Binding assay determination of the signal to noise ratio (SNR) of V5-labeled Ankyrons® CY40395 binding to 0.5 picomoles of immobilised Q8VHM7_MOUSE, over a background (BG) of non-cognate target protein. The Ankyron was pre-conjugated with the ProImmune Anti-V5 HRP label reagent before detection with a chemiluminescence substrate.
