FluxMPS™ Minimum Essential Medium (MEM), Low Glucose, NEAA & 25mM HEPES w/o Sodium Pyruvate, Phenol Red: 1X Liquid
FluxMPS™ DCP-MEMH-PR1X is an MPS-grade, ultra-filtered MEM Low Glucose + NEAA + 25mM HEPES formulation engineered for Primary fibroblasts and related cell models on organ-on-a-chip (OoC) and microphysiological system (MPS) platforms. Processed through a Quadruple-stage filtration system (0.1 µm ×2 + 0.04 µm ×2), it delivers approximately 5× lower particulate counts than conventional 0.22 µm–filtered media. NEAA pre-loaded — reduces metabolic burden on primary cells. HEPES (25 mM, pKa 7.3 at 37°C) provides robust CO₂-independent pH buffering. Formulation: [+] Earle's Salts, [+] NEAA, [+] Low Glucose (1000 mg/L), [+] L-Glutamine, [+] Sodium Bicarbonate, [+] 25mM HEPES | [-] Sodium Pyruvate, [-] Phenol Red.
- Low Glucose (1.0 g/L) — physiological carbon source for primary cells sensitive to high glucose.
- NEAA included reduces metabolic burden and ammonia from de novo synthesis
- 25 mM HEPES (pKa 7.3 at 37°C) — pH-stable without CO₂; ideal for open-air handling, flow cytometry prep, and atmospheric incubation
- 0.04 µm final nano-filtration — sub-mycoplasma purity; < 0.05 EU/mL endotoxin for sensitive primary and hematopoietic cell cultures
- Quadruple-stage filtration: 0.1 µm pre-I → 0.04 µm pre-II → 0.1 µm sterile-I → 0.04 µm final polish

Engineered for primary cell culture where standard media fails
MEM with Earle's Salts is the primary cell biologist's medium but conventional 0.22 μm filtered MEM passes mycoplasma, particulates, and endotoxin that alter primary cell phenotype. FluxMPS™ eliminates these failure modes while preserving the full nutritional profile primary cells depend on.
Microchannel-safe purity
0.04 µm final filtration; USP <788> particulate compliance. Particle-free primary cell media prevents chip channel clogging and mycoplasma-driven phenotypic drift.
Primary cell?optimized formulation
MEM + Earle's Salts + NEAA: the established standard for primary fibroblasts, neurons, epithelial, and vascular cells.
HEPES: CO₂-stable pH
25 mM HEPES prevents pH rise during open-air suspension culture handling, flow cytometry prep, and multi-well assay setup outside CO₂ incubators.
Below TLR4 endotoxin threshold
< 0.05 EU/mL endotoxin below the TLR4 activation threshold. For primary cells, prevents LPS-driven fibroblast activation, neuroinflammation, and epithelial barrier disruption.
NEAA reduces metabolic burden
Pre-loaded NEAA reduces de novo synthesis burden on primary cells, improving viability in low-serum conditions and reducing ammonia accumulation.
