Williams Medium E, Powder, With L-Glutamine, Without Sodium Bicarbonate

Isolated epithelial cells, as described in his sequential plating method by Williams, et al., in 1971, were originally cultivated in a rich medium known as Williams' Medium D. From these early newborn animal studies, Williams and Gunn developed a subsequent medium, Williams' Medium E, for the long-term cultivation of adult rat liver epithelial cells.

ITS Premix Solution

ITS Premix will stimulate cell proliferation while decreasing substantially the serum requirements for culture of many cell types as diverse, for example, as contractile rat heart cells and human colon mucosal epithelial cells. Basal media supplemented with ITS Premix and as little as 2% Fetal Bovine Serum support proliferation of many diploid and heteroploid cell lines at rates equivalent to those obtained with 10% serum. Contains 0.5 mg/ml insulin from bovine pancreas, 0.5 mg/ml human transferrin (substantially iron-free) and 0.5 ug/ml sodium selenite. Prepared in Earle's balanced Salt Solution (EBSS) without phenol red. Sterile-filtered.

100 mM Sodium Pyruvate (11.00 mg/mL)

Sodium pyruvate is used by cells as an easily accessible carbohydrate source. Additionally, it is involved with amino acid metabolism and initiates the Kreb′s cycle. The 100 mM solution should be diluted 1:100 for most cell culture. The use of sodium pyruvate in Wallen fermentation medium to enhance the conversion of oleic acid to 10-ketostearic acid by Bacillus sphaericus has been described. A protocol that uses sodium pyruvate to establish stably transfected human B cell lines has been published. It improves coliform recovery when present in culture medium.

10X Dulbecco's Phosphate Buffered Saline, Without Calcium and Magnesium

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)

MEM Amino Acids (50X Solution) Without L-Glutamine

In many cell culture applications using defined media for the in vitro cultivation of cells, the addition of supplemental nutrients and reagents is required. Additives such as antibiotics, buffers, and stains are frequently used to prevent bacterial contamination, control pH, and visibly monitor media conditions. Other supplements such as amino acids and vitamins are useful for enriched media beyond their normal concentrations. Attachment factors and transport factors are added to growth media to facilitate rapid cell propagation and enhance proper cell metabolism. Still other media supplements may be added to create conditions which will elicit specific cellular responses and effects, such as altered protein biosynthesis, accelerated antibody production and secretion, toxic response mechanisms, etc. As a result, the availability of a wide variety of media supplements is desirable when designing cell culture experiments.

Mccoy's 5A Medium (Park & Terasaki Modification) (1X Solution) Without L-Glutamine, Sodium Bicarbonate

McCoy's 5A medium, as modified by Iwakata and Grace, is identical to RPMI 1629. Originally in 1959, McCoy and his colleagues described the amino acid requirements for the in vitro culturing of Novikoff Hepatoma cells. Basal Medium 5A was modified to create what is known as McCoy's 5A Medium for these investigations. Hsu and Kellogg further demonstrated the use of this medium to support the growth of primary cultures derived from normal bone marrow, testes, mouse kidney, skin, gingiva, rat embryo and other tissues. MP's medium is additionally suited for the propagation of leukocytes, biopsy tissues and the most demanding primary and continuous cell types. It is also available as modified by Park and Terasaki.
