Supplier: Southern Biotechnology
Description: CD24, also known as heat stable antigen, is a phosphatidylinositol-linked cell surface glycoprotein that is expressed at all stages of B cell development and on most thymocytes. The absence of expression from mature T cells is closely associated with their maturation from CD4+CD8+CD24+ thymocytes to either CD4+CD8-CD24- or CD4-CD8+CD24- T cells. CD24 is also present on mouse granulocytes, monocytes, Langerhans cells and erythrocytes. Its ligand is P-selectin (CD62P). CD24 may play a role in regulation of B cell proliferation and differentiation, and it has been proposed that heat stable antigen promotes homotypic adhesion between B lymphocytes.

Description: Porcine CD4 is a type I transmembrane glycoprotein and a member of the immunoglobulin superfamily of cell surface receptors. CD4 is an accessory molecule in the recognition of foreign antigens in association with MHC Class II molecules by T lymphocytes.


Catalog Number: (103264-528)
Supplier: Southern Biotechnology
Description: CD3ε, a member of the immunoglobulin superfamily of cell surface receptors, is comprised of five invariable chains ranging in size from 16-28 kDa and is closely associated with the T cell antigen receptor (TCR). It is expressed on all T cells of all mouse strains. CD3 plays a major role in signaling during antigen recognition, leading to T-cell activation. The 145-2C11 monoclonal antibody recognizes an epitope on the 25 kDa ε chain of the CD3/TCR complex. In the presence of Fc receptor-bearing accessory cells, soluble 145-2C11 can activate primed and naïve T cell in vitro. 145-2C11 can also induce redirected lysis of specific target cells by CTL clones and it can block lysis of specific target cells by antigen-specific CTL’s. Immobilized 145-2C11 can activate both normal T lymphocytes and cloned T cell lines. Under certain conditions, T cell activation by 145-2C11 may result in apoptotic cell death.


Catalog Number: (103260-194)
Supplier: Southern Biotechnology
Description: CD4 is a 55 kDa type I transmembrane glycoprotein and a member of the Ig-SF of cell surface receptors. It is expressed predominantly on the “helper/inducer” subpopulation of mature T lymphocytes and on monocytes and macrophages. Domains 1 and 2 bind to MHC Class II antigens, while domains 3 and 4 may be involved in cis interactions with the CD3/TCR complex. CD4 functions as an accessory molecule in the recognition of foreign antigens in association with MHC class II antigens by T cells.


Catalog Number: (101442-770)
Supplier: Southern Biotechnology
Description: CD45R, also known as B220, a member of the protein tyrosine phosphate family and a major cell surface glycoprotein, represents a restricted form of the CD45 family which primarily recognizes only cells of B-lineage from pro-B cell through mature B lymphocytes and prior to the availability of anti-CD19 monoclonal antibodies was commonly used as a pan B-cell marker. It also reacts with certain activated T cells as well as non-MHC-restricted lytically active lymphokine-activated killer (LAK) cells. In vivo administration of RA3-6B2 has been shown to affect differentiation of both T and B cells in normal mice and reduce the level of anti-DNA antibodies and lymphadenopathies in MRL/lpr mice.


Catalog Number: (100244-948)
Supplier: Southern Biotechnology
Description: Rabbit F(ab')2 Anti-Goat IgG(H+L)-HRP antibody for use in ELISA, immunohistochemistry / immunocytochemistry, and western blotting assays.


Catalog Number: (100243-404)
Supplier: Southern Biotechnology
Description: CD30 is a type I transmembrane protein and a member of the tumor necrosis factor receptor superfamily of proteins. Murine CD30 is expressed predominantly in the thymus and it is inducible in mouse splenocytes stimulated with pokeweed mitogen or concanavalin A. In anti-CD3ε-activated spleen cells, CD30 is expressed primarily on the surface of CD8+ T cells with peak expression on days 4 and 5. Stimulation of CD30+ CTL lines with plate-bound anti-CD30 directly signals IL-5 but not IFN-γ production. While these studies demonstrate that CD30 directs cytokine secretion and suggest that CD30 may play a pivotal role in the pattern of cytokine production by T cells, the precise roles of CD30 and its ligand (CD153) in T-cell development have not been clearly defined.


Catalog Number: (100245-580)
Supplier: Southern Biotechnology
Description: Chicken Bu-1b, a product of the Bu-1b allele, is expressed on the cell surface as a disulfide-linked homodimer. In 10-week-old H.B15 and H.B2 chickens, Bu-1 is found on 85-90% of bursal cells, 2-8% of thymocytes, 15-27% of spleen cells, and 2-18% of peripheral blood cells. It is also expressed on subsets of macrophages and monocytes but not on granulocytes, erythrocytes, or thrombocytes. In chickens heterozygous for the Bu-1 alleles (Bu-1a/b), Bu-1a does not exhibit allelic exclusion. The monoclonal antibody 5-11G2 reacts with lymphoid cells from CHA and H.B14Ab strains but does not react with cells from H.B14Aa
