The ELISA kits listed below target MARCO, the symbol for the human gene, macrophage receptor with collagenous structure. The protein encoded by MARCO has a predicted amino acid length of 520, a mass of 52.7 kDa, and a membrane subcellular localization. There are currently 2 reported isoforms, as well as sites of glycosylation. MARCO may also be known by the following names: SR-A6, SCARA2, scavenger receptor class A member 2, and macrophage receptor MARCO. Orthologs of the gene, including human and mouse are available targets of several ELISA kits.
