Ph of stacking gel
WebIn stacking gel with pH 6.8, the N-terminal amino group of the proteins and amino acids are protonated at equilibrium which makes them less negative. The average electrophoretic … 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).
