Tris-Glycine SDS Running Buffer (10X) is used as the electrophoresis buffer during the stacking and resolve process of sodium dodecyl sulfate - polyacrylamide gel electrophoresis (SDS-PAGE). It is ideally suited for protein gel analysis in biochemical, molecular biological, cell biological,and immunological research studies.

WebbOnce the protein reaches the resolving gel, the pH changes from 6.8 to 8.8 and the pores are smaller. As pH increases, the N-terminal amino groups are deprotonated. Amino acids and proteins are more negatively charged at equilibrium than in stacking gel. As a result, glycine moves faster than proteins.
