Description: The A20 monoclonal antibody reacts with the leukocytes of the CD45.1-expressing mouse strains (DA, SJL/J, RIII, and STS/A). It does not cross-react with cells that express CD45.2. The CD45 molecule is a member of the Protein Tyrosine Phosphatase (PTP) family, because its intracellular region contains two PTP domains. The extracellular region’s variability is caused by different levels of glycosylation, and the splicing of the 4, 5, and 6 exons. The isoforms found in the mouse strains depend on the activation state, maturation stage and cell type, and are very important in B and T lymphocytes antigen receptor signal transduction. The A20 antibody inhibits some of the B lymphocytes responses, from CD45.1-expressing mice, to lipopolysaccharides and antigens.

Description: The BM8.1 monoclonal antibody specifically binds to the Mouse125 kDa F4/80 antigen, expressed by most mature macrophages. F4/80 is a transmembrane protein used as a marker of macrophages, although it is also expressed on Kupffer and Langerhans cells. The expression of F4/80 antigen is upregulated on bone marrow cells stimulated in vitro with the macrophage colony stimulating factor. The F4/80 antigen is a requirement for the induction of CD8 T cells-mediated peripheral tolerance.

Description: The 10F.9G2 monoclonal antibody specifically reacts with mouse CD274, also known as B7-H1 or PD-L1, a 43 kDa glycoprotein of the B7 family of the immunoglobulin superfamily. CD274 is expressed on the B and T lymphocytes, natural killer cells, and dendritic cells. The receptor for the B7-H1 molecule is PD-1, which contains an Immunoreceptor Tyrosine-based Inhibitory Motif (ITIM), and is expressed on activated B and T cells. The interaction between CD274 and PD-1 seems to downregulate the T and B immune responses.

Description: The BC96 monoclonal antibody specifically reacts with the 55 kDa type I transmembrane glycoprotein known as the interleukin-2 receptor α (IL-2R α, also known as CD25). CD25 is expressed by the early progenitors of T and B lymphocytes lineage, and by activated mature T and B lymphocytes. CD25 is a low affinity interleukin-2 receptor, but its association with the IL-2 receptor β chain (CD122) and the common γ chain (CD 132) results in a high affinity IL-2R complex. CD25 plays an important role in B and T cell proliferation, differentiation, and activation.

Description: The HP-3G10 monoclonal antibody specifically binds to an 80 kDa homodimer type II membrane glycoprotein from the C-type lectin superfamily, known as the human CD161 or NKR-P1A. CD161 is expressed on most natural killer cells, subsets of CD4+ and CD8+ T lymphocytes, γδ TCR T lymphocytes, a subset of CD3+ thymocytes, and especially on CD45RO+ T lymphocytes. Reports indicate that it may serve as a specific receptor for some natural killer cell targets and a possible stimulatory role.

Description: The RA3-6B2 monoclonal antibody specifically reacts with a 220 kDa exon A-restricted epitope on the extracellular domain of mouse CD45 glycoprotein. CD45R/B220 is expressed on all the development stages of B cells, and at a low level on plasma cells and a subset of memory B cells. Low levels of CD45R/B220 are also expressed by some activated T lymphocytes, natural killer cell progenitors in the bone marrow, lymphokine activated killer cells (LAK), T lymphocytes of lpr/lpr mutant mouse, apoptotic T cells of mice injected with bacterial superantigens, and macrophage progenitors in fetal liver.The CD45 molecule is a member of the Protein Tyrosine Phosphatase (PTP) family, because its intracellular region contains two PTP domains. The extracellular region’s variability is caused by different levels of glycosylation, and the splicing of the 4, 5, and 6 exons. The isoforms found in the mouse strains depend on the activation state, maturation stage and cell type, and are very important in B and T lymphocytes antigen receptor signal transduction.The RA3-6B2 antibody inhibits in vivo B lymphocytes responses and enhances isotype switching during in vitro B lymphocyte responses.

Description: The GK1.5 monoclonal antibody specifically binds with the mouse CD4 molecule, also known as L3T4, a 55 kDa differentiation antigen which binds to the MHC class II. CD4 is expressed on most thymocytes, a subpopulation of mature T lymphocytes, dendritic cells, pluripotent hematopoietic stem cells, B cell precursors, and lymphoid precursors inside the thymus. It is also expressed on the mouse egg cell membrane, enhancing adhesion to MHC class II bearing sperm. By interaction with MHC class II on the surface of APC, CD4 initiates the development of T lymphocytes and helps the optimum functioning of mature T lymphocytes. The binding of the GK1.5 antibody blocks the binding of the Anti-Mouse CD4 RM4-5 antibody.

It is produced by T helper 17 (Th17) cells, a unique subset of IL-23 dependent CD4+ T cells. Interleukin-17A is highly expressed in transplant rejection, asthma, psoriasis, and multiple sclerosis, and enhances the expression of ICAM-1 in human fibroblasts. The homodimer is expressed by activated peripheral CD4+ T lymphocytes. The Interleukin-17A binds to the IL-17 receptors (IL-17R) expressed by mast cells, monocytes and macrophages, fibroblasts, and endothelial and epithelial cells.

Description: The PK136 monoclonal antibody is specific for the mouse NK1.1, a receptor from the killer cell lectin-like receptor (KLR) family. Nk1.1 is an antigen encoded by the Klrb1c/NKR-P1C gene expressed by the natural killer cells of some selected strains of mice (C57BL, FVB/N, NZB) and encoded by the Klrb1b/NKR-P1B gene expressed on Swiss NIH and SJL mice. Pk136 binds to an epitope common to NKR-P1B and NKR-P1C.The Klrb1 is a family of type II transmembrane C-type lectin receptors. Klrb1c activates the NK-cell cytotoxicity, while Klrb1b inhibits it. PK136 is useful in defining the NK cells and the rare population of NK-T lymphocytes and specific cultured monocytes.

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.
