Proteomic characterization of hydatid cyst fluid: two-dimensional electrophoresis (2-DE) setup through optimizing protein extraction

Two-Dimensional Gel Electrophoresis (2-DE)

Two-dimensional gel electrophoresis (2-DE) is able to separate hundreds to thousands of proteins or polypeptides by coupling IsoElectric Focusing (IEF) in first dimension and Sodium Dodecyl Sulphate PolyAcrylamide-Gel Electrophoresis (SDS-PAGE) in second dimension. This particular configuration is called classical 2-DE: IEF separates proteins in function of their isoelectric point (pI) and SDS-...

Purification and Immunobiochemical Characterization of Sheep Hydatid Cyst Fluid Antigen

In the present study, sheep crude hydatid cyst fluid antigen (SCHCFA) was prepared by ammonium sulfate precipitation, centrifugation and dialysis. SDS-PAGE of SCHCFA showed seven polypeptides of 72.8 kDa, 66.5 kDa, 60.2 kDa, 41 kDa, 25.1 kDa, 19 kDa and 8 kDa when stained with Coomassie briliant Blue R-250. The initial part of the ascending loop of the first peak (PI) when resolved by gel filtr...

Two–Dimensional Gel Electrophoresis of Ceolomic Fluid of Eisenia foetida Earthworm

Earthworms possess antioxidant, antibacterial, antitumor, and hemolytic properties. To recognize the molecules responsible for various biological activities of earthworm’s coelomic fluid, a detailed knowledge about its protein contents is required. The aim of this study was to characterize the proteins present within the coelomic fluid of Eisenia foetida earthworm. Polyacrylamide-gel-elec...

Chemical Composition of Hydatid Cyst Fluid of Echinococcus granulosus

characterization of purified glutathione s-transferase (gsts) from fasciola hepatica and liver tissue by two-dimensional electrophoresis (2-de)

two-dimensional electrophoresis (2-d electrophoresis) is a powerful and extensively used method for analysis of complex protein mixtures extracted from cells, tissue, or other biological samples such as helminth parasites including, f. hepatica. each spot on the resulting two-dimensional collection corresponds to a single protein species in the sample. this study was carried out to detect of gs...
