Detection of Human MARCO by Western Blot. Western blot shows lysates of THP-1 human acute monocytic leukemia cell line, human lung tissue, and human liver tissue untreated (-) or treated (+) with 80 nM PMA for 72 hours. PVDF membrane was probed with 0.25 µg/mL of Sheep Anti-Human MARCO Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7586) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). Specific bands were detected for MARCO at approximately 65-75 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: MARCO

MARCO (Macrophage receptor with collagenous structure; also scavenger receptor class A member 2/SR-AII) is a 65-70 kDa pattern recognition receptor/PRR that belongs to class A of the SR family, SRCR superfamily of molecules. It is expressed by macrophages, monocytes and Kupffer cells, and apparently binds to a number of microbes, including Gram+ bacteria (Staph and Strep) and Gram- bacteria (Neisseria and coliforms), plus crystalline silica. Human MARCO is a 520 amino acid (aa) type II tranamembrane glycoprotein. It contains a 43 aa cytoplasmic region and a 456 aa extracellular domain/ECD (aa 65-520). The ECD possesses one collagen-like region (aa 147-419) and an SRCR domain (aa 424-519). Human MARCO is believed to form trimers and/or multimers, and these are likely noncovalent associations. Over aa 79-520, human and mouse MARCO share 70% aa sequence identity.
