PBS (Phosphate Buffered Saline) (1X, pH ) preparation guide and recipe. Recipe can be automatically scaled by entering desired final volume. PBS is an isotonic buffer frequently used in biological applications, such as washing cells, transportation of tissues, and dilutions. PBS closely mimics the pH, osmolarity, and ion concentrations of the human body.
Calcium Phosphate is the calcium salt of phosphoric acid with widely used applications. This agent can be used as a countermeasure for exposure to strontium and radium radionuclides. Upon oral uptake, calcium phosphate competes for and blocks the absorption of radium (Ra226) and strontium in the gastrointestinal (GI) tract.
