Description: The lymphocyte Fcγ receptors recognize the Fc portion of IgG, presented either as immune complexes or as free antibody. The different classes of receptors are distinct because of varying size, tissue distribution and affinity for IgGs. The Fc type II receptor is expressed on a wide variety of cells including B cells, hematopoietic cells, monocyte/macrophages, neutrophils, platelets, Langerhans cells, eosinophils, basophils, trophoblasts, and endothelial cells of the placenta. The Fcγ type III receptors are higher affinity than the type II and are expressed on macrophages, NK cells and neutrophils. Both types of receptors can be expressed on the same cell and in varying ratios. The receptors are constitutively expressed, although cytokines and lymphokines can modulate their expression. Besides identifying FcγR+ cells, monoclonal antibodies to the FcγII/III receptor have been used to block Fc receptor binding of IgG, Fc-mediated signal transduction and effector functions, clearance of immune complexes and to attenuate infection by organisms dependent on FcγR for parasitic invasion. The monoclonal antibody 93 recognizes a conformational epitope formed by FcγII and FcγIII receptors.

Catalog Number: (103259-932)
Supplier: Southern Biotechnology
Description: CD62L, also known as L-selectin, is a type I transmembrane glycoprotein with lectin-like and epidermal growth factor-like domains. It binds to sialylated oligosaccharide determinants on high endothelial venules (HEV) in peripheral lymph nodes. In the mouse, CD62L is expressed on most thymocytes and on peripheral leukocytes, including B and T lymphocytes, neutrophils, monocytes, and eosinophils. This member of the selectin family of cell adhesion molecules appears to be required for lymphocyte homing to peripheral lymph nodes and for leukocyte extravasation at sites of inflammation. Expression of CD62L on lymphocytes and neutrophils is rapidly down-regulated upon cell activation and the level of CD62L expression, along with other markers, distinguishes naive T cells from effector/memory T cells. The monoclonal antibody MEL-14 blocks in vitro binding of lymphocytes to peripheral lymph node HEV and inhibits in vivo lymphocyte extravasation into peripheral lymph nodes and the late stages of leukocyte rolling.


Catalog Number: (100243-566)
Supplier: Southern Biotechnology
Description: The monoclonal antibody 5H10.27 reacts with the α5 chain (VLA-5) of the CD49e/CD29 heterodimeric fibronectin receptor. It is expressed on thymocytes, activated T cells, mast cells, and a variety of mouse cell lines. Soluble 5H10.27 antibody inhibits VLA-5-mediated functions in vitro. Immobilized 5H10.27 has also been demonstrated to costimulate the proliferative response of CD8+ T cells to plate-bound anti-CD3 monoclonal antibody.

Description: Sheep Anti-FITC-HRP for use in ELISA and immunohistochemistry assays.


Catalog Number: (103265-000)
Supplier: Southern Biotechnology
Description: Alexa Fluor 647 Anti-Goat IgG Fc antibody for use in western blotting, immunohistochemistry, and other fluorescent assays.


Catalog Number: (103264-626)
Supplier: Southern Biotechnology
Description: The αβ TCR is expressed on T lymphocytes of all mouse strains tested. The H57-597 monoclonal antibody does not react with γδ TCR-bearing cells. Plate-bound or soluble H57-597 activates αβ TCR-bearing T cells. In vitro and in vivo, H57-597 can induce immature thymocytes to undergo apoptosis. In vivo administration of H57-597 has been shown to deplete αβ TCR-bearing cells to near completion and prevent graft rejection.


Catalog Number: (100244-858)
Supplier: Southern Biotechnology
Description: Porcine CD8, a type I transmembrane glycoprotein, is expressed as either a CD8αα homodimer or a CD8αβ heterodimer. It is found on most thymocytes and on the suppressor/cytotoxic subpopulation of peripheral T cells. CD8 functions primarily as a co-receptor with MHC Class I-restricted T cell receptors in antigen recognition. The monoclonal antibody 76-2-11 reacts with the CD8 α-chain.


Catalog Number: (101442-746)
Supplier: Southern Biotechnology
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.

Catalog Number: (103264-630)
Supplier: Southern Biotechnology
Description: The CD45 antigen is an essential regulator of leukocyte activation and development and is now known to be a protein tyrosine phosphatase, e.g., CD45 is able to dephosphorylate the Src family of protein kinases. This activity is now known to be required for signal transduction induced by T and B cell antigen receptor engagement, cytokine signaling, and Fc receptor stimulation. The functional state of CD45 also has a pronounced effect on lymphocyte development. CD45 exists in multiple forms, such as the restricted variants (CD45R; see companion products 1660, 1665, 1675, 1685, and 1820) and as allelic forms CD45.1 (Ly-5.1) and CD45.2 (Ly-5.2). The former arises as a result of alternative splicing of different exons. The specificity of antibodies to CD45.1 and CD45.2 has been exploited in studies where resolution of donor and recipient cells is essential, such as in gene therapy or bone marrow transplantation. The monoclonal antibody A20 recognizes all mouse leukocytes expressing the CD45.1 allotype.
