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: CD107b, also known as lysosomal-associated membrane protein 2 (LAMP-2), is a heavily glycosylated type I transmembrane protein that constitutes the major sialoglycoproteins on lysosomal membranes. It is a ligand for galaptin, an S-type lectin present in extracellular matrix, through its recognition of acetyllactosamine oligosaccharide chains and is a ligand for E-selectin-mediated cell adhesion. CD107b is expressed in lysosomal/endosomal membranes and on the surface of activated platelets and some tumor cell lines including U937 and KG1a. LAMP-2 may function in protecting the inner surface of the lysosomal membrane by forming a barrier to lysosomal hydrolases. The upregulation of both CD107a and CD107b on the surface of tumor cell lines has been associated with their enhanced metastatic potential where they may increase adhesion to extracellular matrix and endothelium.

Description: Chicken CD44 is a type I transmembrane glycoprotein expressed on many cell types including B cells, most T cells, monocytes, and some epithelial cells. CD44 primarily functions as an adhesion molecule. It has been implicated in various processes such as hematopoiesis, lymphocyte homing, leukocyte activation, tumor metastasis, and development. The monoclonal antibody AV6 also reacts with turkey peripheral blood mononuclear cells.


Catalog Number: (101442-750)
Supplier: Southern Biotechnology
Description: The CD23 antigen is the low affinity IgE Fc receptor, which is a 45-49 kDa protein with 38 and 28 kDa fragments. It is expressed on most mature, conventional B cells (but not on peritoneal CD5+ B cells) and can also be found on the surface of T cells, macrophages and platelets. It is distinct from the high affinity IgE receptors found on basophils and mast cells which mediate allergic reactions. The low affinity receptors are thought to play a role in isotype specific immunoregulation. The regulation of CD23 surface expression appears to be integral with the complex IgE system which involves interactions of cells, cytokines, antibodies and regulatory factors. CD23 has been described as a “membrane bound cytokine," in that the soluble cleavage products of CD23 are themselves able to act as cytokines in vitro.


Catalog Number: (103259-812)
Supplier: Southern Biotechnology
Description: Goat Anti-Mouse IgG2b-HRP antibody for use in ELISA assays.


Catalog Number: (100245-930)
Supplier: Southern Biotechnology
Description: CD20 is a 33-37 kDa unglycosylated phosphoprotein. Although not a member of the tetraspanin superfamily of cell surface receptors, it crosses the cell membrane four times. It is expressed on all stages of B cell differentiation except plasma cells. The CD20 molecule is involved in regulation of B cell differentiation presumably via its reported function as a Ca++ channel subunit.


Catalog Number: (100242-228)
Supplier: Southern Biotechnology
Description: Bcl-xL is a 29 kDa member of the Bcl-2 family of proteins involved in regulation of programmed cell death, or apoptosis. It is found in both soluble and membrane fractions of cellular lysates. Like Bcl-2, Bcl-xL has been demonstrated to block apoptosis which is induced by a variety of stimuli and, under certain conditions, offers greater protection against apoptosis than Bcl-2. While formation of heterodimers with the apoptosis-enhancing protein, Bax does not block the apoptosis-suppressing property of Bcl-xL, heterodimerization with Bad effectively inhibits the protective function of Bcl-xL.


Catalog Number: (100243-624)
Supplier: Southern Biotechnology
Description: CD71, a type II transmembrane glycoprotein expressed on the cell surface as a homodimer, is the transferrin receptor. It is essential for the growth of normal and neoplastic cells. It is expressed at low levels on resting B and T lymphocytes but is upregulated during responses to antigens and mitogens presumably reflecting the iron dependence of proliferation. Its expression declines with maturation and differentiation. CD71 plays a critical role in cell proliferation by controlling the supply of iron which is essential for many metabolic pathways through the binding and endocytosis of transferrin, the major iron-carrying protein. It may also be involved in signal transduction via its association with the T cell receptor ζ chain. The monoclonal antibody RI7217 inhibits cell proliferation in vitro.

Supplier: Southern Biotechnology
Description: Goat Anti-Rabbit IgG(H+L)-FITC antibody with minimal reactivity to mouse and human proteins for use in flow cytometry, immunohistochemistry / immunocytochemistry, and western blotting assays.


Catalog Number: (100243-246)
Supplier: Southern Biotechnology
Description: CD11b, the integrin αM subunit, combines with CD18, the integrin β2 subunit, to form the integrin Mac-1, also known as complement receptor 3 (CR3), which mediates adhesion to C3bi and ICAM-1/CD54. Mac-1 is expressed at varying levels on granulocytes, macrophages, dendritic cells, NK cells, and B-1 cells in the peritoneal and pleural cavities. Mac-1 expression is rapidly up-regulated on neutrophils after activation and in the same time period that CD62L is shed from the cell surface. In addition to its role in binding C3bi on opsonized targets and mediation of the subsequent ingestion process, Mac-1 is important as an adhesion molecule in the transendothelial migration of monocytes and neutrophils. Cross-reaction of M1/70 to human CD11b has been observed on monocytes, polymorphonuclear leukocytes, and NK cells.
