PBS 1X Solution (Phosphate-Buffered Saline) is a balanced, isotonic buffer commonly used in biological and biomedical research. Prepared at a working concentration, it contains sodium chloride, sodium phosphate, and potassium phosphate to maintain pH and osmolarity. It is widely used in cell culture, molecular biology, and immunohistochemistry for cell washing, reagent preparation, and sample dilution. PBS helps preserve the integrity and viability of biological samples by providing a stable, non-disruptive environment. Its compatibility with most biological systems makes it a fundamental laboratory reagent.
