Phosphate buffered saline (PBS) is a buffer solution containing sodium chloride, sodium phosphate, and potassium phosphate. PBS helps to maintain a constant pH and is isotonic and non-toxic to cells. For this reason, PBS is used for a variety of cell culture applications, such as washing cells before dissociation, transporting cells or tissue, diluting cells for counting, and preparing reagents.
PBS is formulated without calcium and magnesium.
All buffered salt solutions are shipped via FedEx Ground unless ordered with other media or otherwise requested. Shipping charges vary by weight.
