Ph of separating gel
WebRecent advances in buffering technology alleviate this problem by resolving the proteins at a pH well below the pKa of cysteine (e.g., bis-tris, pH 6.5) and include reducing agents (e.g. … WebJul 7, 2024 · Stacking gel has a lower pH (6.8) than the resolving gel (8.8). …. The purpose of stacking gel is to line up all the protein samples loaded on the gel, so that they can enter the resolving gel at the same time. The resolving gel is to separate the proteins based on their molecular weight.
