FluxMPS™ Dulbecco’s Modified Eagle Medium (DMEM), High Glucose: 1X Liquid

FluxMPS™ DMEM High Glucose with Folic Acid — MPS-Grade 1X Liquid Cell Culture Medium

FluxMPS™ DCP-DMEMHGFA1X is an MPS-grade, quadruple-stage ultra-filtered Dulbecco’s Modified Eagle Medium formulated with 4,500 mg/L glucose, L-glutamine, sodium pyruvate, sodium bicarbonate, phenol red, and folic acid — engineered for microfluidic channels, organ-on-a-chip (OoC), and microphysiological systems (MPS) where particulate contamination corrupts biosensor signals and blocks micron-scale conduits. Filtered through a proprietary 0.1 µm ×2 + 0.04 µm ×2 cascade, this medium delivers approximately 5× lower subvisible-particulate burden than conventional 0.22 µm-filtered DMEM — making it the purest ready-to-use high-glucose DMEM with folic acid available for chip-based biology.^[1,2]

• Quadruple-stage nano-filtration: 0.1 µm (pre-filter I) → 0.04 µm (pre-filter II) → 0.1 µm (sterile I) → 0.04 µm (final polish) — sub-mycoplasma polishing at every stage
• Ultra-low particulate, microchannel-safe: USP <788> Method 2 compliant; approximately 5× cleaner than conventional 0.22 µm filtered media by particulate count
• Endotoxin < 0.05 EU/mL (USP <85> BET) — protects cytokine-sensitive organ-chip models from inflammatory noise
• Full-nutrient high-glucose DMEM: 4,500 mg/L D-Glucose, 584 mg/L L-Glutamine, 110 mg/L Sodium Pyruvate, 3,700 mg/L NaHCO₃, and folic acid (4 mg/L) for folate-pathway-sensitive cell lines
• Prepared with Ultrapure Type 1 water (18.2 MΩ·cm); 4× BME amino acid and vitamin concentration per DMEM specification
• ISO Class 5 (Class 100) aseptic fill & finish — ISO 13485:2016 QMS, 21 CFR Part 820 (cGMP) aligned
• Customizable formulation: pH, glucose concentration, salts, HEPES, and nutrient composition available on request — contact support@diagnocine.com

Engineered where standard DMEM fails

Conventional 0.22 µm-filtered DMEM leaves behind subvisible particulates, mycoplasma-sized debris (0.1–0.3 µm), and endotoxin fragments that are invisible to the eye but catastrophic inside microfluidic channels whose widths can measure as little as 10–100 µm. These contaminants accumulate at chip inlets, corrupt TEER and electrochemical biosensor baselines, trigger sterile inflammation in cytokine-sensitive organ models, and block gravity-fed perfusion. FluxMPS™ DCP-DMEMHGFA1X eliminates all of these failure modes through a four-stage nano-filtration cascade that no single-stage membrane can replicate.^[3,4]

Quadruple-stage filtration system

DCP-DMEMHGFA1X is the only ready-to-use high-glucose DMEM with folic acid filtered through a four-stage 0.1 µm ×2 + 0.04 µm ×2 cascade — achieving sub-mycoplasma polishing levels that no single 0.22 µm membrane can approach. Each stage is independently validated before aseptic ISO Class 5 fill.

1. 1

   0.1 µm Pre-filtration I — Large Particulate Removal

   The first 0.1 µm membrane captures macro-aggregates, undissolved powder residues, and large particulate matter generated during formulation. Removing this bulk load at stage 1 dramatically extends the service life and efficiency of all downstream membranes.

2. 2

   0.04 µm Pre-filtration II — Fine Particulate & Mycoplasma Retention

   The first 0.04 µm (40 nm) stage captures fine particulates, bacteria, and mycoplasma-sized contaminants (100–300 nm), delivering a sub-mycoplasma polished stream before sterile-filtration stages begin. This is the stage that separates MPS-grade media from conventional offerings.

3. 3

   0.1 µm Sterile-filtration I — Redundancy Pass

   A second independent 0.1 µm sterile-filtration membrane provides validated redundancy against bacterial breakthrough, as required for pharmaceutical-grade sterility assurance. This pass is documented in the batch manufacturing record for every lot.

4. 4

   0.04 µm Sterile-filtration II — Final Polish & ISO Class 5 Fill

   The ultimate 40 nm polish stage is immediately followed by ISO Class 5 (Class 100) aseptic fill under laminar flow. The medium reaches the bottle at its cleanest possible state, with particulate burden verified by USP <788> Method 2 light-obscuration prior to release.

Designed for next-generation cell culture platforms

DCP-DMEMHGFA1X supports the full spectrum of advanced mammalian cell culture — from classical monolayer experiments to perfused microphysiological systems. Its MPS-grade purity is especially critical for models requiring optical clarity, biosensor precision, and contamination-free multi-week perfusion runs. Folic acid inclusion supports applications demanding active folate-pathway metabolism, one-carbon cycle studies, and proliferating epithelia on-chip.^[7,8]

Automated Bioreactors & Robotics

For fully automated perfusion bioreactors and robotic liquid-handling platforms, an optional 0.01 µm (10 nm) ultra-filtered variant of DCP-DMEMHGFA1X is available on inquiry. At this pore size, essentially all subvisible particulate matter, protein aggregates, and nanoscale debris are excluded — protecting precision valves, microfluidic sensors, and automated sampling probes from clogging or signal drift across extended culture runs.

• Total Particulate Exclusion: 10 nm filtration removes virtually all subvisible debris, protecting micro-valves and pneumatic actuators in automated systems
• Valve & Sensor Protection: Near-zero particulate burden prevents valve seat fouling and optical sensor drift in closed-loop bioreactor perfusion circuits
• Extended Perfusion Stability: Cleaner medium reduces fouling of perfusion tubing and inline sampling ports, supporting uninterrupted multi-week automated culture runs

Inquiry Required: The 0.01 µm (10 nm) ultra-filtered grade is a custom variant produced on request for automated bioreactor and robotic platform applications. Contact support@diagnocine.com to request this grade.
