Improved consistency in 2D gel electrophoresis: Sheep plasma as a test case

2D Gel Electrophoresis - An Overview

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. ...

2D Electrophoresis Gel Image and Diagnosis of a Disease

The process of diagnosing a disease from the 2D gel electrophoresis image is a challenging problem. This is due to technical difficulties of generating reproducible images with a normalized form and the effect of negative stain. In this paper, we will discuss a new concept of interpreting the 2D images and overcoming the aforementioned technical difficulties using mathematical transformation. T...

Gradient gel electrophoresis of human plasma lipoproteins.

A rapid and simple method for separating and identifying plasma lipoproteins is described. The technique utilizes the “molecular sieving” properties of continuous concave gradient electrophoresis on a slab of polyacrylamide (4 to 26%) gel. Gradient gel electrophoresis is particularly suitable for separating lipoproteins according to their molecular weight. The technique can be used to demonstra...
