A new method for on-chip sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) of proteins is reported. Miniaturization of SDS-PAGE has attracted significant attention because it offers rapid analysis times, excellent resolution, high throughput, and the potential for integration and automation, as compared to conventional counterparts. The presented on-chip SDS-PAGE technique em...

The aim of the study was to describe the urinary electrophoretic pattern of dogs with heartworm disease.Urine samples from 15 heartworm-infected and 15 healthy dogs were taken. Urinary specific gravity, urinaryprotein concentration and the urine protein/creatinine (U P/C) ratio were determined. Urine proteins werefractionated using SDS-PAGE. Results showed statistically significant differences ...

Objective(s) Staphylococcus aureus is a foremost source of numerous nosocomial and community acquired infections. Antibiotic therapy for vancomycin resistant S. aureus (VRSA) can not promise the eradication of infections. Since adhesion is the major route of infections, adhesin based vaccine could suppress S. aureus infections. Fibronectin binding protein A (FnBPA) and clumping factor A (ClfA)...

Two-dimensional gel electrophoresis (2DE) and SDS-PAGE are the two most useful methods in protein separation. Proteins separated by 2DE or SDS-PAGE are usually transferred to membranes using a variety of methods, such as electrophoretic transfer, heat-mediated transfer, or nonelectrophoretic transfer, for specific protein detection and/or analysis. In a recent study, Pettegrew et al. claim to r...

In this report we describe a novel approach to the mass spectrometric analysis of whole proteins from gels. The strategy consists of three components: conventional SDS-PAGE gels, reversible negative staining procedures, and passive elution of proteins from gels followed by mass spectrometric analysis. Protein bands are excised from SDS-PAGE gels, destained, and extracted. For gel loadings > or ...

A rapid method for the analysis of carbohydrate-protein interactions by using fluorescent labeling and SDS-PAGE was developed. The N-acetyl-beta-D-glucosamine-WGA complex and alpha-D-mannose-Con A complex were labeled with 8-aminonaphthalene-1,3,6-trisulfonate (ANTS). The protein band displaying fluorescence with ultraviolet illumination was seen after SDS-PAGE.

we have modified one of the most useful methods of protein separation; namely, two dimensional gel electrophoresis (2-de). this modified version of 2-de is not only simpler and easier but also faster than all the currently available methods. in this method, isoelectric focusing is carried out in the first dimension using a vertical sodium dodecyl sulfate polyacrylamide gel electrophoresis (sds-...

Background Human coagulation factor IX is a 57kDa plasma serine protease made in Liver which plays a vital role in the blood coagulation cascade. FIX deficiency causes severe disorder Hemophilia B or Christmas disease. Nowadays, recombinant proteins have important roles in treatment of diseases. Although, cultivated mammalian cells because of their ability for producing properly folded protein ...
