-3 (epitope in D1). |
Categories: | CD and Related Antigens (Human) |
Concentration: | 1 mg/ml |
Storage buffer: | Azide free phosphate buffered saline (PBS), approx. pH 7.4; 0.2 μm filter sterilized. Endotoxin level is less than 0.01 EU/μg of the protein, as determined by the LAL test. |
Storage / stability: | Store at 2-8°C. Do not freeze. Do not use after expiration date stamped on vial label. |
Background: | CD50 (intracellular adhesion molecule 3, ICAM-3) is a transmembrane glycoprotein expressed by leukocytes, that serves as a counter-receptor for the lymphocyte function-associated antigen (LFA)-1 integrin. Besides functioning as an adhesive molecule that mediates e.g. the contact between T cells and antigen presenting cells, ICAM-3 regulates affinity of LFA-1 for ICAM-1 and induces T cell activation and proliferation. ICAM-3 plays an essential role in the initiation of the immune response both on T cells and antigen presenting cells and interacts also with CD209 (dendritic cell-specific ICAM-3-grabbing nonintegrin, DC-SIGN), a C-type lectin of dendritic cells and macrophages; this process is involved in dialogue between dendritic cells and granulocytes. |
Purity: | > 95% (by SDS-PAGE) |
Purification: | Purified by protein-A affinity chromatography |
