Other Notes
ITS is a mixture of recombinant human insulin, human transferrin, and sodium selenite. It is a general cell supplement designed for use in non-complex media (e.g. MEM, RPMI-1640) and complex media (e.g. Ham?s F-12, DME/F-12, MEM) with sodium pyruvate.
Preparation Note
Prepared in Earle′s Balanced Salt Solution (EBSS) without phenol red.
Application
Serum-free and reduced serum formulations often require purified forms of the factors normally supplied by serum that are suitable for in vitro growth and differentiation studies. These important factors include insulin, transferrin, selenium, pyruvate, and ethanolamine.
Nutritional studies indicate that the supplement components described are utilized by most mammalian cells. They enhance cell proliferation and decrease the serum requirement of many cell types. When the provided supplement is used with 2 to 4 percent serum, proliferation is reported to be similar to medium supplemented with 10 percent serum.
