This work introduces a novel active contour-based scheme for unsupervised segmentation of protein spots in two-dimensional gel electrophoresis (2D-GE) images. The proposed segmentation scheme is the first to exploit the attractive properties of the active contour formulation in order to cope with crucial issues in 2D-GE image analysis, including the presence of noise, streaks, multiplets and fa...
In proteomics research still two-dimensional gel electrophoresis (2D-GE) is currently used for biomarker discovery. We applied free flow electrophoresis (FFE) separation technology combined with biomolecular interaction sensing using Surface Plasmon Resonance (SPR) imaging in an integrated proteomics-on-a-chip device as a proof of concept for biomarker discovery.
BACKGROUND Proteomic analysis is emerging as a highly useful tool in food research, including studies of food allergies. Two-dimensional gel electrophoresis involving isoelectric focusing and sodium dodecyl sulfate polyacrylamide gel electrophoresis is the most effective method of separating hundreds or even thousands of proteins. In this study, albumin and globulin tractions of pea seeds cv. R...
The reproducibility of conventional two-dimensional (2D) gel electrophoresis can be improved using differential in-gel electrophoresis (DIGE), a new emerging technology for proteomic analysis. In DIGE, two pools of proteins are labeled with 1-(5-carboxypentyl)-1'-propylindocarbocyanine halide (Cy3) N-hydroxy-succinimidyl ester and 1-(5-carboxypentyl)-1'-methylindodi-carbocyanine halide (Cy5) N-...
The reactive aldehyde, 4-hydroxynonenal (HNE), is a product of lipid peroxidation that can covalently modify and inactivate proteins. Previously, we reported increased HNE modification of select retinal proteins resolved by one-dimensional gel electrophoresis in aged Fisher 344 x Brown Norway rats (Louie, J.L., Kapphahn, R.J., Ferrington, D.A., 2002. Proteasome function and protein oxidation in...
In the nowadays mainly mass spectrometry-driven world of Proteomics, one can frequently read and hear that 2D gel-based electrophoresis methods are no longer used for proteome analysis. This short review is a compilation of facts why the gel-based workflow is not dead.
