Difference Between Stacking Gel and Separating Gel

WebIn contrast, the stacking gel buffer has a low pH (6.8) and contains Cl-. At the low pH of the stacking gel, the Cl- in the stacking gel are negatively charged and hence move towards the anode (+), but the glycine entering from the gel buffer has only a very small negative charge (pI of glycine ~ 6).
