FluxMPS™ Dulbecco’s Modified Eagle Medium (DMEM), High Glucose w/o Folic Acid: 1X Liquid
FluxMPS™ Dulbecco’s Modified Eagle Medium (DMEM), High Glucose w/o Folic Acid: 1X Liquid
FluxMPS™ DCP-DMEMWOFA1X is an MPS-grade, ultra-filtered DMEM High Glucose — Folic Acid–Free formulation engineered for specialized research applications where precise formulation control is essential. Processed through a Quadruple-stage filtration system (0.1 µm ×2 + 0.04 µm ×2), it delivers approximately 5× lower particulate counts than conventional 0.22 µm–filtered media. Formulation: [+] High Glucose (4500 mg/L), [+] L-Glutamine, [+] Sodium Pyruvate, [+] Sodium Bicarbonate | [-] Folic Acid.
- Folic acid–free — creates selective pressure for DHFR-mediated gene amplification in CHO-DHFR− cell lines
- Compatible with methotrexate (MTX) step selection for recombinant protein expression amplification
- All other High Glucose DMEM nutrients intact: L-Glutamine, Sodium Pyruvate, Sodium Bicarbonate
- 0.04 µm final nano-filtration — sub-mycoplasma purity for microfluidic channels below 100 µm

Engineered for DHFR selection and folate metabolism research
Standard DMEM High Glucose contains folic acid — a substrate that cells can use to bypass dihydrofolate reductase (DHFR) dependency. Removing folic acid creates the selective pressure needed for DHFR-mediated gene amplification, methotrexate step selection, and any study where folate pathway activity must be controlled. FluxMPS™ delivers this folic acid–free formulation with 0.04 µm filtration and < 0.05 EU/mL endotoxin for use in CHO cell lines and microfluidic bioproduction models.
Microchannel-safe purity
0.04 µm final filtration; USP <788> particulate compliance ensures safe perfusion in every chip geometry, including sub-100 µm channels.
Precise formulation control
Folic Acid–Free — defined omission enabling specific research applications that require exact control of this medium component.
Ultrapure-grade water
Ultrapure Type 1 water (18.2 MΩ·cm), USP <85> — eliminates ionic contaminants that interfere with specialized assays.
Below TLR4 endotoxin threshold
< 0.05 EU/mL endotoxin — prevents LPS-driven inflammatory signaling that would confound specialized cell culture outcomes.
High-glucose energy support
4.5 g/L glucose sustains the energy demands of the cell types and protocols targeted by this formulation.

Quadruple-stage filtration system
Four serial filtration stages reaching a final 0.04 µm polish under ISO Class 5 aseptic conditions — delivering sub-mycoplasma purity unavailable from conventional 0.22 µm filtered media.
-
1
0.1 µm Pre-filtration I — Large Particulate Removal

-
3
0.1 µm Sterile-filtration I — Second-pass Redundancy
Second-pass sterility redundancy; no breakthrough from Stage 1.
-
4
0.04 µm Sterile-filtration II — Final Polish
Ultimate sub-mycoplasma polish; ISO Class 5 aseptic fill & finish.
Performance vs. conventional media
FluxMPS™ DCP-DMEMWOFA1X delivers approximately 5× lower particulate counts than standard 0.22 µm filtered DMEM, with a confirmed mycoplasma barrier at every production stage.
