Ionic buffer

WebSodium dihydrogen phosphate – disodium hydrogen phosphate – This buffer has a pH range between 5.8 and 8.0 and is usually used when the researcher needs to completely solubilize and denature the target proteins. NP-40 – This non-ionic buffer solution is widely used for analyzing cytoplasmic or membrane-bound proteins and whole cell extracts. 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 ...
