(G) Western blotting of the supernatant (S) and pellet (P) protein fractions from the C. elegans carrying the SOD1G85R transgene with the double mutation ufd-2(tm1380);spr-5(by134) compared with controls. While SOD1G85R protein levels are unchanged in the S fraction, those in the P fraction are decreased in the double suppressor mutant. The P fraction represents only about 1.7% of total SOD1G85R in the WT sample; therefore, a higher ratio of the P fraction relative to the S fraction (approximately 2:1) is used for the western analysis.
