Himedia Dulbecco`s Phosphate Buffered Saline w/ Calcium and Magnesium w/o Phenol red

All media used in tissue culture have a basis of a synthetic mixture of inorganic salts known as a physiological or balanced salt solution (BSS). All the physiological salt solutions have been derived from the salt solution originally described by Sydney Ringer (1885). The first balanced salt solution to be developed specifically for supporting the metabolism of mammalian cells was Tyrodes solution. Since then many modifications have been done to obtain better buffering salt solutions and to prevent calcium precipitation. Dulbeccos Phosphate Buffered Saline contains Calcium and Magnesium and is without phenol red.
