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 (REA623) 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. Human peripheral blood mononuclear cells (PBMCs) 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. Monocytes were excluded from the analysis. 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-human, REAfinity™

Overview

Clone REA623 recognizes the human CD4 antigen, a 55 kDa single-pass type I membrane protein, also known as T4/Leu-3. CD4 is highly expressed on T helper cells and at a lower level on monocytes and dendritic cells. It is involved in the recognition of MHC class II/peptide complexes by the TCR heterodimers and is the receptor for the human immunodeficiency virus (HIV).
Additional information: Clone REA623 displays negligible binding to Fc receptors.

Alternative names

T4, Leu-3, CD4mut
