Detects rat ICAM-1/CD54 in direct ELISAs and Western blots. In direct ELISAs, approximately 40% cross-reactivity with recombinant mouse (rm) ICAM-1 and 5% cross-reactivity with recombinant human (rh) ICAM-1, rhICAM‑3, and rmICAM‑2 is observed.

Mouse myeloma cell line NS0-derived recombinant rat ICAM-1/CD54 Gln28-Thr493 Accession # Q00238
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.
<0.10 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 Rat ICAM-1 Fc Chimera (Catalog # 583-IC, 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. General Protocols are available in the Technical Information section on our website.
Detection of Rat ICAM‑1/CD54 by Western Blot. Western blot shows lysates of rat liver tissue. PVDF membrane was probed with 0.2 µg/mL of Goat Anti-Rat ICAM‑1/CD54 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF583) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). 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.
ICAM‑1/CD54 in Rat Brain. ICAM‑1/CD54 was detected in perfusion fixed frozen sections of rat brain using Goat Anti-Rat ICAM‑1/CD54 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF583) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Intercellular Adhesion Molecule-1 (ICAM-1, CD54), 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 lipolysaccharide (LPS). Rat and human ICAM-1 share approximately 52% amino acid identity. Rat and mouse ICAM-1 share approximately 52% amino acid identity.
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, leukocyte adhesion deficiency syndrome (LAD), cancer, and transplantation.
