Engineered where standard media fails
Conventional 0.22 µm–filtered DMEM passes mycoplasma-sized organisms, subvisible particulates and cellular debris that clog microfluidic channels and interfere with sensor readouts.[1,2] FluxMPS™ DCP-DMEM-B1X addresses this while supplying 4.5 g/L glucose for energy-demanding cell types cultured without sodium bicarbonate buffering.
Microchannel-safe purity
0.04 µm final filtration; USP <788> Method 1 (light obscuration) particulate compliance supports reliable perfusion in chip geometries down to sub-100 µm channels.
High-energy substrate delivery
4.5 g/L glucose plus L-glutamine and sodium pyruvate sustain energy-demanding cell types — primary neurons, cardiomyocytes and aerobically active cancer lines — in extended perfusion.
Ultrapure-grade water
Ultrapure Type 1 water (18.2 MΩ·cm) with controlled trace-metal and total organic carbon (TOC) content, minimizing extraneous chemical background in the finished medium.
Low background for imaging
Ultra-low particulate baseline supports confocal microscopy and biosensor platforms. This formulation contains phenol red, which contributes to optical background — a phenol-red-free variant is available on request for autofluorescence-sensitive assays.
Rich, stable nutrient profile
32 ingredients verified per lot; 4× Basal Medium Eagle amino acid/vitamin concentration; micro-batch production with full raw-material traceability.
Customization on demand
pH, glucose concentration, salts, HEPES and nutrient composition adjustable. Contact support@diagnocine.com.
Quadruple-stage filtration system
Four serial filtration passes — two dedicated prefilter/final-filter pairs — reaching a final 0.04 µm polish, delivering ultra-low particulate counts for microfluidic channel geometries.
-
1
0.1 µm Prefiltration I
Removes large particulates, cell debris and protein aggregates; protects the first 0.04 µm cartridge from early fouling.
-
2
0.04 µm Final filtration I
First 0.04 µm pass; retains sub-micron particulates and microaggregates that pass a standard 0.22 µm filter.
-
3
0.1 µm Prefiltration II
A second, dedicated prefilter protecting the second 0.04 µm cartridge — not a polish of Stage 2 effluent.
-
4
0.04 µm Final filtration II — Polish
Ultimate polishing filter; aseptic fill & finish under ISO Class 5 (Class 100) conditions.
Performance vs. conventional media
A quadruple-stage train (0.1 µm ×2 + 0.04 µm ×2) reaches a 0.04 µm final cut-off, five times finer than the 0.22 µm membranes used for conventional sterile filtration.
© Diagnocine® — DCP-DMEM-B1X
Designed for next-generation cell models
FluxMPS™ DCP-DMEM-B1X supports demanding platforms from single-channel microfluidic chips to multi-organ body-on-a-chip systems. High glucose (4.5 g/L) without sodium bicarbonate suits energy-intensive, CO2-sensitive culture formats.
Automated Bioreactors & Robotics
An optional 0.01 µm (10 nm) MPS Grade variant of this formulation is available on request for automated bioreactor perfusion and robotic liquid handlers — see the Grade note above for how this differs from the standard Microfluidics Suitable product.
- Total Particulate Exclusion: 0.01 µm filtration removes nanoparticulate aggregates beyond the standard 0.04 µm cut-off
- Valve & Sensor Protection: Reduces micro-fouling risk on solenoid valves and optical sensors
- Extended Perfusion Stability: Consistent high-glucose delivery over weeks-long culture
Inquiry Required: Contact support@diagnocine.com for the 0.01 µm MPS Grade variant.
Organ-on-a-Chip & MPS
Ultra-clean 0.04 µm–filtered media helps prevent microchannel clogging in multi-organ chip architectures.[1,4]
Warburg Effect & Cancer Models
High glucose (4.5 g/L) supports aerobic glycolysis phenotyping in cancer cell lines requiring elevated energy substrates.[3]
Primary Neurons & Brain-on-Chip
High glucose supports the metabolic demands of primary neurons and iPSC-derived neuronal networks in microfluidic perfusion.
Cardiomyocyte & Heart-on-Chip
High-glucose DMEM is used for iPSC-derived cardiomyocyte maturation and heart-on-chip functional assays.
Metabolic Flux Analysis
Defined high-glucose formulation for ¹³C isotope tracing and NMR-based glycolysis/OXPHOS profiling. Not compatible with Agilent Seahorse XF assays, which require bicarbonate-free, phenol red-free medium.
Microscopy & Optical Sensing
Ultra-low particulate filtration supports confocal microscopy and biosensor platforms. This formulation contains phenol red, which contributes background fluorescence; request a phenol-red-free formulation for autofluorescence-sensitive imaging.
