Description: CD3 is a member of the T cell receptor-associated CD3 complex. The monoclonal antibody CT-3 recognizes a complex of at least three polypeptides of Mr 20, 19, and 17 kDa (two of which are N-glycosylated) on chicken T cells. The antibody also coprecipitates a polypeptide of 90 kDa from digitonin solubilized T cell lysates, which can be reduced to two polypeptides of Mr 50 and 40 kDa.

Description: The monoclonal antibody KUL01 is useful in the study of the development, distribution, function, and ontogeny of the mononuclear phagocyte system (MPS) of the chicken by exclusively recognizing the cells of the MPS. It identifies chicken monocytes and macrophages as well as interdigitating cells and activated microglia cells. This antibody does not react with B (Bu-1+) or T (CD3+) lymphocytes.

Description: In the chicken, the CD8 molecule is present in two forms - (i) a homodimer of two α chains and (ii) a heterodimer of an α chain and a β chain. While the vast majority of CD8+ cells in the thymus, spleen, and blood of adult chickens express both CD8α- and CD8β-chains, a relatively large proportion of the CD8+ TCRγδ cells in the spleens of embryos and young chicks express only the α-chain of CD8. Among intestinal epithelial lymphocytes, the major CD8+ T cell populations present in mice are conserved but there is a population of TCRγδ CD8αβ cells in the chicken that is not found in rodents. Chicken CD8 is expressed on approximately 80% of thymocytes, 15% of blood mononuclear cells, and 50% of spleen cells but less than 1% of cells in the bursa and bone marrow. The monoclonal antibody CT-8 recognizes the CD8α chain and has been shown to react to a polymorphic determinant in turkey.

Description: CD5, a member of the scavenger receptor superfamily of cell surface receptors, is a type I transmembrane glycoprotein whose ligand is CD72. It is expressed on most thymocytes, all mature T cells, and a subset of B cells. CD5 plays a role in regulation of T cell activation and signaling.

Description: CD15 is a carbohydrate antigen found on the cell surface of neutrophils and monocytes, but not on basophils, platelets, lymphocytes, or erythrocytes. CD15 may function in adhesion as its ligand is L-selectin (CD62L).

Catalog Number: (103265-468)

Supplier: Southern Biotechnology

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 18 is a type I intermediate filament protein that exists as a heterotetramer composed of two type I and two type II keratins. Cytokeratin 18 is expressed in all simple type epithelia and basal cells of many squamous and non-epidermal epithelia and is often co-expressed with cytokeratin 8. Tissues from the gastrointestinal tract, respiratory tract, and urogenital tract as well as endocrine and exocrine tissues and mesothelial cells are positive for cytokeratin 18.

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 19 is the smallest human keratin. It is found in many simple and some non-keratinizing stratified squamous epithelia and is often co-expressed with keratin 7. Cytokeratin 19 has been implicated as a marker for stem cells in some tissues such as hair follicles in the skin. Monoclonal antibodies to cytokeratin proteins can be useful markers for tumor identification and classification. The degree of cytokeratin 19 positivity in breast cancer distinguishes malignant from benign tumors. Cytokeratin 19 is also associated with malignant transformation in esophageal and pancreatic cancers.
