CD11b antibodies, human

CD11b antibodies, human

Clone: REA713 | Dilution: 1:50
Clone REA713 recognizes the human CD11b antigen (Mac-1 α; integrin αM chain), which is part of the CD11b/CD18 heterodimer (Mac-1 α, Mβ2 integrin), also known as the C3 complement receptor. It functions as a receptor for complement (C3bi), fibrinogen, or clotting factor X. In humans, CD11b is strongly expressed on myeloid cells and weakly expressed on NK cells and some activated lymphocytes as well as on microglia in the brain.
Additional information: Clone REA713 displays negligible binding to Fc receptors.

Alternative Names

integrin αM, Mac-1 α, Integrin alpha-M, CR3A

REAfinity clone is tested against different known clones, in a blocking experiment, to identify whether they recognize completely overlapping (++), partially overlapping (+), or completely different epitopes (-). In a blocking experiment, cells are incubated with an excess of purified unconjugated REAfinity clone followed by staining with conjugated form of the other known clones.
