FluxMPS™ Leibovitz's L-15 Medium w/o L-Glutamine, Phenol Red: 1X Liquid

Contains Calcium Contains Magnesium Contains Sodium Pyruvate Without L-Glutamine Without Phenol Red

Microfluidics Suitable, quadruple-stage ultra-filtered (0.1 µm ×2 + 0.04 µm ×2) 1X liquid Leibovitz's L-15 medium engineered for microfluidic channels, organ-on-a-chip (OoC), and microphysiological systems (MPS). This CO₂-independent, galactose-based formulation omits L-glutamine and phenol red for applications requiring reduced background or user-controlled glutamine supplementation. Manufactured under ISO 13485:2016 in an ISO Class 5 fill environment using Ultrapure Type 1 water (18.2 MΩ·cm). 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.

  • Quadruple-stage filtration to a 0.04 µm final cut-off — mycoplasma-retentive prefiltration and sub-micron particulate reduction
  • Endotoxin release specification: < 0.05 EU/mL (USP <85> BET, per-batch release)
  • Galactose-based (0.9 g/L), glucose-free carbon source with 550 mg/L sodium pyruvate — CO₂-independent, phosphate-buffered, bicarbonate-free
  • L-Glutamine and Phenol Red omitted for user-controlled supplementation and reduced optical background applications
  • Ultrapure Type 1 water (18.2 MΩ·cm) — low trace-metal and organic-carbon background
  • USP <788> Method 1 (light obscuration) particulate compliance — supports narrow microfluidic channel geometries

Why FluxMPS™

Engineered where standard media fails

Conventional 0.22 µm filtered media allows mycoplasma (0.2–0.3 µm), sub-visible particulates, and microaggregates to pass freely — clogging microchannels, corrupting biosensors, and invalidating metabolic assays. FluxMPS™ closes that gap.

filter_alt

Microchannel-safe purity

0.04 µm final filter and USP <788> Method 1 particulate compliance support unobstructed flow in narrow microfluidic channels.

Total metabolic control

A defined galactose-based carbon source and sodium pyruvate level support Warburg-effect studies, glycolysis inhibition, and ¹³C metabolic tracing.

Purity Architecture

Quadruple-stage filtration system

FluxMPS™ Leibovitz's L-15 Medium undergoes a validated four-stage sequential filtration process reaching a final pore size of 0.04 µm — two dedicated prefilter-plus-final-filter pairs run in series, engineered to reduce particulate and bioburden levels beyond conventional 0.22 µm-filtered media.

  1. 1

    0.1 µm Prefiltration I

    Removes large particulates, cell debris, and protein aggregates; protects the first 0.04 µm cartridge.

  2. 2

    0.04 µm Final filtration I

    First 0.04 µm pass; retains sub-micron particulates and microaggregates that pass a 0.22 µm filter.

    Ultimate polishing filter; aseptic fill in a validated ISO Class 5 (Class 100) laminar-flow workstation.

Performance vs. conventional media

By USP <788> Method 1 (light obscuration), FluxMPS™ delivers approximately 5× fewer particles ≥10 µm vs. standard 0.22 µm filtered media — a meaningful difference for long-duration perfusion in narrow microfluidic channels.

µm Final filter — sub-mycoplasma polishing
Sterility & Mycoplasma: 14-day USP <71> sterility tested per lot. The 0.1 µm prefiltration stages provide mycoplasma-retentive filtration (not tested per lot). Mycoplasma range 0.2–0.3 µm, well above the 0.04 µm final cut-off.
Grade: This product is Microfluidics Suitable, filtered to a 0.04 µm final cut-off. It is not an MPS Grade product — that designation is reserved for the 0.01 µm ultra nano-filtered line, which adds 0.02 µm and 0.01 µm stages after the 0.04 µm polish.

FAQ

Frequently asked questions

Common questions about FluxMPS™ Leibovitz's L-15 Medium w/o L-Glutamine, Phenol Red: 1X Liquid (DCP-LL15-QR1X).

Yes. DCP-LL15-QR1X is engineered for organ-on-a-chip, microfluidic, and MPS applications. The 0.04 µm final filtration stage is designed to reduce mycoplasma-scale particulates and sub-micron contaminants that can cause microchannel clogging in standard 0.22 µm media.
Four sequential stages (0.1 µm ×2 + 0.04 µm ×2) provide additional retention of mycoplasma-scale particulates and sub-visible particulate matter beyond conventional 0.22 µm filtration, consistent with USP <788> Method 1 (light obscuration) particulate limits — approximately 5× fewer particles ≥10 µm by count.
DCP-LL15-QR1X combines a defined galactose-based carbon source (0.9 g/L D-galactose) and sodium pyruvate (550 mg/L) in an ultra-pure, quadruple-filtered base, with L-glutamine and phenol red omitted for applications requiring user-controlled glutamine supplementation or reduced optical background. Add L-glutamine or a stabilized glutamine substitute directly, or request a custom pre-supplemented formulation at support@diagnocine.com.
No. DCP-LL15-QR1X contains no sodium bicarbonate and is phosphate-buffered, making it suitable for CO₂-independent incubation. HEPES can be added on request for applications requiring additional pH buffering outside a controlled atmosphere.
Yes. DCP-LL15-QR1X is a basal medium compatible with FBS (2–10%), human serum, GlutaMAX, EGF, FGF, VEGF, and antibiotics. Pre-filter serum or protein-containing additions through a 0.2 µm low-protein-binding PES or PVDF filter before combining; defined, protein-free additions may be filtered at 0.1 µm. Do not use a 0.04 µm filter on supplements — it will strip serum proteins and clog.
Endotoxin is controlled per manufacturing batch. Every batch is tested by LAL assay (USP <85> Bacterial Endotoxins Test; assay sensitivity 0.005 EU/mL) and must meet the release specification of < 0.05 EU/mL before release. Lot-specific results are reported on the CoA — request at support@diagnocine.com.
Yes — a full CoA per lot includes: lot number, expiry, appearance, pH (USP <791>), osmolality (USP <785>), endotoxin (USP <85>), sterility (USP <71>), mycoplasma control by filtration, particulate count (USP <788> Method 1), and cultural response. Email support@diagnocine.com.
