Data Example

Western Blot Detection of Mouse MARCO antibody by Western Blot. View Larger

Detection of Mouse MARCO by Western Blot. Western blot shows lysates of mouse spleen tissue. PVDF membrane was probed with 0.25 µg/mL of Goat Anti-Mouse MARCO Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2956) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). 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 known as SCARA2, is an 80 kDa type II transmembrane glycoprotein that belongs to the class A scavenger receptor family (1). Mouse MARCO consists of a 48 amino acid (aa) cytoplasmic domain, a 21 aa transmembrane segment, and a 449 aa extracellular domain (ECD) that includes a stalk region, a collagen-like region, and one SRCR domain (2). Within the ECD, mouse MARCO shares 69% and 86% aa sequence identity with human and rat MARCO, respectively. It shares 18%‑28% aa sequence identity with other mouse class A scavenger receptors CL-P1, SCARA3, SCARA5, and SR-A1/MSR. MARCO is constitutively expressed on the surface of splenic and lymph node macrophages (2, 3). Its expression is induced on Kupffer cells and alveolar macrophages by microbial infection, chemical irritants, and Th1 polarizing factors (3‑5). MARCO binds LPS, lipoteichoic acid, and other determinants on Gram positive and Gram negative bacteria (2, 6‑8). It also binds modified LDL, CpG oligonucleotides, UGRP1, silica, and TiO2 (2, 9‑11). MARCO is required for the organization of the splenic marginal zone and the interaction of local macrophages and B cells (12, 13). The SRCR domain mediates binding of MARCO to its various ligands (3, 12), while the collagen-like region mediates assembly into a disulfide-linked trimeric molecule (2, 7). MARCO ligation induces, but is not required for the production of IL-12, NO, or TNF-alpha by macrophages (5, 6, 9). MARCO knockout mice show a reduced clearance of bacterial infections, reduced mast cell mediated silicosis, increased pulmonary inflammation, and increased sensitivity to ozone induced lung damage (4, 9, 14‑16).
