Phosphate Buffered Saline KIT (10 VIALS)

Phosphate Buffered Saline (PBS) is a balanced aqueous buffer widely used in biological and laboratory research to maintain a relatively stable pH and provide an isotonic environment compatible with many biological materials.

PBS typically contains sodium chloride, phosphate salts, and water, with formulations varying in concentration and pH depending on the intended application. Its buffering capacity is primarily provided by the phosphate system, while sodium chloride contributes to osmotic balance. Research applications include washing cells and tissues, preparing biological samples, diluting reagents, and supporting immunological, biochemical, and molecular-biology procedures.

Because PBS is generally non-reactive toward many biological components, it serves as a versatile vehicle and experimental buffer rather than functioning as an active pharmacological compound.

Different formulations may additionally contain potassium salts or other components, so the exact composition should always be determined from the specific preparation.

PBS remains one of the most widely used foundational solutions in cell biology and biomedical research because of its reproducible buffering and ionic characteristics.
