Cell Culture Buffers
Tissue culture buffers provide an energy source, maintain proper pH levels, and keep ideal osmotic pressure present. Used predominately in biomolecular research, the dry and liquid substances have a balanced inorganic salt composition. Lower concentration options permit equilibration with air in a closed system, while higher salt concentration options keep gaseous phases in equilibrium. Cell growth is optimal when plated in a nutritional medium that has been buffered.
EDTA, 0.5M pH 8.0, Corning®
Supplier: Corning
EDTA (ethylenediaminetetraacetic acid) is a polyamino carboxylic acid. It is a colorless, water-soluble solid and is useful as a chelating agent due to its ability to "sequester" metal ions such as Ca2+ and Fe3+. These cations are responsible for various undesirable effects in molecular biological and cell culture processes. After being bound by EDTA, these metal ions remain in the solution but exhibit diminished reactivity. The use of EDTA therefore allows for greater control over many experiments.

10X Phosphate Buffered Saline (PBS), Sterile, Dulbecco's Formula, without Magnesium and Calcium
Supplier: MP Biomedicals
Role of a balanced salt solution in cell culture is multifaceted and can be divided into four principal functions: 1. Serves as an irrigating, transporting and diluting fluid while maintaining intra- and extracellular osmotic balance; 2. Provides cells with water and certain bulk inorganic ions essential for normal cell metabolism; 3. Combined with a carbohydrate, such as glucose, provides the principal energy source for cell metabolism; 4. Provides a buffering system to maintain the medium within the physiological pH range (7.2 - 7.6)
