CD54 (ICAM-1) Monoclonal Antibody (HA58), PE, eBioscience™, Invitrogen™

Description

• Description: The HA58 monoclonal antibody reacts with human CD54 (InterCellular Adhesion Molecule-1, ICAM-1), a 90-110 kDa transmembrane glycoprotein expressed by monocytes, lymphocytes and endothelial cells
• Expression of CD54 is upregulated on activated lymphocytes
• Interaction of CD54 with its ligand CD11a is important in the inflammatory response
• Applications Reported: The HA58 antibody has been reported for use in flow cytometric analysis
• Applications Tested: The HA58 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells
• This can be used at 5 μL (0.25 μg) per test
• A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL
• Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test
• Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser
• Filtration: 0.2 μm post-manufacturing filtered
• ICAM-1 (CD54) is an 85-110 kDa single-chain type 1 integral membrane glycoprotein with an extracellular domain of five immunoglobulin superfamily repeats, a transmembrane region and a cytoplasmic domain
• ICAM-1 has 7 potential N-linked glycosylation sites and shares considerable amino acid sequence homology with ICAM-3 (CD50) and ICAM-2 (CD102)
• ICAM-1 binds to integrins of type CD11a/CD18 (leukocyte adhesion molecule, LFA-1), or CD11b/CD18 (Mac-1) and is exploited by Rhinovirus as a receptor
• ICAM-1 is expressed by activated endothelial cells and detected on epithelial cells, fibroblasts, chondrocytes, B lymphocytes, T lymphocytes (low), monocytes, macrophages, dendritic cells and neutrophils, with lower levels that increase upon inflammation
• ICAM-1 is also detected in some carcinoma and melanoma cells
• Soluble ICAM-1 is detectable in the plasma and is elevated in patients with various inflammatory syndromes.
