Selected for its ability to block the adhesion of HSB‑2 cells to immobilized recombinant human (rh) ICAM‑1. In direct ELISAs, approximately 5% cross-reactivity with rhICAM-3 is observed and less than 2% cross-reactivity with rhICAM-2, rhICAM-4, rhICAM-5, recombinant rat ICAM‑1, recombinant mouse ICAM‑1, and rhVCAM-1 is observed.
Polyclonal Sheep IgG
Chinese hamster ovary cell line CHO-derived recombinant human ICAM-1 Extracellular domain
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.20 EU per 1 μg of the antibody by the LAL method.
The adhesion of HSB2 human peripheral blood acute lymphoblastic leukemia cells (5 x 104 cells/well) to immobilized recombinant human ICAM-1/Fc Chimera (12.5 μg/mL, 100 µL/well) was maximally inhibited (80‑100%) by 25 μg/mL of the antibody.
Please Note: Optimal dilutions should be determined by each laboratory for each application.

Detection of Human ICAM‑1/CD54 by Western Blot.
Western blot shows lysates of HUVEC human umbilical vein endothelial cells and Ramos human Burkitt's lymphoma cell line untreated (-) or treated (+) with 10 ng/mL Recombinant Human TNF‑ alpha (Catalog # 210-TA) for 24 hours. PVDF membrane was probed with 0.2 µg/mL of Sheep Anti-Human ICAM‑1/CD54 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF720) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for ICAM‑1/CD54 at approximately 90 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Intercellular Adhesion Molecule-1 (ICAM-1) binds the leukocyte integrins LFA-1 and Mac-1. ICAM-1 expression is weak on leukocytes, epithelial and resting endothelial cells, as well as some other cell types, but expression can be stimulated by IFN-gamma, TNF-alpha, IL-1 beta and LPS. Soluble ICAM-1 is found in a biologically active form in serum, probably as a result of proteolytic cleavage from the cell surface, and is elevated in patients with various inflammatory syndromes such as septic shock, LAD, cancer and transplantation.
