NB100-64849 recognizes the human CD152 cell surface antigen, also known as CTLA-4 (cytotoxic T-lymphocyte-associated antigen 4). CD152 is a 45kD glycoprotein, expressed normally as a disulphide-linked homodimer. It is expressed transiently on the surface of T cells following activation (peaking at 3 days), but is often present with the cytoplasm. CD152 is a ligand for CD80 and CD86, and is important in cellular interactions during the immune response.

Membrane permeabilization is required for Flow Cytometry. The epitope recognised by this antibody is reported to be sensitive to formaldehyde fixation and tissue processing. The use of acetone fixation for frozen sections is recommended.
ligand and transmembrane spliced cytotoxic T lymphocyte associated antigen 4
CTLA4 has a critical role in T cell differentiation and contributes to the maintenance of peripheral T cell tolerance to self antigens. It exerts its major effects on T cell immune responses via regulation of the cell cycle and may be involved in T cell activation. It binds to B7-1 (CD80) and B7-2 (CD86), and it contains one immunoglobulin-like V type domain. It is widely expressed, with highest levels in lymphoid tissues.

CD86 - I work in tandem with CD80 CD86 belongs to the immunoglobulin superfamily of proteins that drive innate and adaptive immune responses. It is an 80kD co-stimulatory molecule for the priming and activation of naive and memory T-cells, respectively. CD86 is expressed on activated... Read full blog post.
