Extended validation for CD154 Antibody, anti-human, REAfinity™

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.

TRAP1+
Cells were incubated with an excess of purified unconjugated CD154 (REA238) 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 CD154. Human peripheral blood mononuclear cells (PBMCs), stimulated with 1 µg/mL SEB and 1 µg/mL CD40 for 6 hours, were stained with CD154 antibodies and with a suitable counterstaining. As a control, CD154 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.

Fixation data
To provide an indication on how an antibody performs after fixation of cells, in-house data on staining results before and after fixation with 3.7% formaldehyde using Miltenyi Biotec antibodies are provided. Different experimental settings may lead to different results.

Specifications for CD154 Antibody, anti-human, REAfinity™

Overview

Clone REA238 recognizes the human CD154 antigen, a 39 kDa transmembrane glycoprotein, also known as CD40L, gp39, T-BAM, TRAP, or Ly-62, which is a proinflammatory and prothrombotic ligand in the tumor necrosis factor family. CD154 is transiently up-regulated on activated CD4
+
T cells and plays an important role as a costimulatory molecule in T cell/antigen-presenting cell interactions through ligation of CD40. It mediates B cell proliferation in the absence of co-stimulus as well as IgE production in the presence of IL-4.
Additional information: Clone REA238 displays negligible binding to Fc receptors.
