Western blot of GABRB3 in rat hippocampal lysate showing specific immunolabeling of a band at ~58 kDa corresponding to Phospho-GABRB3 (Ser408, Ser409) polyclonal antibody (Product # PA5-35390) in the first lane (-). Phosphospecificity is shown in the second lane (+) where immunolabeling is blocked by pre-adsorption of the phosphopeptide used as the antigen, but not by the corresponding non-phosphopeptide (not shown).
