Description

Background

PurMa Biologics manufactures PurMa™ Charcoal-Stripped Fetal Horse Serum (CS-FHS) by treating the Fetal Horse Serum with activated carbon is an effective process for removing hormones and steroids.

  • This process removes all the non-polar material such as lipophilic (lipid-related) materials (virus, certain growth factors, hormones, and cytokines).
  • It is an effective blocker agent in immunoassay systems as well as immunoprecipitating analysis (by coating the Sepharose-activated beads to prevent nonspecific binding).
  • Regardless of the molecular weight of the target.

PurMa Biologics applies Norit A charcoal coated with Dextran T-70 manufactures a high-quality Charcoal-Stripped Fetal Horse Serum.

PurMa™ Charcoal-Stripped FHS (DFHS)

  • PurMaTM Premium FHS is USA origin.
  • The parent FHS has been gamma irradiated.
  • Following the stripping, the FHS goes through heat inactivation process.
  • Following the stripping, the FHS goes through vigorous analysis and will get a certificate of analysis.
  • It is free of mycoplasma, steroids and hormones, and other pathogens.
  • Acceptable level of endotoxin (10 mg/Dl) and hemoglobin (20 mg/Dl).
  • Due to the loss of a vast variety of hormones and steroids (such as growth factors), we recommend using 15-20% CS-FBS in your media to make sure cultured cells are well beings.

    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.
