Western blot shows lysates of human erythrocytes and human heart tissue. PVDF membrane was probed with 0.2 µg/mL of Sheep Anti-Human ICAM-4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7179) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for ICAM-4 at approximately 42 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Human ICAM-4 by Simple Western^TM.

Simple Western lane view shows lysates of human heart tissue, loaded at 0.2 mg/mL. A specific band was detected for ICAM-4 at approximately 48 kDa (as indicated) using 10 µg/mL of Sheep Anti-Human ICAM-4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7179) followed by 1:50 dilution of HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Detection of ICAM-4 in Human Red Blood Cells by Flow Cytometry.

Human red blood cells (erythrocytes) were stained with Sheep Anti-Human ICAM-4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7179, filled histogram) or isotype control antibody (Catalog # 5-001-A, open histogram), followed by Allophycocyanin-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # F0127).

Background: ICAM-4

ICAM-4 (intercellular adhesion molecule 4; also Landsteiner-Wiener glycoprotein and CD242) is a 42 kDa member of the ICAM family, Ig superfamily of proteins. It is expressed on erythrocytes and erythroblasts, and serves as a receptor for LFA-1, Mac-1, and CD11c/CD18, plus alpha4 beta1 and alpha-V containing integrins. ICAM-4 is suggested to bind to Mac-1 on macrophages, allowing for its phagocytosis in senescence. Mature human ICAM-4 is a 249 amino acid (aa) type I transmembrane glycoprotein. It possesses a 218 aa extracellular region (aa 23-240) that contains two C2-type Ig-like domains (aa 62-124 and 146-217), and a 10 aa C-terminal cytoplasmic tail. ICAM-4 may form 85 kDa homodimers. There are three potential isoform variants. One shows a five aa substitution for aa 233-271, a second contains a 15 aa substitution for aa 14-29, and a third possesses a 141 aa substitution for aa 132-271. Over aa 31-240, human ICAM-4 shares 71% aa identity with mouse ICAM-4.
