Identification of a Small Compound Targeting PKM2-Regulated Signaling Using 2D Gel Electrophoresis-Based Proteome-wide CETSA

Evaluation of two-dimensional gel electrophoresis-based proteome analysis technology.

Proteome analysis is most commonly accomplished by a combination of two-dimensional gel electrophoresis (2DE) to separate and visualize proteins and mass spectrometry (MS) for protein identification. Although this technique is powerful, mature, and sensitive, questions remain concerning its ability to characterize all of the elements of a proteome. In the current study, more than 1,500 features...

2D Gel Electrophoresis - An Overview

Insight of Saffron Proteome by Gel-Electrophoresis.

Saffron is a spice comprised of the dried stigmas and styles of Crocus sativus L. flowers and, since it is very expensive, it is frequently adulterated. So far, proteomic tools have never been applied to characterize the proteome of saffron or identify possible cases of fraud. In this study, 1D-Gel Electrophoresis was carried out to characterize the protein profile of (i) fresh stigmas and styl...

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...

Geometric Alignment of 2D Gel Electrophoresis Images

OBJECTIVES 2D gel electrophoresis (2-DE) is the method of choice for analyzing protein expression in the field of proteomics, for example, comparing a reference with a test population. However, due to complex physical and chemical processes the locations of proteins generally vary in different 2-DE images. To cope with these variations, accurate geometric alignment of 2-DE images is important. ...
