*  "Diversity of Helicobacter pylori among Chinese persons with H. pylori " by Javed Yakoob, Guo Ling Hu et al.
To determine whether there is diversity among clinical isolates of Helicobacter pylori in Chinese patients with peptic ulcer disease, 40 strains of H. pylori were isolated from antral biopsy specimens obtained at the gastroenterology clinic of Xiangya Hospital from January 1996 to June 1998. Total protein profile by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and DNA diversity by polymerase chain reaction-random amplified polymorphic DNA (PCR-RAPD) fingerprinting were performed with these isolates. All the isolates from peptic ulcer disease were relatively homogeneous in protein profiles, but they showed a great DNA sequence diversity by PCR-RAPD fingerprinting. In Chinese patients H. pylori demonstrated an enormous diversity. The diversity among clinical isolates of H. pylori could be distinctly demonstrated and this observation will be helpful in the management of intrafamilial and recurrent H. ...

Quickly the shell and meats of each varieties had been combined in 1 M phosphate-buffered saline (pH 7.2) and extracted overnight in 4 °C under regular blending. The homogenates had been centrifuged at 14 000 rpm at 4 °C for a quarter-hour. The supernatants had been sterile-filtered lyophilised and kept at after that ?20 °C until make use of. For preparation of the boiled extracts the homogenates of the prawns were boiled for 5 minutes before extraction as described above. The protein concentration of each extract was decided using the Total Protein Kit (Sigma-Aldrich UK) and bovine serum albumin as a standard. SDS-PAGE of prawn extracts Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) was performed as described by Nakano et al. (17) with some modifications. The samples of the extracts ...

The giardins are a family of approximately 30000 Mr structural proteins found in microribbons attached to microtubules in the disc cytoskeleton of Giardia. After examining the solubility of giardins in various agents, a method has been developed to extract these polypeptides and subsequently precipitate them selectively. The giardin chains are soluble in 10 mM-HEPES/EDTA buffer at high pH and low ionic strength, but become insoluble in 10 mM-MES/EDTA buffer at pH 6.7 when the ionic strength is raised above 50 mM salt. By dialysing giardin extracts in turn against dissociating and reassembly buffers, the purification is obtained of a subset of giardin chains identified by sodium dodecyl sulphate/polyacrylamide gel electrophoresis as the cytoskeleton bands 14a, 14b and 15. The structures forming under assembly conditions are all composed of fine filaments, 2-3 nm in diameter. Filaments after the first cycle of assembly are ...

SDS-Polyacrylamide Gel Electrophoresis is a technique to separate proteins according to elctrophoretic mobility - a function of polypeptide chain length or protein mass). SDS-Polyacrylamide Gel Electrophoresis can also be used to separate DNA and RNA molecules.. SDS stands for sodium dodecyl sulfate. "SDS is an anionic detergent that disrupts non-covalent interactions in native proteins." SDS is used to create denaturing conditions to separate proteins by molecular weight and also confers negative charge to the proteins in proportion to its mass. By denaturing the proteins with SDS, proteins can be separated by their mass alone; without SDS, other molecular properties, such as a charge and shape, would interfere with the separation process (proteins that are strongly negative, for example, would move faster down a ...

I am planning to run a Blue Native gel, followed by electroblotting for Western analysis. I have read that the Coomassie blue that binds proteins in Blue Native electrophoresis interferes with protein transfer to a membrane. Yet, there are many reports of transfer from BN gels. Does anyone have experience with this procedure who could give me some tips? And is it possible that a nitrocellulose membrane presents more of a problem than PVDF? Thanks for any help.

We had run a total protein SDS PAGE . After staining we saw a new & different band in one of the PAGE columns . Now we want to repurificate the protein ( the new band ) from the poly acrylamide gel . how should we do it ??we need the protein to re run on low voltage SDS PAGE for better isolation . how can we elute the protein in an economical & fast way ???/ thanks for your help .

Abstract: A correlation between the relative electrophoretic mobility of 15 proteins and the concentration of polyacrylamide gel was considered. The extrapolation of straight lines to the zero mobility enabled to determine the effective radius of protein molecules and the extrapolation to the zero concentration of the gel was used to estimate the free electrophoretic mobility. Use of the method for study of protein molecules is discussed ...
*  Proteomics/Protein Separations- Electrophoresis/Gel Electrophoresis - Wikibooks, open books for an open world
Gel electrophoresis (GE) is used to differentiate molecular entities depending on their physical characteristics. These defining characteristics include the size, shape, charge and isoelectric point. Isoelectric point is perhaps the most important characteristic; it is the point at which the overall electric force on the analyte is 0, and hence the point at which the analyte ceases migration within the gel. Gel electrophoresis is used as an analytical technique or as a preparatory technique to purify molecules before they are used for other methods like mass spectrometry is based on the principle that, when charged molecules are placed in an electric field, they migrate toward either the positive or negative pole depending on their charge. Since nucleic acids are negatively charged due to their phosphate groups they migrate ...
