Identification of meat species by SDS-polyacrylamide gel electrophoresis.

SDS Polyacrylamide Gel Electrophoresis of Proteins.

Probably the most widely used of techniques for analyzing mixtures of proteins is SDS polyacrylamide gel electrophoresis. In this technique, proteins are reacted with the anionic detergent, sodium dodecylsulfate (SDS, or sodium lauryl sulfate) to form negatively charged complexes. The amount of SDS bound by a protein, and so the charge on the complex, is roughly proportional to its size. Common...

Identification of L Forms by Polyacrylamide - Gel Electrophoresis THEODORE

Crude membranes were obtained from L forms by allowing the cells to lyse in distilled water. The crude membranes were washed several times in distilled water, lyophilized, and extracted with phenol-acetic acid-water. The membrane proteins were separated electrophoretically in polyacrylamide gels run at pH 4.5. Electrophoretic patterns and densitometric tracings of the gels showed distinct, repr...

Characterization of Bothrops Venoms of Argentina by Sds-polyacrylamide Gel Electrophoresis

Electrophoretic pattern of Bothrops alternatus, B.neuwiedi, B. ammodytoides, B. jararaca and B. jararacussu of Argentina by SDS-Polyacrylamide gel electrophoresis was carried out. Venoms used in this study came from animals (including juvenile) which live in different geographical zones. Special care was taken to not have cross-contamination of samples with blood and tissue fluids. All the snak...
