Spinner Salts, Eagle w/ Phenol red w/o Calcium chloride and Sodium bicarbonate

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 Tyrode's solution. Since then many modifications have been done to obtain better buffering salt solutions and to prevent calcium precipitation. 1X powdered Spinner Salts, Eagle is with Phenol red. It does not containt Calcium chloride and Sodium bicarbonate.
