FluxMPS™ MCDB 131 Medium w/o Sodium Bicarbonate: 1X Liquid

FluxMPS™ MCDB 131 Medium w/o Sodium Bicarbonate: 1X Liquid

FluxMPS™ DCP-M131-B1X is an MPS-grade, ultra-filtered MCDB 131 −Bicarbonate formulation engineered for serum-free or low-protein culture of Human Microvascular Endothelial Cells (HMVEC) 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: [+] Low Glucose (1000 mg/L), [+] L-Glutamine, [+] Sodium Pyruvate, [+] Trace Elements | [-] Sodium Bicarbonate.

• Trace element formulation — zinc, copper, selenium, manganese for metalloenzyme support and antioxidant activity in serum-free culture
• Optimized for: Human Microvascular Endothelial Cells (HMVEC), HUVEC, HAEC — CO₂-independent systems
• 0.04 µm final nano-filtration — trace elements delivered as dissolved ions, not particulate aggregates
• Quadruple-stage filtration: 0.1 µm pre-I → 0.04 µm pre-II → 0.1 µm sterile-I → 0.04 µm final polish
• Endotoxin < 0.05 EU/mL — below TLR4 activation threshold for sensitive primary cell models
• Ultrapure Type 1 water (18.2 MΩ·cm), ISO 13485:2016 QMS, ISO Class 5 fill

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.

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. 1

   0.1 µm Pre-filtration I — Large Particulate & Aggregate Removal

   Removes large aggregates including trace metal salt precipitates; protects downstream 0.04 µm membranes and chip geometries from fouling.

2. 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. 3

   0.1 µm Sterile-filtration I — Second-pass Redundancy

   Second-pass sterility redundancy; no breakthrough from Stage 1.

4. 4

   0.04 µm Sterile-filtration II — Final Polish

   Ultimate sub-mycoplasma polish; ISO Class 5 aseptic fill & finish.

Specialized cell models & OoC applications

FluxMPS™ DCP-M131-B1X was formulated specifically for Human Microvascular Endothelial Cells (HMVEC), HUVEC, HAEC — CO₂-independent systems in low-protein or serum-free conditions. The 0.04 µm filtered trace element matrix enables safe use in microfluidic chip architectures where conventional MCDB media would cause trace metal particulate fouling.

Automated Bioreactors & Robotics

Optional 0.01 µm (10 nm) ultra-filtered variant available for automated bioreactor perfusion where trace metal salt nanoparticulates in standard MCDB media cause valve fouling.

• Trace Metal Nanoparticulate Removal: 10 nm filtration removes sub-0.04 µm metal salt colloids invisible to standard QC
• Valve & Sensor Protection: Eliminates micro-fouling from trace element aggregates in automated systems
• Extended Perfusion Stability: Consistent trace element delivery over weeks-long primary cell culture
