Dulbecco's PBS (DPBS) or Phosphate-buffered Saline (PBS) is a buffer solution used in numerous biological applications, such as for maintaining pH, diluting substances, or rinsing of cell containers. It maintains the milieu in a viable physiological range to sustain cells.
DPBS is non-toxic and provides cells with water and inorganic ions necessary for cell metabolism. The osmolarity and ion concentrations of PBS solution is meant to mimic the isotonic milieu of the human body. This powdered formulation of DPBS comes in a 1X concentration without Ca & Mg and Phenol Red. The concentration of the powdered buffer solution is 1X.
Phosphate-buffered saline powder provides a convenient way to make large volumes of standard 1X Phosphate Buffer for cell culture. The dry powdered cell culture media and buffers are manufactured using the highest quality ingredients. This powder is precisely blended using clean, controlled, state-of-the-art equipment to eliminate contaminating dust and to control the temperature and humidity.
