WebThe article provides an overview of common methods used to remove contaminants from protein lysates and techniques for concentrating protein samples. Overview of dialysis, desalting, buffer exchange and protein concentration Thermo Fisher Scientific - US WebProtein precipitation during dialysis against phosphate or Tris buffers (PBS or TBS) can be often caused by: Too low salt concentration (NaCl, KCl) Too high protein concentration Sudden pH changes pH of dialysis buffer close to PI of a protein Therefore: Use at least 1000-fold excess of dialysis buffer raymond kirby obituary
