FluxMPS™ Dulbecco’s Modified Eagle Medium (DMEM), Low Glucose w/o L-Glutamine, Sodium Pyruvate: 2X Liquid
FluxMPS™ Dulbecco's Modified Eagle Medium (DMEM), Low Glucose w/o L-Glutamine, Sodium Pyruvate: 2X Liquid
Double-strength (2X) DMEM Low Glucose — 2.0 g/L glucose in the concentrate, 1.0 g/L at 1X — for semisolid, colony-formation, 3D and metabolic studies that need a lower-glucose environment, ultra-filtered through a quadruple-stage 0.1 µm / 0.04 µm filtration system. With a sodium bicarbonate buffer, it is approximately 5× cleaner than conventional 0.22 µm-filtered media by particulate count.
- 2X concentrate: mix with an equal volume of a compatible solution or matrix for a final 1X medium
- Quadruple-stage filtration: 0.1 µm membrane filtered twice, 0.04 µm membrane filtered twice

Engineered where standard media fails
Conventional DMEM is sterile-filtered once at 0.22 µm. That pore size can pass mycoplasma and leaves subvisible particulates that settle in microchannels, foul membranes and hydrogels, and add noise to optical readouts.[11,12] FluxMPS™ DMEM keeps Dulbecco's formulation and removes that failure mode.
Microchannel-safe purity
A 0.04 µm final filter and USP <788> particulate control keep subvisible debris out of chips, tubing, membranes and matrices.
Total metabolic control
Defined 2,000 mg/L D-glucose, no L-glutamine and no sodium pyruvate in the 2X (half that at 1X).
Ultrapure-grade water
Made with Ultrapure Type 1 water (18.2 MΩ·cm) and released at < 0.05 EU/mL endotoxin by USP <85>.
Low background for imaging
Particle-depleted medium reduces scatter and debris artifacts in colony counting, confocal imaging and on-chip sensing.
Matrix-ready 2X strength
31 components at double strength, so agar, collagen, hydrogels or treatment solutions can be added 1:1 without diluting the medium below 1X.
Customization on demand

Quadruple-stage filtration system
Every lot of DCP-DMEML-QP2X is membrane filtered at 0.1 µm twice and 0.04 µm twice — a ready-to-dilute 2X DMEM polished to a 0.04 µm final pore size, a purity level single-pass 0.22 µm media cannot reach.

Where FluxMPS™ DMEM fits
DMEM Low Glucose is a widely used basal medium containing 1.0 g/L glucose at its standard 1X working concentration.[1,2] It supports the culture of many primary and established mammalian cells and is commonly used for fibroblast culture, stem-cell research, metabolic studies, tissue engineering, and other applications that require a lower-glucose environment.[3]
DMEM Low Glucose 2X is a double-strength formulation designed to be diluted to 1X or combined with an equal volume of another compatible solution while maintaining the intended final concentrations of glucose, amino acids, vitamins, and salts. The 2X concentrate contains 2.0 g/L glucose and provides 1.0 g/L glucose after a 1:1 dilution.
Researchers may use the 2X formulation when incorporating large volumes of agar, agarose, methylcellulose, collagen, hydrogels, treatment solutions, supplements, or cell suspensions that would otherwise dilute standard 1X medium. It is useful for semisolid cultures, colony-formation assays, 3D cell culture, tissue engineering, metabolic research, and specialized cell-based assays.[4,5]
Automated Bioreactors & Robotics
For automated bioreactors, liquid-handling robots and closed perfusion loops with fine valves and in-line sensors, an optional 10 nm (0.01 µm) ultra-filtered grade of this medium is available.
- Total Particulate Exclusion: 0.01 µm filtration removes virtually all particulates down to the nanometer scale.
- Valve & Sensor Protection: keeps micro-valves, pumps and optical or electrochemical sensors free of deposits.
- Extended Perfusion Stability: supports long, uninterrupted perfusion runs with fewer line changes.
Inquiry Required: the 0.01 µm grade is made on request — email support@diagnocine.com with your catalog number and volume.
Colony-Formation Assays
Mix 1:1 with molten agar, agarose or methylcellulose for colony-formation and anchorage-independent growth assays at 1X medium strength.[4]
Collagen-Gel & Hydrogel Cultures
Fold in collagen, methylcellulose or hydrogels for gel-contraction studies and 3D constructs.[5]
Metabolic Research
1.0 g/L glucose at 1X (about 5.5 mM) sits close to physiological blood glucose, a common baseline for metabolic, glycolysis and insulin-signaling studies.
MSCs, Fibroblasts & Primary Cells
Low-glucose DMEM is a standard base for mesenchymal stem cell expansion, fibroblast culture and other primary cells after dilution to 1X.[3]
Organ-on-a-Chip & MPS
Microchannel-safe medium for perfused organ-, tissue- and body-on-a-chip platforms.[8,9,10]
Microscopy & Optical Sensing
Fewer particles means cleaner fields for colony counting, confocal imaging and on-chip biosensors.
