|Target/Specificity||Mouse anti-Human CD80 antibody, clone MEM-233 recognizes human CD80, also known as B7-1, a ~60kDa type 1 trans-membrane protein expressed of macrophages, dendritic cells (Munroet al.1994) and activated B-cells (Ranheimet al.1993)CD80 is a member of the immunoglobulin superfamily having an extracellular domain bearing both a single Ig-v-like domain, a single Ig-c-like domain, a transmembrane sequence and a short cytoplasmic domain. Although the predicted molecular weight for human CD80 is ~33kDa, the presence of multiple (8) potential N-glycosylation sites (Chenet al.1998) results in a migration corresponding to ~60kDa.Human CD80 along with CD86 act as co-stimulatory molecules and are both ligands for CD28 and CTLA-4 (Azumaet al.1993) involved in T cell activation and proliferation (Vasuet al.2003). Although CD80 binds to the same receptors as CD86 it displays quite different characteristics in its avidity and binding kinetics (van der Merwe et al.1997).Site mutagenesis studies indicate residues in both the Ig-v-like and Ig-c-like domains of CD80 are crucial for the interaction with it’s receptors CTLA-4 and CD28 (Peachet al.1995).Mouse anti-human CD80 antibody, clone MEM-233 binds to residues within the Ig-v-like domain of human CD80 as shown by domain switching studies (Vasuet al.2003).Functional studies using Mouse anti-Human CD80, clone MEM-233 in combination with Mouse anti-Human CD86, clone Bu63 suggest that clone MEM-233 is able to block binding of human CD80 with it's cognate ligands CD28 and CTLA-4 (Morbachet al.2011).|
