Description
Background
Leibovitz’s L-15 Medium was originally designed to be used in carbon dioxide (CO2) free systems. Therefore, it does not need sodium bicarbonate to provide the buffering capacity. Instead, phosphates, free base amino acids, salts, and galactose maintain the physiological pH.
This media contains:
- High Level of Sodium pyruvate (5mM)
- Undoubtedly, the absence of Sodium Bicarbonate makes this media unique.
- Basically, the buffering Capacity is maintained by other elements, mainly phosphates.
- And finally Using Galactose instead of glucose makes this media quite different.
Application of Leibovitz’s L-15
- Cryopreservation of cells and tissues such as Xenopus sperm and embryonic cells.
- Establishing human tumor cell lines such as Hep-2 cells.
- As a supplement in sterile cell media for the dissection and isolation of kidney cells.
- As an important media which provides a proper buffering system for culturing of lung cells.
- A valid option for growing fish cells originating from cell lines.
