Phosphate Buffered Saline (PBS) is a non-toxic, isotonic buffer solution with a physiological pH of approximately 7.4, formulated to match the ionic concentration and osmolarity of human body fluids — making it the most widely used diluent, wash solution, and reconstitution vehicle in biological and peptide research. In peptide research protocols, PBS serves as the secondary dilution vehicle for compounds initially reconstituted in acetic acid water or bacteriostatic water, enabling researchers to achieve target working concentrations at physiological pH before experimental application in cell culture, tissue assay, or animal model contexts. Its consistent ionic environment prevents osmotic shock to cell and tissue preparations while maintaining peptide solubility and stability across a broad range of experimental conditions.
