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

Contains Sodium Bicarbonate Contains Phenol Red Contains HEPES Contains Calcium Contains Magnesium Contains Glucose Without L-Glutamine Without Sodium Pyruvate

FluxMPS™ DCP-MEMH-QP1X is a Microfluidics Suitable, quadruple-stage ultra-filtered (0.1 µm ×2 + 0.04 µm ×2) MEM Low Glucose + NEAA + 25mM HEPES formulation engineered for primary fibroblasts, neurons, epithelial and vascular 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. NEAA is pre-loaded to reduce metabolic burden on primary cells, while 25 mM HEPES (pKa 7.3 at 37°C) provides robust pH buffering independent of CO2. Formulation: [+] Earle's Salts, [+] NEAA, [+] Low Glucose (1000 mg/L), [+] Sodium Bicarbonate, [+] 25mM HEPES, [+] Phenol Red | [-] L-Glutamine, [-] Sodium Pyruvate.

  • Low Glucose (1.0 g/L) — physiological carbon source for primary cells sensitive to high-glucose media stress
  • NEAA pre-loaded — reduces de novo amino acid synthesis burden and ammonia accumulation in primary fibroblasts, neurons and epithelial cells
  • 25 mM HEPES (pKa 7.3 at 37°C) — CO2-independent pH stability for open-bench handling, flow cytometry prep and atmospheric incubation
  • Quadruple-stage filtration (0.1 µm ×2 + 0.04 µm ×2) reaching a 0.04 µm final polish — mycoplasma-retentive purity for microfluidic and OoC platforms
  • Endotoxin release specification < 0.05 EU/mL (LAL, USP <85>) — below the TLR4 activation threshold for sensitive primary and hematopoietic cultures
  • L-Glutamine and sodium pyruvate withheld for independent, user-defined supplementation and precise metabolic flux control
  • Manufactured under an ISO 13485:2016 quality management system with a per-lot Certificate of Analysis
  • Custom pH, glucose and HEPES concentration formulations available on request

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™ is Microfluidics Suitable, addressing these failure modes while preserving the full nutritional profile primary cells depend on.

Microchannel-safe purity

0.04 µm final filtration; USP <788> Method 1 particulate compliance. Low-particulate primary cell media prevents chip channel clogging.

HEPES: CO2-stable pH

25 mM HEPES helps stabilize pH 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 release specification — below the TLR4 activation threshold. For primary cells, this specification is relevant to avoiding LPS-driven fibroblast activation, neuroinflammatory signaling, and epithelial barrier disruption.

NEAA reduces metabolic burden

Pre-loaded NEAA reduces de novo synthesis burden on primary cells, supporting viability in low-serum conditions and reducing ammonia accumulation.

FAQ

Frequently asked questions

Common questions about FluxMPS™ DCP-MEMH-QP1X.

DCP-MEMH-QP1X is Microfluidics Suitable, 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 mycoplasma-retentive filtration purity is particularly suited to primary neuronal, epithelial, and fibroblast OoC platforms.
 
Both are omitted for independent fresh supplementation at user-defined concentrations. HEPES + sodium bicarbonate together provide dual-buffer pH stability throughout. This enables precise nitrogen (glutamine) and secondary carbon source (pyruvate) control for primary cell metabolic flux studies, with stable pH during sampling events outside the incubator.
5% CO2 is recommended for optimal bicarbonate-mediated pH control. The 25 mM HEPES component provides supplemental, CO2-independent buffering for extended bench-top handling outside the incubator.
Yes. Serum and other protein-containing supplements should be pre-filtered through a 0.2 µm low-protein-binding PES or PVDF membrane prior to addition — a 0.04 µm membrane will strip serum of the very lipoproteins and growth factors that make it functional and is not recommended for this purpose. Defined, protein-free additions may use a 0.1 µm membrane.
Every DCP-MEMH-QP1X batch is released against a specification of < 0.05 EU/mL, tested by LAL assay per USP <85> (assay sensitivity 0.005 EU/mL). Endotoxin is controlled per manufacturing batch, not per unit. For primary cells, endotoxin can activate 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-retentive filtration status, particulate count (USP <788> Method 1), and raw-material traceability. Request at support@diagnocine.com.
