Attributs du produit: The 1G10 antibody reacts with CD80 (B7-1). This member of the Ig superfamily, along with CD86 (B7-2), participates in T-cell costimulation via interactions with CD28 and CD152 (CTLA-4). CD80 is constitutively expressed on dendritic cells, monocytes, and peritoneal macrophages, and it is inducible on B cells by various means, including activation by LPS, IL-4, and the cross-linking of surface Ig. Expression of CD80 is greatly enhanced on splenic B cells following activation by LPS, with peak expression occurring between 48 and 72 hours. It has been reported that activation of purified B cells with LPS can induce CD80 expression in as few as 18 hours. The 1G10 antibody blocks binding of CTLA-4-Ig to CD80, but it does not block stimulation of T cells by natural antigen-presenting cells. Preliminary evidence has shown that mAb 16-10A1 (Cat. no. 553766) blocks binding of 1G10 mAb to CD80, indicating that the two antibodies may recognize overlapping epitopes on the CD80 Molecule. However, the 16-10A1 mAb recognizes an upregulated antigen on UV-irradiated P815 mastocytoma cells which is not detected by the 1G10 mAb, the cause and significance of this differential reactivity of the two anti-CD80 antibodies is unknown. Expression of membrane CD80 (B7-1) by mouse splenocytes. Freshly isolated (left) or 72-hour LPS-stimulated BALB/c splenocytes (right) were stained with purified 1G10/B7 mAb (open histograms) or no primary mAb (shaded histograms). Staining was detected with biotinylated goat anti-rat Ig (Cat. No. 554014) followed by Streptavidin-PE (Cat. No. 554061). Viable resting lymphocytes (left) and blasts (right) were selected by scatter profile and dye exclusion (BD Pharmingen™ Via-Probe™, Cat. No. 555816/555815). Flow cytometry was performed on a FACScan™ .
