Phosphate buffer is an important buffer that we use in biochemistry laboratories. It is often used to extract and isolate proteins and enzymes that have optimal pH of around 7. That is because the buffering capacity of a phosphate buffer is pH 7.21 ± 1 within which most of the proteins and enzymes are more stable.
