Leibovitz’s L-15 Medium was formulated for use in a carbon dioxide (CO2) free environment. It contains no sodium bicarbonate, and is buffered by phosphates, free base amino acids, and galactose instead. L-15 (Leibovitz) supports the proliferation of many established cell lines and primary cells. Atlanta Biologicals offers a selection of L-15 modifications, including versions with HEPES buffer for a more effective buffering capacity.

Leibovitz’s L-15 Medium

L-15 requires supplementation with serum, typically 10% Fetal Bovine Serum (FBS), since this medium does not contain proteins, lipids, or growth factors.
