Phosphate Buffered Saline (PBS) is a buffer solution widely used in biological research due to its isotonic and non-toxic nature. With a physiological pH range, PBS mimics the osmolarity and ion concentrations of the human body, making it ideal for applications including protein purification, Western Blotting and immunoassays, sample dilution, and as a transport medium. This buffer is formulated in a 10X concentration, and can be diluted to support its application.
