Advanced Leibovitz’s L-15

PurMaTM Advanced Leibovitz’s L-15 contains components that allow for a 60–90% reduction in FBS supplementation. Using synthetic components such as insulin recombinant full chain, recombinant albumin, and transferrin increase consistency in results with less variation amongst lot-to-lot serum changes.  In Advanced Leibovitz’s L-15, L‑alanine‑L‑glutamine is used as the source of glutamine.  Additionally, reducing FBS requirements lowers the cost of cell culture experiments. Advanced Leibovitz’s L-15 contains:

  • All the twenty essential and non-essential amino acids with higher concentrations than regular and MAX formulations.
  • It includes the elements which significantly reduce the need for a serum for cell culture including:

Advanced Leibovitz’s L-15 is a substantial upgrade to the standard and MAX for of Leibovitz’s L-15. That is because media this media contains ingredients to allow for serum reduction, specifically: ethanolamine, glutathione, ascorbic acid, insulin, transferrin, lipid rich PurMaTM Albumin, trace elements such as sodium selenite, ammonium metavanadate, cupric sulfate, and manganous chloride.

  1. PurMaTM Albumin:  Chromatographically purified with IgG content <=0.1.0%.
  1. PurMaTM Human Transferrin (Holo): prevents Improperly iron storage and delivery in cell culture systems which is a major contributor to oxidative stress and protein damage.
  2. PurMaTM Insulin Recombinant
  3. Trace of other elements which mimic the elements in fetal bovine serum.

In another word, the advanced form of Leibovitz’s L-15 is a significant step toward chemically defined form of this media where all elements are synthetic and the need for FBS is eliminated.

Chemically Defined Leibovitz’s L-15 (CD- Leibovitz’s L-15) is the next generation of PurMa Biologics’ dedicated team of top scientists which is the outcome of decades of cutting-edge research. CD- Leibovitz’s L-15 soon will be offered globally to laboratories who are looking for consistency and repeatability among their data.
