FluxMPS™ MCDB 302 Medium
MCDB 302 is a chemically defined, F-12-derived medium originally developed by Hamilton and Ham in 1977 to support protein-free clonal growth of Chinese Hamster Ovary (CHO) cells — the first protein-free medium demonstrated for CHO clonal growth. FluxMPS™ delivers this formulation through a 0.04 micron quadruple-stage filtration process engineered for microfluidic, Organ-on-Chip (OoC), and Lab-on-Chip (LoC) platforms.
- Two ready-to-use FluxMPS™ configurations: MCDB 302 (with sodium bicarbonate) and MCDB 302 w/o Bicarbonate
- Originally formulated for the cultivation of Chinese Hamster Ovary (CHO) cells; valued in biopharmaceutical research for high-density cell growth and protein production
- Standard glucose concentration of 1.801 g/L at 1X
- Both configurations include L-Glutamine, Sodium Pyruvate, HEPES, and Phenol Red as standard, plus a trace-element supplement; Sodium Bicarbonate is included in the standard configuration and omitted in the w/o Bicarbonate configuration
- Purified through FluxMPS™ quadruple-stage 0.04 micron filtration for microfluidic and Organ-on-Chip / Tissue-on-Chip / Lab-on-Chip compatibility
- Supports high-density cell growth and recombinant protein / monoclonal antibody production workflows as a base medium, supplementable with growth factors, hormones, or low levels of serum

About MCDB 302 Medium
MCDB media were developed for the culture of specific cell types without a serum supplement. The media were supplemented with growth factors, hormones, trace elements, or low levels of dialyzed fetal bovine serum protein (FBSP), and each MCDB medium was formulated for a specific cell type: MCDB 105 and 110 for rapid clonal growth of normal human diploid cells, MCDB 131 originally for human micro-vascular endothelial cells (HMVEC), and MCDB 151, 201, and 302 originally for human keratinocytes, clonal growth of chick embryo fibroblasts, and CHO cells respectively.
MCDB 302 Medium is a specialized cell culture medium in the MCDB series, developed to support the growth of specific cell types in low-protein or serum-free conditions. Originally formulated for the cultivation of Chinese Hamster Ovary (CHO) cells, MCDB 302 has become an essential tool in biotechnology and pharmaceutical research. It is characterized by a carefully balanced composition of inorganic salts, amino acids, vitamins, and other nutrients tailored to promote optimal growth and productivity of CHO cells.
MCDB 302 is particularly valued in the biopharmaceutical industry for its ability to support high-density cell growth and protein production, making it well suited to the manufacture of recombinant proteins and monoclonal antibodies. Researchers often use MCDB 302 as a base medium, which can be further supplemented with growth factors, hormones, or low levels of serum to meet specific experimental or production requirements. Its defined formulation allows for greater control over culture conditions, facilitating the development of serum-free and chemically defined media for large-scale bioprocessing applications.
Origins & Development
MCDB media are a family of chemically defined, cell-type-specific basal formulations developed at the Department of Molecular, Cellular and Developmental Biology (MCDB) at the University of Colorado, Boulder, primarily by Richard G. Ham and Wallace L. McKeehan during the 1970s and 1980s. The department acronym gives the series its name; the department itself was founded in 1968 by pioneering cell biologist Keith Porter, its first chair. Unlike the classical Eagle-lineage media (BME, MEM, DMEM), which were designed as general-purpose basal formulations to be supplemented with serum, each MCDB medium was engineered from the ground up, qualitatively and quantitatively, to support the clonal growth and long-term maintenance of one specific, defined cell type.
The MCDB program was catalyzed by a 1976 discovery: McKeehan, Hamilton, and Ham reported in PNAS that selenium is an essential trace nutrient for clonal growth of WI-38 diploid human fibroblasts at minimal serum-protein concentrations, and that higher serum levels had simply been masking the requirement by supplying selenium as a contaminant. This finding showed that systematic trace-element supplementation could substantially reduce serum dependence and directly stimulated the formal MCDB series, beginning with MCDB 104 in 1977.
In parallel in 1977, Hamilton and Ham published MCDB 301 and 302 in In Vitro (13(9): 537-547) as protein-free media for the clonal growth of Chinese Hamster Ovary (CHO) cells. These F-12-derived modifications provided the first demonstration that CHO cells could proliferate clonally without serum or protein supplementation, laying the foundation for modern serum-free CHO bioproduction. In 1979, Ham and McKeehan codified the principles, nomenclature, and nutritional basis of the entire MCDB program in "Media and growth requirements," Chapter 5 of Methods in Enzymology (58: 44-93), which remains a key primary reference for the series.

