Buy Phosphate Buffered Saline 99.9% Pure at Peptalynlabs.com — USA Research Supply
Peptalynlabs.com supplies Phosphate Buffered Saline at 99.9% purity to researchers, resellers, and distributors across the United States and Europe. Phosphate Buffered Saline, commonly known as PBS, is a water-based salt solution. Researchers use it as a diluent, wash buffer, and reconstitution vehicle across virtually every area of biological and biochemical research.
PBS maintains a stable pH of 7.4 in research models. This matches the physiological pH of human blood and tissue. It is one of the most widely used buffer solutions in laboratory research worldwide. Every order ships with a Certificate of Analysis confirming 99.9% purity.
Phosphate Buffered Saline
What Is Phosphate Buffered Saline
Phosphate Buffered Saline is a balanced salt solution containing sodium chloride, sodium phosphate, and potassium phosphate. Some formulations also include potassium chloride. Researchers use it because it is isotonic, non-toxic to cells, and maintains a stable physiological pH. You can read a general scientific overview of PBS on Wikipedia.
Researchers use PBS in cell culture washing, tissue preparation, protein dilution, peptide reconstitution, flow cytometry, immunohistochemistry, ELISA assays, and drug delivery research. Its simple composition and broad compatibility with biological materials make it the default buffer solution across most laboratory research settings.
PBS Composition and Research Background
Standard 1x PBS at pH 7.4 contains sodium chloride, disodium hydrogen phosphate, potassium chloride, and potassium dihydrogen phosphate dissolved in water. Researchers adjust the ratio of monobasic and dibasic phosphate salts to set the final pH.
10x PBS is a concentrated stock solution. Researchers dilute it to 1x working concentration before use. Dulbecco's PBS, also known as DPBS, is a formulation developed by Renato Dulbecco. It omits calcium and magnesium ions. Researchers use DPBS when calcium and magnesium-free conditions are required, particularly in cell dissociation and washing protocols. PBS with Tween 20, also known as PBST, adds a non-ionic detergent to reduce non-specific binding in washing steps for Western blot and ELISA research.
PBS Research Administration and Laboratory Uses
Researchers use PBS across multiple laboratory applications. It serves as a wash buffer in cell culture to remove media, serum, and debris before passaging or fixing cells. It serves as a diluent for antibodies, proteins, peptides, and other biological compounds in assay preparation. It serves as a reconstitution vehicle for lyophilized research compounds including peptides.
Peptalynlabs.com supplies PBS at 99.9% purity in powder form. Researchers reconstitute it with distilled or deionized water according to their protocol requirements. This allows researchers to prepare 1x or custom concentration solutions on demand.

Search volume grows consistently across terms including phosphate buffered saline, PBS, Dulbecco's phosphate buffered saline, 10x phosphate buffered saline, phosphate buffered saline pH 7.4, and phosphate buffered saline powder across USA and European research markets.
Best Research Compounds to Consider Alongside PBS
Researchers sourcing PBS frequently purchase it alongside peptide and protein research compounds that require reconstitution. Any lyophilized peptide on Peptalynlabs.com, including BPC-157, GHK-Cu, TB-500, and IGF-1 LR3, requires a reconstitution vehicle. PBS is one of the most commonly used vehicles in published peptide research protocols. Resellers who stock PBS alongside their peptide catalog give research buyers a complete sourcing solution from one supplier.
What to Consider Before Starting a Research Supply Reselling Business
Before sourcing PBS or any research compound for resale, new resellers should address the following:
- Confirm your jurisdiction's regulations on research compound distribution
- Source only from suppliers who include a Certificate of Analysis on every order
- Build a compliant storefront with research-use-only disclaimers before listing products
- Identify your target buyer, whether individual researchers, cell biology research groups, or laboratory procurement teams
- Start at low volume and scale as demand confirms itself
- Know customs requirements for research compound imports in your target markets
Why Buy PBS Online From Peptalynlabs.com in 2026
