SpecificityThis antibody recognises the integrin alphax subunit, a 150kD glycoprotein expressed by macrophages, monocytes, granulocytes and NK cells. The antigen is also expressed by hairy cell leukaemia cells. Ligands for CD11c are ICAM 1, iC3b, and fibrinogen. The molecule has a role in mediating adherence of granulocytes and monocytes to endothelium and fibrinogen.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application notesFlow Cyt: Use 10µl of working dilution for 106 cells. Suggested working dilution is neat - 1/10.
Not tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
FunctionIntegrin alpha-X/beta-2 is a receptor for fibrinogen. It recognizes the sequence G-P-R in fibrinogen. It mediates cell-cell interaction during inflammatory responses. It is especially important in monocyte adhesion and chemotaxis.
Tissue specificityPredominantly expressed in monocytes and granulocytes.
Sequence similaritiesBelongs to the integrin alpha chain family. Contains 7 FG-GAP repeats. Contains 1 VWFA domain.
DomainThe integrin I-domain (insert) is a VWFA domain. Integrins with I-domains do not undergo protease cleavage.