Distinguishing Features Documented Across the MCDB Series
The following features are documented across the characterized MCDB-series media in Diagnocine's source materials (chiefly MCDB 104, 105, 110, 131, 151, 152, 153, 201); MCDB 301/302-specific per-component values were not published in these sources beyond the "with Trace Elements" designation shown in the configuration matrix above.
- Comprehensive trace-element panel covering selenium, zinc, copper, iron, manganese, molybdenum, vanadium, nickel, tin, and silicon — elements absent from DMEM, MEM, BME, and RPMI 1640
- Folinic acid (leucovorin) used in place of folic acid in MCDB 105 and MCDB 131, bypassing the dihydrofolate reductase activation step
- Adenine supplementation as a free purine source (1.7 mg/L in MCDB 105 to 30.9 mg/L in MCDB 153), absent from classical Eagle media (DMEM, MEM)
- Thymidine inclusion as a preformed pyrimidine nucleoside, allowing cells to bypass de novo synthesis
- Putrescine dihydrochloride, a polyamine growth factor and precursor to spermidine and spermine, absent from DMEM, MEM, BME, RPMI 1640, and IMDM
- Low or ultra-low calcium in keratinocyte formulations (MCDB 153: 4.411 mg/L CaCl2.2H2O, ~0.03 mM), a key regulatory lever for stratification and differentiation
- High Mg2+ in MCDB 131 (1204 mg/L, ~10 mM vs 0.8 mM in its parent MCDB 402), the single most influential adjustment reported by Knedler and Ham
- HEPES as a flexible buffering strategy in MCDB 105 and 153 (supplied without sodium bicarbonate; bicarbonate/CO2 added by the user when desired), versus bicarbonate buffering in MCDB 131

FluxMPS™ — Precision Cell Culture Media for Microphysiological Systems
Built for the architecture of the future. Not the flask of the past.
Traditional cell culture media were formulated for static well plates and flasks — environments that tolerate impurities, precipitates, and particle loads that would immediately compromise a microfluidic system. FluxMPS™ was designed from the ground up for Organ-on-Chip (OoC), Tissue-on-Chip (ToC), and Lab-on-Chip (LoC) platforms, where the medium itself is part of the instrument.
Purity That Protects Your Platform
FluxMPS™ is purified to 0.04 microns — finer than any ready-to-use cell culture media currently available. At this level, the microscopic particulates and protein aggregates that silently block micro-channels, disrupt laminar flow, and generate false biological signals are eliminated before the media ever reaches your chip.
The result: your platform stays operational, your data stays clean, and your biology drives the result — not your media.
Engineered for Flow, Not Just Growth
The name FluxMPS™ reflects its core design principle. Every component is optimized for consistent, laminar flow performance across:
- Complex micro-channel geometries
- Capillary-bed and vascular simulations
- Long-term automated perfusion studies running continuously for weeks
Zero-clogging performance is not a feature — it is the baseline specification.
Applications & Performance
| Application | What FluxMPS™ Delivers |
|---|---|
| Microfluidics | Stable shear stress; no channel blockage |
| Metabolic Tracing | Ultra-pure matrix with no contaminant interference |
| Long-term Perfusion | Consistent formulation stability over weeks of continuous flow |
| Organ-on-Chip | Optical clarity for real-time imaging and integrated biosensing |
Regulatory Foundation
FluxMPS™ is formulated to support FDA-recognized physiological modeling standards, providing a validated, reproducible media foundation for drug discovery, toxicology screening, and translational research. When your downstream data needs to stand up to regulatory scrutiny, your upstream media cannot be an afterthought.
The Bottom Line
Microfluidic platforms are precision instruments. They require precision inputs.
