FluxMPS™ RPMI 1640

FluxMPS™ DCP-RPMI-QR1X is an MPS-grade, ultra-filtered RPMI 1640 formulation engineered for Hematopoietic cells 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.

Why FluxMPS™

Engineered where standard media fails

Conventional 0.22 µm–filtered RPMI passes mycoplasma, subvisible particulates, and endotoxin fragments that activate TLR4 and confound immune cell assays. FluxMPS™ eliminates these failure modes.

FAQ

Frequently asked questions

Common questions about FluxMPS™ DCP-RPMI-QR1X — RPMI 1640.

DCP-RPMI-QR1X is processed through a Quadruple-stage filtration system reaching 0.04 µm final pore size. RPMI 1640 with sub-mycoplasma filtration purity is suited to immune cell OoC, tumor-immune interaction chips, and lymphocyte perfusion models where standard RPMI would cause particulate TLR4 activation.

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.

Phenol red removed for autofluorescence-free flow cytometry and imaging; L-glutamine removed for fresh supplementation. Preferred for fluorescence-monitored immune cell assays with precise nitrogen control.

5% CO₂ required (sodium bicarbonate buffering).

Yes. Add FBS (5–10%), serum-free supplements, growth factors, or antibiotics as required. Contact support@diagnocine.com for custom co-formulation.

FluxMPS™ DCP-RPMI-QR1X is produced to meet < 0.05 EU/mL by LAL assay (USP <85>). For immune cells, endotoxin above 0.1 EU/mL activates TLR4/NF-κB, inducing cytokines and altering lymphocyte activation state independently of experimental conditions.

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.
