一般描述

Monoclonal Anti-Human CD4 (mouse IgG1 isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cell line NS-1 and splenocytes from Balb/c mice immunized with CD4-Transfected mouse T-cell hybridoma, 3DT, followed by CD4+ human T-cell CEM cells. Cluster of differentiation 4 (CD4) human cell surface glycoprotein (59kDa) belongs to the immunoglobulin superfamily. It is expressed on the helper/inducer T cell subset, which is found on the majority of peripheral blood neutrophils, most cortical and mature medullary thymocytes, microglial cells, dendritic cells and on some malignancies of T cell origin.

特异性

Recognizes the CD4. The epitope recognized by the Q4120 clone is located on 1-183 aa and is sensitive to formalin fixation and paraffin embedding. 5th Workshop: code no. CD04.11

免疫原

CD4-transfected mouse T-cell hybridoma, 3DT, followed by CD4+ human T-cell CEM cells.

应用

Monoclonal Anti-CD4 antibody produced in mouse has been used in indirect immunofluorescent staining.

生化/生理作用

Cluster of differentiation 4 (CD4) molecule binds to the major histocompatibility complex (MHC) class II molecules during the interaction of CD4+ T cells with antigen presenting cells or with target cells. It also serves as a high affinity cellular receptor for the GP 120 envelope glycoprotein of the human immunodeficiency virus (HIV-1, HIV-2). The CD4 molecule is involved in the adhesion of T-lymphocytes to target cells, thymic development, transmission of intracellular signals during T cell activation, and binding to polyclonal immunoglobulins. Lower levels of CD4 have been detected in monocytes, macrophages and granulocytes.

目标描述

CD4 is a single chain transmembraneous glycoprotein from the immunoglobulin superfamily. It is expressed on the helper/inducer T subset, on most medullary thymocytes, on microglial, dendritic and on some malignancies of T cell origin. The antigen binds to MHC class II molecules and is associated with p56lck protein tyrosine kinase.

外形

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide.

    CXCR4 is a coreceptor, along with CD4, for human immunodeficiency virus type 1 (HIV-1). Trimolecular complexes between HIV-1 glycoprotein (gp)120, CD4 and CXCR4 constitute a prerequisite for HIV entry. We studied whether CD4 is associated with CXCR4 on CD4+ CXCR4+
