Proteasome subunit levels in rat E18 primary cortical neuronal cultures. Aliquots of the supernatant (cleared lysate) and pellet fractions obtained from samples prepared for the “in-gel” assay (see Fig. 1) were run on SDS-PAGE (10% gel) followed by immunobloting with the same antibodies listed in Fig. 1 as well as with anti-β-actin. 40 μg of protein were loaded per lane.
