We describe a system, both hardware and software, that provides quantitative analysis and data reduction of two-dimensional electrophoresis gels. Image-analysis techniques are used to determine spot intensities and to match spot patterns among many gels. A pattern-recognition program is used to extract the useful information contained in the spot lists. The application of this technology to a s...
INTRODUCTION SDS-polyacrylamide gel electrophoresis (SDS-PAGE) represents the second-dimension separation of two-dimensional (2D)-PAGE. Large-scale proteome analysis usually requires simultaneous electrophoresis of batches of second-dimension SDS-PAGE gels to maximize the reproducibility of 2D electrophoresis protein profiles. This requirement is most easily met using multiple, vertical second-...
Injectable bone fillers have emerged as an alternative to the invasive surgery often required to treat bone defects. Current bone fillers may benefit from improvements in dynamic properties such as shear thinning during injection and recovery of material stiffness after placement. Negatively charged inorganic hydroxyapatite (HAp) nanoparticles (NPs) were assembled with positively charged organi...
The protein pattern of cerebrospinal fluid (CSF) of 334 patients with various neurological and systemic diseases was investigated by high resolution two-dimensional electrophoresis (2-DE). 2-DE gels of normal CSF contain proteins which are not detectable in 2-DE gels of serum. Disturbances of the blood-brain or blood-CSF barrier, and degenerative diseases of the brain and malignant diseases pro...
Changes in plastid polypeptide composition during greening of etiolated peas were investigated by two-dimensional gel electrophoresis. One hundred of the more than 250 polypeptides which could be detected upon silver staining were followed during plastid development. Thirty-nine polypeptides decreased in abundance on a per organelle basis. Twentythree of the 46 polypeptides which increased in a...
Excessive water production through fractures become an important problem in oil exploration of fractured reservoirs. For this purpose, polymer gels were prepared by crosslinking of aqueous solutions of polymer and crosslinker for the purpose of water management in high water cut fractured reservoirs. A copolymer of sulfonated polyacrylamide was used as polymer and chromium triacetate (Cr(OA...
BACKGROUND Extended culture of monocytes and fibroblasts in three-dimensional collagen gels leads to degradation of the gels (see linked study in this issue, "Fibroblasts and monocytes contract and degrade three-dimensional collagen gels in extended co-culture"). The current study, therefore, was designed to evaluate production of matrix-degrading metalloproteinases by these cells in co-culture...
Transmembrane 4 L six family member 5 (TM4SF5) is highly expressed in hepatocellular carcinoma tissues and enhances migration in two-dimensional environments. Here, we investigated how TM4SF5 is involved in diverse pro-metastatic phenotypes in in vivo-like three-dimensional (3D) extracellular matrix gels. TM4SF5-positive cells aggressively formed invasive foci in 3D Matrigel, depending on TM4SF...
