Product Specifications
Immunogen
This antibody was raised in Lou-M rats using a popliteal lymph node immunisation and fusion protocol
Specificity
This antibody is specific for murine Ly6G, a a 21-25 kDa glycosylphosphatidylinositol (GPI)-linked protein expressed by the myeloid-derived cells in a tightly developmentally-regulated manner in the bone marrow. Monocytes express Ly6G transiently during bone marrow development, while Ly6G expression in granulocytes and peripheral neutrophils directly correlates with the cell's level of differentiation and maturation. This hallmark makes Ly6G a good marker for these particular cell populations. Ly6G has also been implicated in the development of antitumor responses.

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).
