CD101 Antibody (PA5-143965) in IHC (P)
Immunohistochemistry analysis of CD101 in paraffin-embedded section of human adenocarcinoma of the right colon tissue. Heat mediated antigen retrieval was performed in EDTA buffer (pH 8.0, epitope retrieval solution). The tissue section was blocked with 10% goat serum. Samples were incubated with CD101 Polyclonal antibody (Product # PA5-143965) using a dilution of 2 μg/mL overnight at 4°C. Peroxidase Conjug... View More

Target Information
CD101, also known as the V7 antigen, is a transmembrane glycoprotein and a member of the immunoglobulin superfamily. It is characterized by 7 Ig-like IgV domains and a short cytoplasmic tail with several phosphorylation sites. CD101 forms a disulfide-linked homodimer, although its precise function remains unknown. Expression of CD101 is observed on monocytes, granulocytes, dendritic cells, Langerhans cells, and activated T cells. It is also found on a subset of CD25+Foxp3+ regulatory T cells, which exhibit higher suppressive properties in vitro and in vivo. CD101 plays a role in modulating immune responses. Cross-linking CD101 can antagonize TCR/CD3-mediated lymphocyte activation, while CD101+ CD28+ T cells are highly responsive to CD28 signaling. In combination with anti-CD28 or suboptimal levels of anti-CD3, anti-CD101 can enhance proliferation, suggesting an activating role. The monoclonal antibody BB27 has been shown to inhibit T cell reactivity in allogeneic and antigen-specific mixed DC-T cell cultures. In mice, CD101 is expressed on a subpopulation of regulatory T cells (CD4+, CD25+, Foxp3+) with high suppressor activity. In humans, CD101 expression on peripheral blood mononuclear cells (PBMCs) stains approximately 30% of Foxp3+ cells, although studies have not confirmed higher suppressor activity in the human CD101+ population.
