Advanced Leibovitz’s L-15 Medium

(18 customer reviews)

Advanced Leibovitz’s L-15 Medium contains L-Alanyl-L-Glutamine as well as ingredients to allow for serum reduction. Furthermore, Advanced Leibovitz’s L-15 needs 2-5% FBS and additionally provides more consistency.

Description

Background

PurMaTM Advanced Leibovitz’s L-15 Medium contains components that allow for a 60–90% reduction in FBS supplementation. More importantly, using synthetic components such as recombinant insulin, albumin, and transferrin increases consistency. This results in less variation amongst lot-to-lot serum changes. In A-Leibovitz’s L-15, L-Alanyl-L-Glutamine is used as the source of glutamine. Additionally, reducing FBS requirements lowers the cost of cell culture experiments.

Contents

Advanced Leibovitz’s L-15 Contains:

  • includes all twenty essential and non-essential amino acids with higher concentrations than regular and MAX formulations.
  • incorporates elements that significantly reduce the need for a serum for cell culture.

Crucial Ingredients:

  • PurMaTM Human Transferrin (Holo): prevents Improper iron storage and delivery in cell culture systems which is a major contributor to oxidative stress and protein damage.
  • PurMaTM Insulin Recombinant
  • Trace of other elements which mimic the elements in fetal bovine serum.

Consequently, Advanced Leibovitz’s L-15 Medium is a significant step toward a chemically defined form of this media. Unquestionably, Chemically Defined Advanced Leibovitz’s L-15 (CD-A-Leibovitz’s L-15) is the outcome of decades of cutting-edge research and will soon be offered globally to laboratories that are looking for consistency and repeatability in their data.

    Review: I have worked directly with PurMa biologics on a number of projects ongoing in my lab. I find the media and the specialty Lipid Depleted Serum to be high quality and very consistent among batches, which is critical to our adipogenesis projects using primary stem cells. Also, the service from PurMa is outstanding for my lab.

    Review: I started my lab using the regular Gibco media components. We have shifted to Purma past 6 months and see no difference in the quality of our cell culture. Simply saying that Purma is cheaper, quicker to deliver and as good as Gibco. The best part was that Purma customized several media for our fish cell lines which was really helpful. Lastly, Seif walked through the customization of media over Zoom, that gave a lot of confidence for using those media solutions.

    Review: Reliable and dependable products. We purchased lipid-depleted FBS (LD-FBS) from PurMa Biologics and it worked great. We cross-checked the lipid content in the serum by GC-MS and Triglyceride assay and as advertised, did not find any lipids in the FBS.
