Frequently asked questions
What is the difference between DPBS and PBS?
Both are isotonic phosphate-buffered salines at about pH 7.4. DPBS follows Dulbecco’s formulation, with slightly less phosphate than standard PBS, and is the version most cell culture protocols specify. For most washing steps they are interchangeable.
Does BZ221 contain calcium and magnesium?
No. BZ221 is calcium- and magnesium-free, which helps cells detach and prevents clumping. DPBS with calcium and magnesium can be made on request.
Is DPBS sterile?
Yes. BZ221 is autoclaved and ready to use. Open and dispense it with aseptic technique.
Can DPBS be used to dilute blood or red blood cells?
Yes. Isotonic DPBS is widely used to dilute whole blood and wash red blood cells in research protocols.
How should DPBS be stored?
Store at 2–30 °C. Unopened bottles have a 1-year shelf life and ship at room temperature.
