For conjugation experiments, perform an additional desalting step using Zeba Spin Desalting Columns (7K MWCO, 0.5 mL, Product #89882).

Target Information

CD163 (M130 antigen, Ber-Mac3, Ki-M8, SM4) is a 130 kDa membrane glycoprotein belonging to the scavenger receptor cysteine-rich superfamily.
It acts as a receptor for the hemoglobin-haptoglobin complex, protecting tissues from oxidative damage and aiding in iron recycling via endocytosis and heme breakdown.

CD163 is expressed on human monocytes and macrophages, particularly in the late phase of inflammation. It is found on all circulating monocytes and most tissue macrophages, except those in mantle zones, germinal centers, interdigitating reticulum cells, and Langerhans cells.

Expression is upregulated by IL-10, IL-6, and dexamethasone, while LPS and PMA induce shedding of CD163 from the cell surface. CD163 binds hemoglobin/haptoglobin complexes in a calcium- and pH-dependent manner, showing higher affinity for multimeric HP1F-type complexes. It also triggers intracellular signaling cascades involving tyrosine kinase-dependent calcium mobilization, inositol triphosphate production, and secretion of IL-6 and CSF1.
