一般說明
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.
特異性
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.
應用
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.
標靶描述
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.

We have previously shown that binding of human immunodeficiency virus type 1 (HIV-1) virions to CD4 receptors stimulates association of Lck with Raf-1 and results in the activation of Raf-1 kinase in a Ras-independent manner. In the present study, we
