WebSDS sample buffers or loading buffers Protein samples prepared for SDS-PAGE analysis are denatured by heating in the presence of a sample buffer containing 1–2% SDS or LDS with or without a reducing agent such as 20 mM DTT, 2-mercaptoethanol (BME) or TCEP. WebLaemmli-SDS-PAGE system is discontinuous buffer system. Different PH (and ionic strength) in stacking gel and separating gel can help protein samples concentrate/stack in stacking gel before running in a separating gel.
