Description

Background

Williams′ Medium E is a modification version of Williams′ Medium D by Williams and Gunn. Although, it is like MEM, but there is difference in glucose as well as amino acid contents.  This media was originally used to isolate and culture primary liver epithelial cells from Epithelial-like cells of fibroblast-like cells culture. It has been shown that this medium is suited for longer term adult primary cell culture.

PurMa™ William’s E Medium is

  • Suited for long term culture.
  • Enriched in amino acids.
  • Double the glucose compared to the original formulation.
  • Moreover, contains unique ingredients, including zinc, iron, manganese, non-essential amino acids, the reducing agent glutathione as well as lipid methyl linoleate

Moreover, PurMa™ William’s E Medium also contains:

  • Low level of glucose (2.00 g/ liter). PurMa Biologics manufacturers the high glucose (4.5 g/L) version of this media as well (Cat #: P3S029880)
  • Although the standard formulation contains 2.2 g/L Sodium bicarbonate, but PurMa Biologics manufacturers the high sodium bicarbonate (3.7 g/L) Williams′ Medium E as well (Cat #: P3S032880)
  • 2 mM L-glutamine (292 mg/L)’

PurMa Biologics manufactures 112 types of William’s E Medium which is certainly the most comprehensive catalog of media.

    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.
