(a) Brains of the 'rescued' mice (Becn1−/−; Becn1EGFP/+) and of control Becn1+/+ littermates were lysed and subjected to immune isolation using an anti-GFP antibody. Proteins bound to anti-GFP antibody were isolated, detected and identified by SDS-PAGE, Coomassie brilliant blue staining and mass spectrometry. Seven bands pulled down by anti-GFP antibody specifically from 'rescued' mice lysate are numbered (this is a copy of image from our previous report with modification).
