Immunogen
KLH-conjugated linear peptide corresponding to 18 amino acids from the N-terminal, extracellular domain of human CD4.
Application
Quality Control Testing
Evaluated by Western Blotting in HL-60 cell lysate.
Western Blotting Analysis: A 1:1,000 dilution of this antibody detected CD4 in HL-60 cell lysate.
Tested Applications
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected CD4 in THP-1 cell lysate.
Flow Cytometry Analysis: 0.1 μg from a representative lot detected CD4 in one million THP-1 cells.
Affinity Binding Assay: A representative lot of this antibody bound CD4 peptides with a KD of 4.5 x 10-8 in an affinity binding assay.
Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected CD4 in human spleen and human colon tissue sections.
Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected CD4 in THP-1 cells.
Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user

Target description
T-cell surface glycoprotein CD4 (UniProt: P01730; also known as T-cell surface antigen T4/Leu-3, CD4) is encoded by the CD4 gene (Gene ID: 920) in human. CD4 is a single-pass type I membrane glycoprotein that is highly expressed in T-helper cells and is also found in macrophages, dendritic cells, and NK cells. CD4 is synthesized with a signal peptide (a 1-25), which is subsequently cleaved off to generate the mature form that has an extracellular domain (aa 26-396), a transmembrane domain (aa 397-418), and a cytoplasmic domain (aa 419-458). It has three Ig-like C2-type and one Ig-like V-type domain. CD4 plays an essential role in the immune response and serves multiple functions in response against both external and internal offenses. In T-cells, it functions primarily as a coreceptor for MHC class II molecule:peptide complex. It interacts simultaneously with the T-cell receptor (TCR) and the MHC class II presented by antigen presenting cells and recruits the Src kinase LCK to the vicinity of the TCR-CD3 complex. The LCK can then initiate different intracellular signaling events by phosphorylating various substrates, which lead to lymphokine production, motility, adhesion and activation of T-helper cells. CD4 is also reported to participates in the development of T-helper cells in the thymus and trigger the differentiation of monocytes into functional mature macrophages. CD4 also serves a primary receptor for human immunodeficiency virus-1 (HIV-1). It is removed from plasma membrane by Nef protein of HIV-1, which increases clathrin-dependent endocytosis and lysosomal degradation of CD4. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
