Fig 2: ELISA Analysis: 100 ng/well of receptor or control is coated on a 96-well plate. After blocking, ligand is titrated 2-fold in series, and detected with anti-flag antibody. TRAIL (Prod # ALX-522-003) shows positive for binding to TRAIL-R2 and negative for binding to either Fc control protein (Prod # ALX-203-004) and buffer control.
