L-15 Medium (Leibovitz)

CAD 22.00

L-15 Medium (Leibovitz) was originally formulated for use in carbon dioxide free systems requiring sodium bicarbonate supplementation.  L-15 is buffered by its complement of salts, free base amino acids, higher levels of galactose (in place of glucose) and sodium pyruvate to help maintain physiological pH control. Many viruses have been successfully cultivated in this medium. This media has been shown to work for human tumor cells as well as primary explants of embryonic and adult human tissue. When properly supplemented, Leibovitz L-15 Medium supports established cell lines, such as HEp-2, L929, MRC-5, and LLC-MK2. Many viruses have also been successfully cultivated in this medium.
