Application Notes
The RB6-8C5 antibody has been tested by flow cytometric analysis of mouse bone marrow cells and splenocyte suspensions. This can be used at less than or equal to 0.5 ug per test. A test is defined as the amount (ug) of antibody that will stain a cell sample in a final volume of 100 uL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. The RB6-8C5 antibody has also been reported for use immunoprecipitation, immunoblotting (WB) and immunohistochemical staining. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. In vivo assay was reported in scientific literature.

Background: Ly-6G (Gr-1)
Expression of Ly-6G and Ly-6C, along with other lineage markers, help define specific cell types (2,4). For example, mouse myeloid derived suppressor cells (MDSCs), which play a role in inflammation and tumor development, are further subdivided into granulocytic (G-MDSCs) or monocytic (Mo-MDSCs) (4). Mo-MDSCs express Ly-6Chi along with CD11b, but are negative for Ly-6G, whereas G-MDSCs express Ly-6Clo/int,Ly-6Ghi , and CD11b (4).
The monoclonal antibody RB6-8C5 first identified granulocyte-differentiation antigen (Gr-1) which is primarily expressed on the surface of neutrophils and immature myeloid cells, and to a lesser extent on lymphocytes and macrophages (1). Gr-1 expression increases as neutrophils mature but remains is stably expressed in monocytes (1). The RB6-8C5 reacts with both Ly-6G and Ly-6C, whereas 1A8 antibody is specific for Ly-6G (1). Antibodies against Ly-6G, such as RB6-8C5 and 1A8, are commonly used to identify a role for neutrophils in mouse models of disease as they are efficient for quickly depleting neutrophils (1). RB6-8C5, however, also targets and depletes Ly-6Chi monocytes in addition to other Ly-6G-expressing cells (1).
