Description

Background

PurMa™ Chemically Defined Eagle’s Minimal Essential Medium (CD-EMEM) is a proprietary formulated used to grow cells in vitro without any undefined or animal-derived components. Moreover, CD-EMEM contains known quantities of pure chemicals, including amino acids, vitamins, salts, sugars, and more importantly a proprietary combination of synthetic growth factors.

It is absolutely crucial to mention that the PurMa™ Growth Supplement for each conventional media such a DMEM, IMDM, RPMI-1640… (Base Media ) are slightly different in combination, amount of several growth factors, ions, chemicals,  pH with particular adjustments needs to be done, based on the environments which base media provides.

This provides a consistent and controlled environment for cell growth and research. Noticeably, CD-EMEN is essential for applications that require reproducibility and regulatory compliance as well as for studying specific cellular processes. without extraneous variables. Furthermore, CD-EMEM is designed for custom formulations tailored for various cell types.

The Graph of Chemically defined EMEM

Important Notes:

It is crucially vital for a graduate transition from media containing FBS to chemically defined cell culture media, follow these steps:

  • Starting Point: 10% FBS+ (control) (you need two controls, one to be left in only 10% FBS and continue monitoring for comparing with 0% FBS + PurMaTM Chemically Defined Medium. The second one chemically defined medium + 10% FBS which is going through the reduction of FBS process
  • 48 hours later: 8% FBS in + PurMaTM Chemically Defined Medium
  • 48 hours later: 6% FBS in + PurMaTM Chemically Defined Medium
  • 48 hours later: 4% FBS+ PurMaTM Chemically Defined Medium
  • 48 hours later: 2% FBS+ PurMaTM Chemically Defined Medium
  • 48 hours later: 1 FBS and + PurMaTM Chemically Defined Medium
  • 24 hours later: 0$+% FBS and only PurMaTM Chemically Defined Medium

Importantly, for each change, spin down and fully discard the media and replace it with the less percentages of FBS.

Noticeably, you don’t have to start with a huge number of cells (~500,000 cells/ml). Additionally, we strongly recommend you start with more than one plate as some of the plates might get contaminated

So, once the cells are kept in chemically defined Media, you should always keep them in the same chemically defined medium from the same vendor and the same formulation, even for freezing (see below).

Usually, after you get your cells adopted to PurMaTM Chemically Defined Medium you need to make several plates and freeze down several vials. The mentioned cells are adopted to chemically defined medium and when you thaw them in the first week, in addition to PurMaTM Chemically Defined Medium, you need to add 10% PurMaTM CD Booster (Cat# P3C10144).

Formulation

The CD-EMEM includes a base formulation including L-Alanine -L Glutamine : Base formulation of Chemically Defined EMEM , P3C310110

Additionally, CD-EMEM contains a proprietary synthetic cocktail of specific growth factors, hormones, and other nutrients which makes it independent of any serum and any trace of animal products.

    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.
