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). WebAt the same time, the separating part of the gel also has a pH value in which the buffer ions on average carry a greater charge, causing them to "outrun" the SDS-covered proteins and eliminate the ion gradient and thereby the stacking effect.
