Why FluxMPS™

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.

FAQ

Frequently asked questions

Common questions about FluxMPS™ DCP-DMEMWOFA1X — DMEM High Glucose Folic Acid–Free.

DCP-DMEMWOFA1X is processed through a Quadruple-stage filtration system reaching 0.04 µm final pore size, delivering ultra-low particulate levels for MPS, OoC, ToC, and LoC platforms. The Folic Acid–Free formulation is delivered with sub-mycoplasma filtration purity and < 0.05 EU/mL endotoxin for specialized cell culture applications on chip.
FluxMPS™ uses four sequential filters — 0.1 µm pre-filtration I, 0.04 µm pre-filtration II (mycoplasma barrier), 0.1 µm sterile-filtration I, and 0.04 µm final polish — resulting in approximately 5× fewer particles and confirmed mycoplasma retention at every production stage.
Folic acid is removed because cells expressing the DHFR (dihydrofolate reductase) transgene can synthesize their own tetrahydrofolate from dihydrofolate — but only if exogenous folic acid is absent. In folic acid–free medium, only cells that have successfully integrated and are expressing DHFR survive. When combined with methotrexate (MTX) treatment, increasing MTX concentrations drive gene amplification to produce more DHFR (and the co-amplified transgene), building up recombinant protein expression level. This is the foundation of CHO-DHFR? selection systems used in biopharmaceutical manufacturing.
5% CO₂ required (sodium bicarbonate buffering).
Yes. Add FBS (typically 5–10%), serum-free supplements, growth factors, antibiotics, or custom nutrients as required. Contact support@diagnocine.com for custom co-formulation.
FluxMPS™ DCP-DMEMWOFA1X is produced to meet < 0.05 EU/mL by LAL assay (USP <85>) on every production lot — 20× below the 1 EU/mL common for cell culture grade reagents.
