Supplier:  Southern Biotechnology
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:   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.

Description:   Mouse IgG3-Biotin for use as a control in flow cytometry and immunocytochemistry assays.
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.

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:   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.

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:   Murine CD79 is a disulfide-linked heterodimer composed of an α chain (CD79a) and a β chain (CD79b) that associates non-covalently with membrane immunoglobulin (Ig) to form the B cell receptor (BCR) complex. Its expression is restricted to B lymphocytes first appearing on the surface at the pro-B cell stage prior to productive Ig gene rearrangements and remaining through all stages of B-cell differentiation prior to plasma cells. It has been proposed that the CD79 complex on pro-B cell surfaces may function to induce early B-cell differentiation.

Description:   CD43, a member of the sialomucin family of cell surface receptors, is a 95-135 kDa type I transmembrane glycoprotein whose variability in molecular weight is dependent upon the nature of the extracellular O-glycans. It is the major sialoglycoprotein on thymocytes, T cells, and neutrophils. It is also present on activated B cells, plasma cells, NK cells, granulocytes, monocytes, macrophages, platelets, and bone marrow hematopoietic stem cells. CD43, which binds to ICAM-1 (CD54), appears to function as an anti-adhesion molecule, inhibiting T cell interactions including T cell killing, and by increasing the threshold for T cell activation.
