WebProtein extraction and sample cleanup are the most important steps to ensure optimal resolution and reduce variability of your 2-D gels. 2-D PAGE success depends on sample purity. Interfering substances that can negatively impact SDS-PAGE and 2-DGE include salts, detergents, denaturants, or organic solvents, so it is crucial to eliminate these ...

WebAspirate the PBS, then add ice-cold lysis buffer (1 mL per 10 7 cells/100 mm dish/150 cm 2 flask; 0.5 mL per 5x10 6 cells/60 mm dish/75 cm 2 flask). Scrape adherent cells off … DTT is a reducing agent; once oxidized, it forms a stable six-membered ring with an internal disulfide bond. It has a redox potential of −0.33 V at pH 7. The reduction of a typical disulfide bond proceeds by two sequential thiol-disulfide exchange reactions and is illustrated below. The reduction usually does not stop at … See more Dithiothreitol (DTT) is the common name for a small-molecule redox reagent also known as Cleland's reagent, after W. Wallace Cleland. DTT's formula is C4H10O2S2 and the chemical structure of one of its See more DTT is used as a reducing or "deprotecting" agent for thiolated DNA. The terminal sulfur atoms of thiolated DNA have a tendency to … See more • 2-Mercaptoethanol (BME) • TCEP See more DTT is unstable in ambient atmospheric conditions as it is oxidized by oxygen; DTT should be stored and handled under inert gasses to prevent oxidation.
