Does anyone know about the pH of the stacking gel in SDS-PAGE?

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). WebMar 22, 2024 · The buffer used in the running gel is Tris.Cl at pH 8.8. Stacking gel: The stacking gel is layered on top of the separating gel after it has polymerized completely. It is prepared using 2-5% of acrylamide and is consequently highly porous and devoid of any molecular sieving action.
