CD4 antibodies, mouse

CD4 antibodies, mouse

Clone: REA604 | Dilution: 1:10
Clone REA604 recognizes the mouse CD4 antigen, a cell surface glycoprotein, which is a member of the immunoglobulin superfamily. It is also known as L3T4 or Leu-3. In mice, CD4 is expressed on T helper cells, regulatory T cells, and at lower levels on subpopulations of NKT cells and dendritic cells. It is furthermore detected on most thymocytes (CD4
and CD4
thymocytes). CD4 interacts with MHC class II molecules on the surface of antigen-presenting cells. It increases the avidity of the interaction between T cells and antigen-presenting or target cells.
Additional information: Clone REA604 displays negligible binding to Fc receptors.

In order to compare the epitope specificity of REAfinity Clone REA604 with other known clones, a competition assay was performed.
 Cells were incubated with an excess of purified unconjugated REAfinity Antibody followed by staining with fluorochrome-conjugated antibodies of other known clones against the same marker. Based on the fluorescence signal obtained, the clones were identified as recognizing completely overlapping (++), partially overlapping (+), or completely different epitopes (-) of the marker.
