Effect of Anionic Polyacrylamide on the Structural
Taking the superfine tailings slurry (STS), fine tailings slurry (FTS), and unclassified tailings slurry (UTS) of a gold mine as examples, a series of laboratory shear tests were conducted to investigate the effect of anionic polyacrylamide (APAM) on the structural stability of the thickened tailings slurry in pipeline transportation.

Get Price- How is native polyacrylamide gel electrophoresis performed?
- Native polyacrylamide gel electrophoresis is performed using 6% acrylamide gels in Tris‐boric‐EDTA (8.9 m M Tris base, 8.9 m M boric acid, 0.2 m M Na 2 EDTA) buffer, pH 8, as described by Laemmli (1970). Staining for GSNOR activity is carried out using a modification of the method reported by Seymour and Lazarus (1989) and Fernández et al (2003).
- How do you make a polyacrylamide gel?
- Prepare a 5x stock solution in 1 liter of H2O. The 1×working solution is 25 mM Tris-Cl/250 mM glycine/0.1% SDS. Use Tris-glycine buffers for SDS-polyacrylamide gels. 55°C. Assemble the glass plates according to the manufacturer’s instructions. Determine the volume of the gel mold (this information is usually provided by the manufacturer).
- What is a polyacrylamide gel?
- Polyacrylamide gels are composed of a mix of polyacrylamide and bis-acrylamide, which form a crosslinked polymer by the polymerizing agent ammonium persulfate (APS) and the catalyst TEMED (N,N,N,N´-tetramethylenediamine).
- What is non-denaturing polyacrylamide gel electrophoresis (native PAGE)?
- Non-denaturing polyacrylamide gel electrophoresis (Native PAGE) is the polyacrylamide gel electrophoresis of proteins without the addition of denaturants such as SDS.
