What are some common uses of sodium phosphate buffer?

Sodium phosphate buffer is widely used in protein purification, enzyme assays, vaccine formulation, cell lysis protocols, and as a component in diagnostic reagents due to its stable pH and biological compatibility.

Is sodium phosphate buffer the same as PBS?

No, phosphate-buffered saline (PBS) contains sodium phosphate as its buffering agent but also includes sodium chloride and sometimes potassium salts to mimic physiological conditions. While related, PBS is a more complex solution designed specifically for isotonicity and biocompatibility.

Is sodium phosphate buffer suitable for long-term storage of proteins?

Yes, it's often used in protein formulations, especially when combined with stabilizers like glycerol or reducing agents, due to its minimal reactivity and stable buffering.
