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).

Why do we use Tris solution of two different pH during …

Webhigher, stacking gel is slightly acidic (pH 6.8) and has a lower acrylamide concentration making a porous gel, which separates protein poorly but allows them to form thin, sharply defined bands. The lower gel, called the separating, or resolving gel, is basic (pH 8.8), and has a higher polyacrylamide content, making the gel's pores narrower. WebGenerally we use 1.5M Tris (pH=8.8) for preparation of resolving gel but 1.0M Tris (pH=6.8) for stacking gel.
