Phosphate Buffered Saline 3ml Australia | Research Supplies
Phosphate buffered saline is a sterile, isotonic salt solution buffered to a stable pH of around 7.4. It is one of the most widely used solutions in laboratory research, valued for being gentle, non-reactive and free of preservatives.
It is the reconstitution solution commonly specified for ARA-290, and is now available from local Australian stock.
What Is Phosphate Buffered Saline?
Phosphate buffered saline is a water-based solution of sodium chloride and phosphate salts. The phosphate buffer keeps the pH stable, and its salt balance closely matches physiological conditions, which is why it is a standard solution across biology and peptide research.
Phosphate Buffered Saline vs Bacteriostatic Water
Unlike bacteriostatic water, phosphate buffered saline contains no benzyl alcohol or other preservative. Some research compounds are specified for reconstitution with phosphate buffered saline rather than bacteriostatic water, most notably ARA-290. It is also suited to compounds where a preservative-free, pH-neutral solution is preferred. Always check the documentation for the compound you are working with.
