General description

CD4, a glycoprotein, is predominantly expressed on the cell membrane of mature, thymus-derived (T) lymphocyte and also to some extent in the monocyte/macrophage lineage. It has a transmembrane domain, cytoplasmic region and an extracellular region of four tandem domain similar to members of Ig (immunoglobin) superfamily.

Immunogen

T-cell surface glycoprotein CD4 precursor recombinant protein epitope signature tag (PrEST)

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

CD4 (cluster of differentiation 4) interacts with the CD4+ T cells with antigen-presenting cells or with target cells by binding to the major histocompatibility complex (MHC) class II molecules. Interaction with MHC-II molecules increases the cytokine expression and the differentiation of human monocytes into functional mature macrophages. Further, it effects human immunodeficiency virus (HIV) binding and subsequent infection. Thus, it proves an important role in HIV as the primary receptor.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
