Significant Differences between SDS PAGE and Native PAGE
Sodium-dodecyl sulfate (SDS) PAGE and Native PAGE are two types of gel techniques where denature and non-denatured gels, respectively, are used for separation. SDS PAGE. Sodium-dodecyl sulfate polyacrylamide gel electrophoresis is a technique used to separate protein molecules of masses 5 to 250 kDa. The proteins are separated solely on the ...

1.15: SDS-PAGE
Sodium dodecyl sulfate (SDS) is an amphipathic detergent. It has an anionic head group and a lipophilic tail. It binds non-covalently to proteins, where roughly one SDS molecule is attracted to every two amino acids. SDS causes proteins to denature and disassociate from each other (excluding covalent cross-linking) and essentially …
