Scientific Data Images for Mouse B7-1/CD80 Antibody

B7-1/CD80 antibody in Mouse Colon Tissue by Immunohistochemistry (IHC-P).

B7-1/CD80 in Mouse Colon Tissue.

B7-1/CD80 was detected in immersion fixed paraffin-embedded sections of mouse colon tissue using Rat Anti-Mouse B7-1/CD80 Monoclonal Antibody (Catalog # MAB740) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Rat IgG VisUCyte™ HRP Polymer Antibody (VC005). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to epithelial cells.

B7-1/CD80 antibody in Human Tonsil by Immunohistochemistry (IHC-P).

B7‑1/CD80 in Human Tonsil.

B7-1/CD80 was detected in immersion fixed paraffin-embedded sections of human tonsil using Rat Anti-Mouse B7-1/CD80 Monoclonal Antibody (Catalog # MAB740) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Rat HRP-DAB Cell & Tissue Staining Kit (brown; CTS017) and counterstained with hematoxylin (blue). Specific staining was localized to lymphocyte cytoplasm.

Background: B7-1/CD80

B7-1 and B7-2, together with their receptors CD28 and CTLA-4, constitute one of the dominant costimulatory pathways that regulate T and B cell responses. Although both CTLA-4 and CD28 can bind to the same ligands, CTLA-4 binds to B7-1 and B7-2 with a 20-100 fold higher affinity than CD28 and is involved in the down-regulation of the immune response. B7-1 is expressed on activated B cells, activated T cells, and macrophages. B7-2 is constitutively expressed on interdigitating dendritic cells, Langerhans cells, peripheral blood dendritic cells, memory B cells, and germinal center B cells. Additionally, B7-2 is expressed at low levels on monocytes and can be up-regulated through interferon gamma. B7-1 and B7-2 are both members of the immunoglobulin superfamily. Mouse B7-1 is a 306 amino acid (aa) protein containing a putative 37 aa signal peptide, a 190 aa extracellular domain, a 22 aa transmembrane domain, and a 38 aa cytoplasmic domain. Mouse B7-1 and B7-2 share 28% amino acid identity. Mouse and human B7-1 share 44% amino acid identity. However, it has been observed that both human and mouse B7-1 and B7-2 can bind to either human or mouse CD28 and CTLA-4, suggesting that there are conserved amino acids which form the B7-1/B7-2/CD28/CTLA-4 critical binding sites.
