General description

Phosphate buffered saline or PBS, pH 7.4 is a commonly used biological buffer in molecular biology. A 1X working solution is typically used in cell culture and electrophoresis assays to wash away non-adherent cells or any unbound biomolecules. PBS is hypo-osmotic and can be harmful to cells, causing swelling and resulting in cell lysis, if left for extended periods.

Application

Phosphate buffered saline is commonly used in washing solutions for:
  • ELISA
  • Western Blotting and other protein applications
  • Cell culture (sterile filtration recommended)
  • Resuspension and sonication of cells
  • Immunohistochemistry

Features and Benefits

  • Save time with our ready-to-use formulation
  • No calculations, measurements, and adjusting pH
  • Reliable quality for reproducibility
  • Suitable for use in cell culture and electrophoresis
  • Biological tests: free of DNase, RNase, Protease, and Nickase
  • Chemical tests: Iron ≤10 ppm, Lead ≤5 ppm

Packaging

Foil pouches

Reconstitution

Contents of one pouch, when dissolved in 500mL of distilled or deionized water, will yield a 1X solution containing 10mM Na2HPO4, 1.8mM KH2PO4, 138mM NaCl, 2.7mM KCl, pH 7.4 at 25 °C. Certified to be DNAse, RNAse, Protease, and Nickase free. Certified for use in cell culture.
