UC Davis School of Medicine 2 articles published in JoVE Biochemistry Acyl-PEGyl Exchange Gel Shift Assay for Quantitative Determination of Palmitoylation of Brain Membrane Proteins David J. Speca1, Elva Diaz1 1Department of Pharmacology, UC Davis School of Medicine Palmitoylation entails the incorporation of a 16-carbon palmitate moiety to cysteine residues of target proteins in a reversible manner. Here, we describe a biochemical approach, the acyl-PEGyl exchange gel shift (APEGS) assay, to investigate the palmitoylation state of any protein of interest in mouse brain lysates. Biology Ground State Depletion Super-resolution Imaging in Mammalian Cells Rose E. Dixon1, Oscar Vivas1, Karen I. Hannigan1, Eamonn J. Dickson1 1Department of Physiology and Membrane Biology, University of California School of Medicine, Davis This article outlines a protocol for the detection of one or more plasma and/or intracellular membrane proteins using Ground State Depletion (GSD) super-resolution microscopy in mammalian cells. Here, we discuss the benefits and considerations of using such approaches for the visualization and quantification of cellular proteins.
