The glycoprotein CD93 binds to C1q, the subunit of the complement protein, mannose binding lectin and pulmonary surfactant protein A. CD93 is predicted to play a role in the clearance of apoptotic cells. Expression of CD93 is confined to myeloid cells with higher expression on monocytes than neutrophils, eosinophils, platelets and endothelial cells. Expression on DC's is downregulated upon maturation. Additionally, CD93 has been shown to define an early bone marrow stem cell population of hematopoietic and hepatic precursors. \u003c\/p\u003e\u003cp\u003eThe monoclonal antibody R139 blocks C1q-mediated enhancement of phagocytosis. \u003c\/p\u003e\u003cp\u003eCD93 can be shed from the cell surface. This phenomenon can be measured using R3 antibody as detection with R139 as capture to detect soluble CD93 by ELISA. The epitope for R139 resides in the EGF domains.\u003c\/p\u003e\u003cp\u003eApplications Reported:  This R139 antibody has been reported for use in flow cytometric analysis, immunoprecipitation, immunoblotting (WB) under nonreducing conditions, ELISA, and immunohistochemistry of formalin-fixed paraffin embedded tissue.\u003c\/p\u003e\u003cp\u003eApplications Tested: This R139 antibody has been tested by flow cytometric analysis of human peripheral blood cells. This can be used at less than or equal to 0.5 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells\/test. The R139 antibody has been tested by immunohistochemistry of formalin-fixed paraffin embedded human tissue using low pH antigen retrieval and can be used at less than or equal to 40 µg\/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.\u003c\/p\u003e\u003cp\u003ePurity: Greater than 90%, as determined by SDS-PAGE.\u003c\/p\u003e\u003cp\u003eAggregation:  Less than 10%, as determined by HPLC.\u003c\/p\u003e\u003cp\u003eFiltration: 0.2 µm post-manufacturing filtered.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003eFor Research Use Only.
