MDA-5 antibody | knockout validation | Cell Signaling 5321

This is a knockout-validated antibody summary, based on publications "The RNA genome of hepatitis E virus robustly triggers antiviral interferon response", as cited below [1], "DNA hypomethylation promotes transposable element expression and activation of immune signaling in renal cell cancer" for western blot knockout validation (figure 4a) [2], and "cGAS and DDX41-STING mediated intrinsic immunity spreads intercellularly to promote neuroinflammation in SOD1 ALS model" for western blot knockout validation (figure 3a) [3]. Labome curates formal publications to compile a list of antibodies with unambiguous specificity within Validated Antibody Database (VAD).
