The composition of PBS is 0.137M NaCl, 0.012M Phosphate, 0.0027M KCl, pH 7.4. Below is the protocol to make 1 litre of 10x concentrate PBS.

Combine the following:

• 80g NaCl
•  2g KCl
•  14.4g Na₂HPO₄ (dibasic anhydrous)
•  2.4g KH₂PO₄ (monobasic anhydrous)
• 800mL distilled H₂O 

1. Adjust pH to 7.4 with HCl
2. Add H₂O to 1L
3. Autoclave for 20 minutes on liquid cycle. Store at room temperature.
