PBS (phosphate buffered solution)
PBS (Phosphate-Buffered Saline)
Laboratory Buffer for Research & Biological Applications
PBS (Phosphate-Buffered Saline) is a water-based, isotonic buffer solution widely used in biological and biochemical research. It is formulated with phosphate salts and sodium chloride to maintain a relatively stable pH and osmotic environment during laboratory procedures.
Because of its compatibility with many biological materials, PBS is commonly used for sample preparation, washing, dilution, and cell- and protein-related research workflows.
Function & Purpose
PBS provides a controlled aqueous environment that helps maintain pH and ionic balance during laboratory procedures. Unlike bacteriostatic water, PBS is primarily a buffering and washing solution, rather than a preservative-containing diluent.
Its composition can vary by formulation, including differences in phosphate concentration, sodium chloride concentration, pH, and the presence or absence of calcium and magnesium.
Research Applications
PBS is commonly used in laboratory environments for:
Washing cells, tissues, and laboratory samples
Diluting biological samples and research reagents
Preparing samples for biochemical analysis
Maintaining controlled pH conditions during experiments
Protein, cell biology, and molecular biology research
