Technical datasheet
Description
The monoclonal antibody ER-HR3 is reactive to the majority of mouse monocytes and a subset of mature resident macrophages, especially those located in hemopoietic organs. Whereas all other leukocytes are ER-HR3 negative, up to 70% of circulating monocytes stain positive with this monoclonal antibody. Furthermore, about 30% of bone marrow cells express the antigen. Other ER-HR3 positive macrophages can be found in the splenic red pulp, in the mesenteric lymphoid paracortex, interfollicular areas of Peyer's patches and bone marrow. Few ER-HR3 positive cells are observed in the thymic cortex and the connective tissues of the gastro-intestinal tract, the dermis and the renal medulla. Epidermal Langerhans cells also express the antigen. The monoclonal antibody ER-HR3 can be used to identify and localize a very distinct mature tissue macrophage subpopulation found in various mouse organs and its distribution pattern is unique compared to that from other macrophage-specific antibodies. The antibody is especially suitable for ontogenic studies because ER-HR3 positive macrophages are closely related to hemopoietic islands, especially at erythropoietic sites.
Formulation
1 ml (100 µg/ml) 0.2 µm filtered antibody solution in PBS, containing 0.1% bovine serum albumin and 0.02% sodium azide.
Species
Rat IgG2c
Application
The monoclonal antibody ER-HR3 can be used for flow cytometry. Furthermore the monoclonal antibody ER-HR3 is useful for histology on both frozen and paraffin embedded sections.
Use
For flow cytometry and immunohistology dilutions to be used depend on detection system applied. It is recommended that users test the reagent and determine their own optimal dilutions. The typical starting working dilution is 1:50.
Storage and stability
Product should be stored at 4°C. Under recommended storage conditions, product is stable for one year.
