Description: The 15.2 antibody reacts with the 85-110 kDa intracellular adhesion molecule-1 (ICAM-1), a member of the Ig superfamily which acts as a ligand for the Lymphocyte Function-Associated Antigen-1 (LFA-1). ICAM-1 is also known CD 54 and is expressed on non-hematopoietic cells of vascular endothelial, thymic epithelial, fibroblasts lineages, and on hematopoietic cells like macrophages, mitogen-stimulated T-lymphoblasts, dendritic cells in tonsils, lymph nodes and Peyer’s patches, and germinal center B cells.Inflammatory mediators (IL-1, TNF, IFN-γ) enhance the production of ICAM-1 on fibroblasts and endothelial cells within few hours. Thus, ICAM-1 seems to be the marker of inflammatory reactions.

Description: The RPA-T4 monoclonal antibody specifically binds to the CD4 receptor for the human immunodeficiency virus (HIV). CD4 is a 59 kDa single-chain transmembrane glycoprotein that expressed on the surface of most of the thymocytes, T-helper cells, and in low levels on monocytes and macrophages. CD4 is a co-receptor in the antigen-induced T cell activation, together with the MHC class II. The RPA-T4 antibody is capable of blocking HIV binding and inhibiting syncytium formation, by binding to the D1 domain of the CD4 antigen. The OKT4 and the RPA-T4 monoclonal antibodies recognize different epitopes of CD4 and they do not exhibit cross-block binding.

Description: The RM4-5 monoclonal antibody specifically reacts with mouse CD4, also known as L3T4, a 55 kDa differentiation antigen expressed by the majority of thymocytes, subpopulations of mature T cells (like major histocompatibility complex class II-restricted T lymphocytes), a subset of natural killer T cells, and on pluripotent hematopoietic stem cells. CD4 binds to the major histocompatibility complex class II (MHC class II) and enhances T lymphocyte development and mature T cells functions. In T lymphocytes, CD4 binds to the cytoplasmic tail of enzyme tyrosine kinase (p56lck).Binding of RM4-5 is blocked by the anti-mouse CD4 clone GK1.5.

Description: The GL-1 monoclonal antibody reacts specifically with the mouse B7-2 (also known as CD86), a costimulatory molecule expressed by B and T lymphocytes, macrophages (thioglycollate-induced from peritoneum), astrocytes and dendritic cells. The memory CD4+ T lymphocytes express CD86 (as mRNA and protein). CD86, and the B7-1 (CD 80) molecule, are ligands for CD152 and CD28, and influence the costimulatory interactions between lymphocytes B and T. B7-2 is also involved in the mouse natural killer cell-mediated cytotoxicity. The GL-1 antibody blocks the mixed lymphocyte reaction (MLR) and inhibits the T-cells stimulation by antigen-presenting cells. Mixtures of anti-B7-1 antibody and GL-1 were reported to inhibit the interaction between CD125 and its ligand with the in vivo priming of cytotoxic T lymphocytes.

Description: The RPA-T8 monoclonal antibody specifically reacts with the human CD8a molecule, a 32 kDa cell surface receptor expressed either as a heterodimer (CD8 α/β) or as a homodimer (CD8 α/α) on the majority of thymocytes, a subpopulation of mature T cells, and natural killer cells. CD8 interacts with the major histocompatibility complex class I (MHC class I) molecules on antigen-presenting cells or epithelial cells. The RPA-T8 antibody reacts with 13-48% of peripheral lymphocytes, 80% of thymocytes, and a subset of natural killer cells. RPA-T8, OKT8, and HIT8a antibodies do not compete with each other for binding to peripheral leukocytes, meaning that that they do not recognize the same epitope or block each other by steric hindrance.
