| MgCl2 x 6 H2O | 3 mM | 203.30 g/mol | 609.90 mg |
| HEPES | 20 mM | 238.31 g/mol | 4 766.2 mg |
| KCl | 130 mM | 74.56 g/mol | 9 692.8 mg |
| KH2PO4 | 10 mM | 136.09 g/mol | 1 360.9 mg |

Preparation without BSA
- Weigh all ingredients (besides BSA) according to the table above and transfer them into a big glass beaker.
- Add about 750 mL H2O.
- Under stirring adjust the temperature to 25 °C.
- Adjust the pH to 7.12 with 5 M KOH.
- Adjust final volume to 1 L and divide in 40 mL portions.
- Store at -20 °C.
