Description: CD86 (B7-2) is an 80 kDa type I integral membrane protein and a member of the immunoglobulin superfamily of cell surface receptors. Along with CD80 (B7-1), CD86 participates in T cell costimulation via interaction with CD28 and CD152 (CTLA-4). It is expressed at very low density in normal tissues but is rapidly upregulated on stimulated B cells, monocytes, and dendritic cells. Since CD86 has rapid kinetics of induction, it is believed to be the major CD28 ligand expressed early in the immune response.

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.

Supplier: Southern Biotechnology
Description: CD45, also known as the leukocyte common antigen (LCA), exists as four different isoforms (180, 190, 205, 220 kDa) that are generated by alternative splicing of three exons. LCA is found on all cells of hematopoietic origin, except erythrocytes and platelets. CD45 expression is required for T cell and B cell antigen receptor-mediated activation.

Description: The monoclonal antibody DX5 reacts with CD49b, also known as very late antigen-2 (VLA-2) and α2 integrin. The antibody stains the majority of NK cells and a small subpopulation of T cells in all mouse strains tested (e.g., A/J, AKR, BALB/c, C3H/HeJ, C57BL/6, C57BL/10, C57BR, C58, CBA/Ca, CBA/J, DBA/1, DBA/2, SJL, SWR). Three-color flow cytometry analysis has revealed that most cells that express NK-1.1 (NKR-P1C) also express CD49b. However, small subsets of DX5+NK-1.1- and DX5-NK-1.1+ cells can be found, especially among the CD3+ population of T lymphocytes. NK cells cultured in the presence of IL-2 progressively lose reactivity with DX5 as a consequence of cellular proliferation. Therefore, DX5 can be used to define functionally distinct subsets of murine NK cells. The monoclonal antibody DX5 has not been demonstrated to have activating or blocking activity.

Description: CD19 is a monomeric transmembrane glycoprotein expressed at relatively constant levels throughout B cell development from early pro-B/pre-B cells (i.e. B220+/CD43+/HSA+) through fully differentiated B cell stages. Terminally differentiated plasma cells do not express CD19. In humans, the CD19 molecule on the surface of mature B cells associates with CD21 (CR-2) and CD81 (TAPA-1), and this multimolecular complex synergizes with surface immunoglobulin to provide signal transduction and promote cellular activation. All splenic and peritoneal IgM+ cells of both B-1 and B-2 lineages are CD19+, with B-1 cells expressing higher levels of CD19 than B-2 cells in these sites. Studies with CD19-deficient mice have suggested that this molecule may not be required for normal generation and maturation of B cells in the bone marrow. The monoclonal antibody 6D5 recognizes the same epitope as the published clone, 1D3.

Catalog Number: (100242-244)
Supplier: Southern Biotechnology
Description: ApoScreen® Annexin V (SB Cat. No. 10040) is a recombinant protein that is expressed in E. coli. A number of changes in cell structure occur during apoptosis. One major change is the loss of membrane phospholipid asymmetry, with translocation of phosphatidylserine (PS) from the inner leaflet of the phospholipid bilayer to the external surface. Annexin V, a member of the annexin family of calcium-dependent phospholipid binding proteins, has a high affinity for phosphatidylserine (PS)-containing phospholipid bilayers. Conjugated Annexin V can be used to monitor changes in cell membrane phospholipid asymmetry, thereby providing a convenient tool for detection of apoptotic cells.

Description: The monoclonal antibody 36-7-5 reacts with the H-2Kk MHC class I alloantigen. Cross-reactivity with splenocytes of SJL/Hsd mice has been observed by flow cytometry. The antibody does not react with other (e.g., b, d, q) haplotypes.


Catalog Number: (100243-328)
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.

Supplier: Southern Biotechnology
Description: The CD35 antigen is composed of four different allotypes having different molecular weights [A (or F) - 160 kDa, B (or S) - 190 kDa, C - 220 kDa, and D - 250 kDa]. It is the receptor for C3b and is found on B cells, a subset of T cells, monocytes, neutrophils, follicular dendritic cells, erythrocytes, and kidney glomelular podocytes. CD35 mediates neutrophil and monocyte phagocytosis of particles coated with C3b and/or C4b. This interaction also enhances phagocytosis mediated by the Fc receptors.


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.
