Separating Protein: SDS-Polyacrylamide Gel Electrophoresis (SDS-PAGE) | Protocol
Overview. Sodium Dodecyl Sulfate Poly-Acrylamide Gel Electrophoresis, or SDS-PAGE, is a widely-used technique for separating mixtures of proteins based on their size and nothing else. SDS, an anionic detergent, is used to produce an even charge
Gel electrophoresis separates DNA fragments by size in a solid support medium (an agarose gel). DNA samples are pipetted into the sample wells, seen as dark slots at the top of the picture. Application of an electric current at the top DNA

GelRed® can also be used to stain polyacrylamide gels via post gel staining. GelRed® is also compatible with downstream DNA manipulations such as restriction digest, sequencing, and cloning. GelRed® and EtBr have virtually the same spectra, so
- What is cationic polyacrylamide?
- Cationic Polyacrylamide is white power or granule, the degree of ion is from 5% to 80%, soluble, good water solubility, can be dissolved in water at any percentage and be undissolved in organic solvents. CPAM shows characteristics of high polymer electrolyte, suitable for wastewater treatment with a negative charge and rich organic matter.
