C1qRp(CD93)

Mouse IgM, κ

C1q-binding protein

The immunogen used to raise R3 was C1q-binding protein preparation as described. Human C1qRp is a 631 a.a. protein (~66.5 kD) protein that is highly expressed on monocytes/macrophages, neutrophil granulocytes but not on T and B lymphocytes. C1qRp binds C1q, the recognition subunit of the first component (C1) of the complement pathway, as well as MBL (Mannose-binding-lectin) and SPA (Pulmonary Surfactant Protein A). Human C1qRp is involved in the C1q-mediated enhancement of phagocytosis. R3 is suitable to detect C1qRp expression on cells of myeloid lineage by flow cytometry, C1qRp in cellular lysates by Western blotting or immunoprecipitation. Pretreatment of monocytes with R3 neutralizes C1q-mediated enhancement of phagocytosis. In addition, when immobilized, R3 mimics C1q- MBL- or SPA-mediated enhancement of phagocytosis as reported. CDw93 (C1qRp) has been reported to define a human stem cell population with hematopoietic and hepatic potential.
