- Description
- Description: The monoclonal antibody BB27 reacts to human CD101 also known as V7 antigen, a member of the Ig superfamily. CD101 is a disulfide linked homodimer of unknown function. Expression of CD101 is found on monocytes, granulocytes and dendritic cells (Langerhan-like cells HLA-DR, CD1a, CD1c). In addition expression on T lymphocytes is important for cell activation. CD101+ CD28+ cells are very responsive to CD28 signaling. In combination with anti-CD28 or suboptimal levels of anti-CD3, anti-CD101 can increase proliferation thereby suggesting an activating role. The monoclonal antibody BB27 has been shown to inhibit the T cell reactivity in allogeneic and antigen-specific mixed DC-T cell cultures. Recently it has been demonstrated that mouse CD101 is found on a subpopulation of regulatory T cells (CD4, CD25, Foxp3 positive) that have high suppressor activity. Expression of CD101 on human PBMCs shows staining of about 30% of the Foxp3 positive cells. Studies have not confirmed higher suppressor activity in the human CD101 population.

- Staining of normal human peripheral blood cells with Anti-Human CD4 FITC (Product # 11-0048-42) and 0.25 µg of Mouse IgG1 kappa Isotype Control Biotin (Product # 13-4714-85) (left) or 0.25 µg of Anti-Human CD101 Biotin (right) followed by Streptavidin PE (Product # 12-4317-87). Cells in the lymphocyte gate were used for analysis.
