WebThe ionic buffer keeps the pH within a narrow range and provides a reservoir of weak acid and base. It helps with keeping the electrical flow through the gel which results in keeping an appropriate medium in the gel. Electric voltage makes it possible for the protein to migrate from the positive pol to the negative. WebThere are a couple of rules of thumb to follow: #1. For best results, use a buffer that has a pH at least 2 units away from the pKa for the analyte of interest. If the pH of the mobile phase is too close to the analyte’s pKa, you might observe split peaks or shoulders. If your analyte is acidic, then selecting a pH below its pKa results in ...
