FluxMPS™ MCDB 201 Medium: 1X Liquid
FluxMPS™ DCP-M201H1X is a Microfluidics Suitable, quadruple-stage ultra-filtered MCDB 201 + HEPES formulation engineered for serum-free or low-protein culture of chick embryo fibroblasts and related primary cell models on organ-on-a-chip (OoC) and microphysiological system (MPS) platforms. 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. Formulation: [+] 1.441 g/L Glucose, [+] L-Glutamine, [+] Sodium Pyruvate, [+] Sodium Bicarbonate, [+] 30 mM HEPES, [+] Trace Elements.

Engineered where standard media fails
MCDB media formulated with trace element salts can form subvisible particulate aggregates when filtered at 0.22 µm under typical manufacturing conditions. These aggregates clog microfluidic channels, disrupt trace metal bioavailability, and confound primary cell phenotype. FluxMPS™ is built with four-stage sub-0.04 µm filtration and a < 0.05 EU/mL endotoxin release specification.
Particle-free trace element delivery
0.04 µm filtration ensures trace metal salts are fully dissolved — minimizing aggregate deposition in chip channels or culture vessels where trace metal precipitation could alter bioavailability.
Serum-free primary cell support
Trace element composition supports metalloenzyme activity (SOD, GPx, carbonic anhydrase) relevant to primary cell survival and function without serum supplementation.
Ultrapure-grade water
Ultrapure Type 1 water (18.2 MΩ·cm) limits ionic and trace-metal background that could compete with zinc, copper, and selenium uptake in low-serum primary cell culture.
Below TLR4 endotoxin threshold
< 0.05 EU/mL endotoxin release specification — below the reported TLR4 activation threshold — reduces the risk of LPS-driven inflammatory signaling that can confound primary cell phenotype in serum-free conditions.
HEPES-stabilized pH
HEPES (30 mM, pKa 7.3 at 37°C) supports stable pH for sensitive primary cell culture alongside bicarbonate buffering.
Customization on demand
pH, glucose, trace element concentrations, HEPES, and growth factor co-formulations available. Contact support@diagnocine.com.
Quadruple-stage filtration system
Four serial filtration stages reaching a final 0.04 µm polish — two dedicated prefilter-plus-final-filter pairs run in series, delivering sub-mycoplasma-scale particulate control and particle-free trace element delivery beyond what conventional 0.22 µm filtered MCDB media can offer.
-
1
0.1 µm Prefiltration I
Removes large aggregates including trace metal salt precipitates. 0.1 µm pore size is mycoplasma-retentive and protects the downstream 0.04 µm cartridge and chip geometries from fouling.
-
2
0.04 µm Final filtration I
First 0.04 µm pass; retains sub-micron particulates and trace-metal microaggregates that pass a standard 0.22 µm filter.
-
3
0.1 µm Prefiltration II
Second dedicated 0.1 µm prefilter, protecting the second 0.04 µm cartridge and providing redundant mycoplasma-retentive filtration.
-
4
0.04 µm Final filtration II — Polish
Ultimate polishing filter delivering the final 0.04 µm cut-off; aseptic fill & finish.
