FluxMPS™ RPMI 1640 Medium w/o Sodium Pyruvate: 1X Liquid
FluxMPS™ DCP-RPMI-P1X is a Microfluidics Suitable, ultra-filtered RPMI 1640 formulation engineered for T cells, B cells, NK cells, PBMCs, and hematopoietic cancer lines 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 reaches a 0.04 µm final cut-off — five times finer than the 0.22 µm membranes used for conventional sterile filtration. Formulation: [+] 2 g/L Glucose, [+] L-Glutamine, [+] Sodium Bicarbonate, [+] Phenol Red | [-] Sodium Pyruvate.
- High-glucose RPMI 1640 base (2000 mg/L / 2.0 g/L D-Glucose) with L-Glutamine (300 mg/L) and sodium bicarbonate buffering (2000 mg/L) for standard 5% CO₂ incubation
- Sodium pyruvate omitted by design, allowing researchers to add a defined pyruvate concentration for OXPHOS/glycolytic-flux studies in lymphocytes and hematopoietic cell lines
- Reduced glutathione (1.000 mg/L) included for redox and antioxidant support in redox-sensitive immune cell types
- Processed through a Quadruple-stage filtration system (0.1 µm ×2 + 0.04 µm ×2) reaching a 0.04 µm final cut-off
- Endotoxin release specification < 0.05 EU/mL (LAL, USP <85>), controlled per manufacturing batch

Engineered where standard media fails
Conventional 0.22 µm–filtered RPMI passes mycoplasma-sized particles, subvisible particulates, and microaggregates that can accumulate in microfluidic channels and confound immune cell assays. FluxMPS™ is built to address these failure modes.
Microchannel-safe purity
0.04 µm final filtration; USP <788> particulate testing. Formulated for suspension immune cell OoC and flow cytometry workflows where particulate load matters.
Total metabolic control
Sodium pyruvate is omitted by design, letting you define the exact secondary carbon source and concentration for OXPHOS and glycolytic-flux studies, alongside 2.0 g/L D-glucose and 300 mg/L L-glutamine already in the base formulation.
Ultrapure-grade water
Type 1 water (18.2 MΩ·cm) is used in formulation, controlling trace-metal and organic-carbon (TOC) contamination during manufacture.
Low background for imaging
Sub-micron filtration reduces particulate background for flow cytometry, ELISA, and confocal imaging workflows. Note: this formulation contains phenol red and riboflavin; a phenol-red-free FluxMPS™ variant is available where optical/fluorescence background must be minimized.
Rich, stable nutrient profile
RPMI 1640 contains reduced glutathione and a balanced profile of vitamins and amino acids optimized for lymphocyte and hematopoietic cell culture, released per lot.
Customization on demand

Performance vs. conventional media
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, with mycoplasma-retentive prefiltration applied at every production stage.

Leukemia & Lymphoma Lines
RPMI supports Jurkat, Raji, K562, HL-60, and other hematopoietic cancer lines where DMEM-based media would alter proliferation and signaling.
Immune Cell OoC
0.04 µm filtered RPMI for tumor-immune interaction chips, vascular-immune OoC, and lymph node-on-chip models where particulate-reduced media is preferred.
CAR-T & TIL Expansion
Low endotoxin (<0.05 EU/mL release specification) supports CAR-T manufacturing and TIL expansion protocols sensitive to LPS-driven activation artefacts.
Immune Cell Metabolic Flux
Defined RPMI base for ¹³C isotope tracing and LC-MS/NMR metabolomics of lymphocyte activation states. Not compatible with Agilent Seahorse XF assays, which require bicarbonate-free, phenol red-free medium.
