PBS (Phosphate Buffered Saline)
Buffer and diluent
Phosphate-buffered saline is an isotonic, pH 7.4 salt solution used throughout laboratories as a sterile diluent and buffer. It holds samples at a stable, physiological pH and salt concentration. It is a laboratory reagent, not a research compound.
Also known as Phosphate-buffered saline
How it is studied
The phosphate buffer resists pH shifts and the saline matches biological osmolarity, making PBS a neutral medium for handling samples.
Research context
Used as a diluent and wash buffer in laboratory research.
