Figure 4From: Characterization of maturation of neuronal voltage-gated sodium channels SCN1A and SCN8A in rat myocardium Analysis of SCN1A protein expression. In contrast to rtPCR results, Western blot analysis of SCN1A protein expression showed a progressive decline with postnatal development (upper panel). As a control, protein expression of GAPDH showed no changes with development (lower panel; abbreviations as depicted in Figure 1).Back to article page
