TGS 10X Solution (Tris Glycine SDS Buffer) is commonly used in protein electrophoresis, specifically in SDS-PAGE for separating proteins based on their molecular weight. This 1-liter bottle contains a concentrated buffer that helps maintain the pH and the ionic strength during the electrophoresis process. The SDS (sodium dodecyl sulfate) is a detergent that denatures proteins, ensuring they are separated purely by size rather than charge. TGS buffer is an essential reagent in protein analysis and is used in a variety of applications, including protein quantification, purification, and molecular weight determination.
