Gel electrophoresis is a standardized technique that routinely used in many daily needs, such as clinical laboratories, forensic and industry, molecular biology biochemistry, conservational biology, medicine. This paper reviews several types of techniques, with two mostly being agarose acrylamide gel electrophoresis, either isotopic or non-isotopic based analysis. exploits the difference size c...

Objective: To explore a fast and sensitive method for screening T cell receptor (TCR) biases through comparison of silver staining for polyacrylamide gel electrophoresis and ethidium bromide staining for agarose gel electrophoresis. Methods: The lymphocytes were isolated from peripheral blood which collected from ten patients with T1DM; the total RNA was extracted followed by transformed to cDN...

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-...

Curli, consisting primarily of major structural subunit CsgA, are functional amyloids produced on the surface of Escherichia coli, as well as many other enteric bacteria, and are involved in cell colonization and biofilm formation. CsgE is a periplasmic accessory protein that plays a crucial role in curli biogenesis. CsgE binds to both CsgA and the nonameric pore protein CsgG. The CsgG-CsgE com...

background: rapid diagnosis and differentiation of brucella is of high importance due to the side effects of antibiotics for the treatment of brucellosis. this study aimed to identify and compare pcr-elisa as a more accurate diagnositc test with other common molecular and serological tests. methods: in this experimental and sectional study, during march 2014 to sep 2015, 52 blood samples of sus...

We describe an improved, fast, automated method for screening large genes such as BRCA2 for germline genomic mutations. The method is based on heteroduplex analysis, and has been adapted for a high throughput application by combining the fluorescent technology of automated sequencers and robotic sample handling. This novel approach allows the entire BRCA2 gene to be screened with appropriate ov...

The present paper is concerned with a correlation between clinical parameters of multiple sclerosis and different agar gel electrophoretical patterns in CSF. The agar gel electrophoresis represents clearly the most sensitive method for the demonstration of oligoclonal bands in CSF.

Electrophoresis is the migration of charged particles or molecules in an electric field. This occurs when the substances are in aqueous solution. The speed of migration is dependent on the applied electric field strength and the charges of the molecules. Thus, differently charged molecules will form individual zones while they migrate. In order to keep diffusion of the zones to a minimum, elect...
