FluxMPS™ Minimum Essential Medium (MEM), Low Glucose, NEAA & 25mM HEPES w/o L-Glutamine, Sodium Pyruvate: 1X Liquid

FluxMPS™ DCP-MEMH-QP1X 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), [+] Sodium Bicarbonate, [+] 25mM HEPES | [-] L-Glutamine, [-] Sodium Pyruvate.

  • 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

Why FluxMPS™

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.

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.

FAQ

Frequently asked questions

Common questions about FluxMPS™ DCP-MEMH-QP1X.

DCP-MEMH-QP1X is processed through a Quadruple-stage filtration system reaching 0.04 µm, delivering ultra-low particulate levels for MPS, OoC, and LoC platforms. MEM + Earle's Salts + NEAA with sub-mycoplasma filtration purity is particularly suited to primary neuronal, epithelial, and fibroblast OoC platforms.
FluxMPS™ uses four sequential filters ? 0.1 µm pre-filtration I, 0.04 µm pre-filtration II (mycoplasma barrier), 0.1 µm sterile-filtration I, and 0.04 µm final polish ? resulting in approximately 5× fewer particles and confirmed mycoplasma retention at every production stage.
Both omitted for independent fresh supplementation at user-defined concentrations. HEPES + bicarbonate provides dual-buffer pH stability throughout. Enables precise nitrogen (glutamine) and secondary carbon (pyruvate) control for primary cell metabolic flux studies with stable pH during sampling events outside the incubator.
5% CO₂ recommended (dual HEPES + bicarbonate buffering; HEPES alone maintains pH without CO₂).
NEAA are pre-loaded, providing non-essential nitrogen and carbon skeleton support. This reduces the metabolic burden on primary cells that must synthesize these amino acids de novo from glutamine and glucose improving viability in low-serum conditions and reducing ammonia accumulation.
FluxMPS™ DCP-MEMH-QP1X is produced to meet < 0.05 EU/mL by LAL assay (USP <85>). For primary cells, endotoxin activates TLR4, altering fibroblast activation state, neuronal inflammatory gene expression, and epithelial barrier function.
Yes. Full CoA per lot covers: appearance, pH (USP <791>), osmolality (USP <785>), sterility (USP <71>), endotoxin (USP <85>), mycoplasma, particulate count (USP <788> Method 2), and raw-material traceability. Request at support@diagnocine.com.
