Specificity

Epitope competition
In order to compare the epitope specificity of an antibody, the clone being used is compared with other known clones recognizing the same antigen in a competition assay.

Cells were incubated with an excess of purified unconjugated CD4 (REA604) 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.

Sensitivity

Performance comparison
Selected fluorochrome conjugated antibodies from Miltenyi Biotec were compared to commercially available hybridoma clones in flow cytometry analysis.

Flow cytometric comparison of different clones for CD4. Splenocytes from BALB/c mice were stained with CD4 antibodies and with a suitable counterstaining. As a control, CD4 antibody staining was omitted and cells were measured in the same channels. Flow cytometry was performed with the MACSQuant® Analyzer. Cell debris, dead cells, and cell doublets were excluded from the analysis based on scatter signals and 4',6-diamidino-2-phenylindole (DAPI) fluorescence. No FcR Blocking Reagent was used. The recommended titers of respective antibodies from different suppliers were used.

Specifications for CD4 Antibody, anti-mouse, REAfinity™

Overview

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
+
CD8
+
and CD4
+
CD8
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.
