Product Summary for Human ICAM-1/CD54 Antibody
Immunogen
Chinese hamster ovary cell line CHO-derived recombinant human ICAM-1
Extracellular domain
Extracellular domain
Specificity
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.

Scientific Data Images for Human ICAM-1/CD54 Antibody
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-a (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.
ICAM‑1/CD54 in A431 Human Cell Line.
ICAM-1/CD54 was detected in immersion fixed A431 human epithelial carcinoma cell line (left panel; positive stain) and A549 human lung carcinoma cell line (right panel; negative stain) using Sheep Anti-Human ICAM-1/CD54 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF720) at 1.7 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue). Specific staining was localized to plasma membrane. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.
Western Blot Shows Human ICAM-1/CD54 Specificity by Using Knockout Cell Line.
Western blot shows lysates of Ramos human Burkitt's lymphoma cell line and human ICAM-1/CD54 Ramos human Burkitt's lymphoma cell line (KO). 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 (HAF016). A specific band was detected for ICAM-1/CD54 at approximately 90 kDa (as indicated) in the parental Ramos human Burkitt's lymphoma cell line, but is not detectable in knockout Ramos human Burkitt's lymphoma cell line. GAPDH (Catalog # AF5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.Applications for Human ICAM-1/CD54 Antibody

Background: ICAM-1/CD54
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.
