FluxMPS™ MCDB 153 Medium without Sodium Bicarbonate: 1X Liquid
FluxMPS™ DCP-M153H-B1X is an MPS-grade, ultra-filtered MCDB 153 −Bicarbonate +HEPES formulation engineered for serum-free or low-protein culture of Human Epidermal Keratinocytes 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 — ensuring trace elements are delivered particle-free and endotoxin is below TLR4 activation threshold. Formulation: [+] 1.081 g/L Glucose, [+] L-Glutamine, [+] Sodium Pyruvate, [+] 28mM HEPES, [+] Trace Elements | [-] Sodium Bicarbonate.
- Trace element formulation — zinc, copper, selenium, manganese for metalloenzyme support and antioxidant activity in serum-free culture
- Optimized for: Human Epidermal Keratinocytes, CHO cells, Chicken Embryo Fibroblasts — CO₂-independent
- 28 mM HEPES (pKa 7.3 at 37°C) — pH-stable without CO₂ for open-top chips and atmospheric platforms
- 0.04 µm final nano-filtration — trace elements delivered as dissolved ions, not particulate aggregates

Engineered where standard media fails
MCDB media formulated for primary cells contain trace element salts that 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 activate innate immune signaling in sensitive primary cell models. FluxMPS™ eliminates these failure modes with four-stage sub-0.04 µm filtration and < 0.05 EU/mL endotoxin.
Particle-free trace element delivery
0.04 µm filtration ensures trace metal salts are fully dissolved — no aggregate deposition in chip channels or culture vessels where trace metal precipitation would alter bioavailability.
Serum-free primary cell support
Trace element composition supports metalloenzyme activity (SOD, GPx, carbonic anhydrase) critical for primary cell survival and function without serum supplementation.
Ultrapure-grade water
Ultrapure Type 1 water (18.2 MΩ·cm) eliminates ionic contaminants that would compete with trace element uptake by low-serum primary cells.
Below TLR4 endotoxin threshold
< 0.05 EU/mL endotoxin — below the TLR4 activation threshold — prevents LPS-driven inflammatory signaling that confounds primary cell phenotype in serum-free conditions.
HEPES CO₂-stable pH
HEPES (28 mM, pKa 7.3 at 37°C) maintains stable pH for sensitive primary cell differentiation without CO₂ dependency.

Quadruple-stage filtration system
Four serial filtration stages reaching a final 0.04 µm polish under ISO Class 5 aseptic conditions — delivering sub-mycoplasma purity and particle-free trace element delivery unavailable from conventional 0.22 µm filtered MCDB media.
-
1
0.1 µm Pre-filtration I — Large Particulate & Aggregate Removal

-
2
0.04 µm Pre-filtration II — Mycoplasma Barrier
Retains mycoplasma (0.1–0.3 µm) and residual fine particulates — absent from standard 0.22 µm filtration.
-
3
0.1 µm Sterile-filtration I — Second-pass Redundancy
Second-pass sterility redundancy; no breakthrough from Stage 1.
-
4
0.04 µm Sterile-filtration II — Final Polish
Ultimate sub-mycoplasma polish; ISO Class 5 aseptic fill & finish.
Performance vs. conventional MCDB media
FluxMPS™ DCP-M153H-B1X delivers approximately 5× lower particulate counts than standard 0.22 µm filtered MCDB 153 −Bicarbonate +HEPES, with confirmed mycoplasma barrier and particle-free trace element delivery at every production stage.
