【Product Description】

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.

The function of a salt solution is:

To maintain the medium within physiological pH range.

To maintain intracellular and extra cellularosmotic balance.

Modified with a carbohydrate, such as glucose serves as an energy source.

It is most commonly used for tissue disaggregation and monolayer dispersal since presence of Calcium and Magnesium ions may hinder the trypsinactivity. It is also used for routine immunohistochemical testing and as a general

purpose solution for washing cells in various haematological and mol ecular biology procedures.
