Optimization of large gel 2D electrophoresis for proteomic studies of skeletal muscle

Optimization of 2-dimensional gel electrophoresis for proteomic studies of solid tumor tissue samples.

The method of 2‑dimensional gel electrophoresis (2-DE) has been widely used for the proteomic profiling of solid biological samples, however, the analytical conditions have not been optimized. The present study optimized the major conditions of 2‑DE for determining the protein contents of solid tumor tissues, through enhancement of the separation efficiency and resolution. Three major analytica...

2D Gel Electrophoresis - An Overview

Comparative Skeletal Muscle Proteomics Using Two-Dimensional Gel Electrophoresis

The pioneering work by Patrick H. O'Farrell established two-dimensional gel electrophoresis as one of the most important high-resolution protein separation techniques of modern biochemistry (Journal of Biological Chemistry1975, 250, 4007-4021). The application of two-dimensional gel electrophoresis has played a key role in the systematic identification and detailed characterization of the prote...

Proteomic profiling of macrophages by 2D electrophoresis.

The goal of the two-dimensional (2D) electrophoresis protocol described here is to show how to analyse the phenotype of human cultured macrophages. The key role of macrophages has been shown in various pathological disorders such as inflammatory, immunological, and infectious diseases. In this protocol, we use primary cultures of human monocyte-derived macrophages that can be differentiated int...

Segmentation of 2d-gel Electrophoresis Images

Introduction Two-Dimensional Gel Electrophoresis technique is a convenient and well-established method to separate thousands of proteins on polyacrylamide gels, according to the differences in their net charge and their molecular mass [1]. Its digital output is an image which depicts proteins as bright or dark spots over a noisy and inhomogeneous background. Each protein is characterized by its...
