PBS

Phosphate Buffered Saline (PBS) is an isotonic, non-toxic buffer solution widely used in biological and biochemical research. With a physiological pH range of 7.0 to 7.4, PBS mimics the osmolality and ion concentrations of the human body, providing an ideal environment for maintaining cell viability, protein stability, and sample integrity.

PBS is commonly used for:

Protein purification and sample dilution

Blotting techniques and immunoassays (e.g., ELISA, western blot)

Cell washing and as a transport medium for biological specimens

• Maintains physiological pH and ionic balance
• Non-toxic and gentle on cells, even during extended incubations
• Compatible with a wide range of lab protocols and detection systems

Whether you're working with cell-based assays, protein workflows, or diagnostic tests, PBS provides stable, reproducible conditions for your experimental needs.
