Description: CD95, also known as Fas and APO-1, is a 45 kDa type I transmembrane glycoprotein and a member of the tumor necrosis factor receptor superfamily. It is expressed by activated lymphocytes, monocytes, neutrophils, fibroblasts, and cell lines. Fas ligand binding to CD95 induces apoptosis in activated mature lymphocytes thereby playing a role in maintaining peripheral tolerance. Crosslinking of CD95 by the monoclonal antibodies DX2 and DX3 delivers an apoptotic signal to Fas-sensitive cells indicating that these monoclonal antibodies recognize a functional epitope of CD95.

Description: CD86, also known as B7-2, is a type I transmembrane glycoprotein and a member of the immunoglobulin superfamily of cell surface receptors. It is expressed at high levels on resting peripheral monocytes and dendritic cells and at very low density on resting B and T lymphocytes. CD86 expression is rapidly upregulated by B-cell specific stimuli with peak expression at 18-42 hours after stimulation. CD86, along with CD80 (B7-1), is an important accessory molecule in T cell costimulation via its interaction with CD28 and CD152 (CTLA-4). Since CD86 has rapid kinetics of induction, it is believed to be the major CD28 ligand expressed early in the immune response. The monoclonal antibody GL1 blocks mixed lymphocyte reactions and stimulation of T cells by antigen-presenting cells.

Description: CD1 molecules, like MHC I and II, play an important role in the immune system by presenting lipid, glycolipid and lipopeptide antigen to T and NKT cells. The chicken CD1 gene is located in the chicken MHC B locus and has an important implication for the primordial MHC gene evolution. Two proteins have been identified - CD1.1 and CD1.2. Analysis of RNA from blood cells showed that both genes are expressed in Bu-1+ cells and CD8α+ cells. CD1.2 is expressed in TCRγδ cells but is nearly undetectable in TCRαβ. The monoclonal antibody CB3 antibody can identify cells of the B cell lineage and recognizes CD1.1 but not CD1.2 on the surface of transfected mammalian cells.

Description: Chicken MCAM, a member of the immunoglobulin superfamily of cell surface receptors, consists of the V-V-C2-C2-C2 Ig domains. It is a single chain glycoprotein with three mRNA splice variants. One has a short cytoplasmic tail, another has a long tail, and the third seems to lack transmembrane and cytoplasmic regions. It is highly homologous to gicerin, a molecule involved in neurite outgrowth and Wilm’s kidney tumor progression in the chicken, and to the human melanoma progression molecule MUC18. Chicken MCAM is expressed by c-kit+ hematopoietic progenitor cells in embryonic bone marrow, thymocytes, and capillary endothelial cells. MCAM-expressing cells sorted from bone marrow are enriched in progenitors capable of differentiating into T cells when transferred into the appropriate thymic microenvironment. MCAM has been proposed to be involved in cellular adhesion and homing processes.

Description: CD11a, also known as leukocyte function-associated antigen-1 (LFA-1α), represents the 180 kDa integrin αL subunit which combines with the CD18 β2 integrin subunit to form the αLβ2 integrin heterodimer. It is expressed on lymphocytes, granulocytes, monocytes, and macrophages and is upregulated on activated T cells. CD11a mediates adhesion of lymphocytes to vascular endothelium and is involved in costimulation.

Description: CD14 is a 55 kDa glycosphosphatidylinositol (GPI)-anchored single chain glycoprotein. It is expressed on monocytes, macrophages, dendritic cells, and Langerhans cells. It is also weakly expressed on neutrophils. CD14 appears to be involved in clearance of gram-negative bacteria via its high affinity binding to LPS-LPB complexes.

Description: Keratins are a family of intermediate filament proteins that assemble into filaments through forming heterodimers of one type I keratin (keratins 9 to 23) and one type II keratin (keratins 1-8). The two keratin types share only 30% sequence homology. Keratins demonstrate tissue- and differentiation-specific expression profiles. Cytokeratin 8 belongs to the type B (basic) subfamily of keratins and exists in combination with keratin 18. It is expressed in all simple type epithelia tissues (e.g., liver, pancreas, kidney, gut epithelial lining) but not in stratified squamous epithelia. Cytokeratin 8 is also present in the majority of adenocarcinomas and ductal carcinomas but is absent in most squamous cell carcinomas.

Description: The IL-2 receptor (IL-2R) exists in three alternative forms made up from the individual components of CD25, CD122, and CD132. CD25 represents the low affinity α chain of the IL-2R, a type I transmembrane glycoprotein containing two CCP domains. It is rich in O-linked carbohydrates and has a short cytoplasmic tail. CD25 is expressed on activated T cells, B cells, NK cells, and monocytes of all mouse strains tested. It is transiently expressed at a low level during B cell development in bone marrow on the CD45R/B220low TdT- sIg- pre-B II and CD45R/B220low TdT- sIgM+sIgD- immature B cells, but not on the CD45R/B220low TdT+ sIg- pro-B/pre-B I stage nor on CD45R/B220high TdT- sIgM+sIgD+ mature B cells. CD25 is expressed at a higher level during very early T-cell development in fetal and adult thymus. The 7D4 monoclonal antibody reacts with an epitope between amino acids 125 and 212 that is distinct from that recognized by the monoclonal antibody 3C7 (SB Cat. No. 1600). While the monoclonal antibody 7D4 does not block the binding of IL-2 to CD25, when used in combination with the monoclonal antibody 3C7 it results in higher levels of inhibition of IL-2-driven proliferation than either of these two monoclonal antibodies alone.

Description: CD42b, also known as GPIbα, is a two-chain membrane glycoprotein that forms a noncovalent complex with CD42a (GPIX) on the surface of platelets and megakaryocytes. Binding of the GPIb/GPIX heterodimer to von Willebrand factor bound to exposed subendothelial surfaces is essential for platelet adhesion at sites of injury.

Description: Porcine CD8, a type I transmembrane glycoprotein, is expressed as either a CD8αα homodimer or a CD8αβ heterodimer. It is found on most thymocytes and on the suppressor/cytotoxic subpopulation of peripheral T cells. CD8 functions primarily as a co-receptor with MHC Class I-restricted T cell receptors in antigen recognition. The monoclonal antibody 76-2-11 reacts with the CD8 α-chain.
