Description: This G7.43.1 monoclonal antibody reacts with mouse embigin (gp70), a single transmembrane glycoprotein that is a member of the Ig superfamily similar to basigin and EMMPRIN. It contains two Ig domains thought to be involved in cellular adhesion and tissue remodeling. Expression of embigin is high before day 10 in fetal development. In the adult it is expressed on myeloid cells and T cells but not B cells. During hematopoeisis, embigin is expressed on HSCs and CLPs (common lymphoid progenitors) but absent on pro- and pre-B cells. In recent studies Pax 5 has been shown to repress embigin expression.
