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.
WebNov 30, 2024 · Two Options to Make the Buffer. There are two methods of making sodium citrate buffers, depending on the materials accessible to you. If you have both citric acid and the conjugate base, create a stock solution of each by mixing 21 grams of citric acid in 1 liter of distilled water, and 29.4 grams of sodium citrate in 1 liter of distilled water. WebApr 12, 2016 · Within the normal pH range, citrate has an acid-dissociation constant (pK a) value at 4.8 and 6.4, and phosphate has a pK a at 6.8. The mixture of the two buffering salts allows us to control pH well in the range of 4–8. Because all these formulations have the same buffer composition, the effect of buffer types on MAb stability is eliminated.
