Mouse Anti-EDA Recombinant Antibody (clone EctoD1) (CAT#: FAMAB-0123CQ)

Figure 1 Anti-EDA antibodies recognize epitopes on native EDA1

A, SDS-PAGE analysis and Coomassie Blue staining of 10 μg/lane of the indicated purified mouse IgG1 monoclonal antibodies under reducing conditions. Migration positions of molecular mass standards (in kDa) are shown. B, Fc-EDA1 (200 or 50 ng) and Fc-hAPRIL (Fc-A, 500 ng) were resolved by Western blotting (WB) under reducing conditions and revealed with anti-human immunoglobulin (anti-Fc), anti-EDA (Renzo2, EctoD1, EctoD2, or EctoD3), or anti-APRIL (Aprily2) antibodies.

Figure 2 Anti-EDA antibodies recognize epitopes on native EDA1

Purified Fc-EDA1 and Fc-APRIL proteins were coated directly in an ELISA plate. Fc-EDA1 was also captured via the Fc portion using an anti-human antibody. Coated proteins were revealed with the indicated antibodies at the indicated concentrations.

Figure 3 Anti-EDA antibodies EctoD2 and EctoD3 recognize epitopes overlapping the EDA receptor-binding site.

Fc-EDA1 WT or containing the indicated point mutations, or Fc-BAFF as a control, were coated onto ELISA plates and revealed with the indicated antibodies at the indicated concentration.

Figure 4 Anti-EDA monoclonal antibodies EctoD2 and EctoD3 inhibit mammalian and avian EDA1 and EDA2.

Receptors (human or chicken EDAR or XEDAR) fused to the GPI anchor of TRAILR3 were expressed in 293T cells together with an EGFP tracer (x axis). Cells were stained with or without cell supernatants containing Fc-EDA1 or Fc-EDA2 of human/mouse (human) or chicken origin (y axis). The interactions of Fc-EDAs with GPI-anchored receptors were challenged by preincubation of the ligand with anti-EDA antibodies (EctoD1, EctoD2, and EctoD3) or with an irrelevant antibody (anti-APRIL). Both scattergram axes show fluorescence intensity on a logarithmic scale (10⁰–10⁴).

Figure 5 Anti-EDA monoclonal antibodies EctoD2 and EctoD3 inhibit mammalian and avian EDA1 and EDA2.

FLAG-EDA1 was diluted at the indicated concentrations and preincubated with or without 125 ng/ml concentration of anti-EDA (Renzo2, EctoD1, EctoD2, or EctoD3) or anti-APRIL (Aprily2) monoclonal antibodies. The binding of FLAG-EDA1 to coated EDAR-Fc protein was then probed by an ELISA-like assay.

Figure 6 Anti-EDA monoclonal antibodies EctoD2 and EctoD3 inhibit mammalian and avian EDA1 and EDA2.

EDA1-sensitized Jurkat JOM2 EDAR-Fas reporter cells were incubated in the presence of the indicated concentrations of Fc-EDA1, in the presence or absence of the indicated concentrations of anti-EDA monoclonal antibodies EctoD1, EctoD2, or EctoD3. Cell viability was determined by colorimetry (phenazine methosulfate/(3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium assay) and expressed as percentage of maximal survival.
