Evaluating the efficacy of subcellular fractionation of blast cells using live cell labeling and 2D DIGE

Methods Mol Biol. 2012:854:319-32. doi: 10.1007/978-1-61779-573-2_22.

Abstract

Labeling of exposed cell surface proteins of live cells using CyDye DIGE fluor minimal dyes is an efficient strategy for cell surface proteome profiling and quantifying differentially expressed proteins in diseases. Here we describe a strategy to evaluate a two-step detergent-based protein fractionation method using live cell labeling followed by visualization of the fluorescently labeled cell surface proteins and fractionated proteins within a single 2D gel.
