What Is Phosphate Buffered Saline?
Phosphate buffered saline is a water-based salt solution containing sodium chloride, disodium hydrogen phosphate, and potassium phosphate. Its balanced composition makes it one of the most widely used buffer solutions available. PBS maintains a stable pH of 7.4, which is critical where pH consistency matters.
