I've operated left side and collected left part of the brain and I've  been used RIPA buffer for homogenization and centrifuged at 10,000 rpm for 20 min,the occlusion period is 60 min.all my 24hr samples(whole cell lysate) are showing significant decrease in  P-JNK expression,which is contradictory to available data .Is this technical problem or natural .If anyone had encountered same problem please help me out.
