Recombinant DDX21 Antibody (Ab099417) - Western Blot All lanes: Recombinant DDX21 Antibody (Ab099417) at 1/1000 dilution Samples: Lysates at 20 µg per lane Secondary: Goat Anti-Rabbit IgG H&L (HRP) (Ab170144) at 1/20000 dilution
Predicted band size: 87 kDa Observed band size: 70-110 kDa DDX21 can bind to RNA and form specific motifs, which may result in a band shift phenomenon in a Western blot experiment. This shift occurs because the binding of RNA to DDX21 alters the size and charge of the protein-RNA complex, affecting its migration during gel electrophoresis. Exposure time: 34.8 s
