FluxMPS™ Click’s Medium (EHAA) Eagle Hanks’ Amino Acids w/o L-Glutamine, Sodium Bicarbonate, Mercaptoethanol: 2X Liquid
FluxMPS™ Click's Medium (EHAA) Eagle Hanks' Amino Acids w/o L-Glutamine, Sodium Bicarbonate, Mercaptoethanol: 2X Liquid
Double-strength (2X) Click's Medium (EHAA) for murine T cells, lymphocytes, hybridomas and other immune-cell models, ultra-filtered through a quadruple-stage 0.1 µm / 0.04 µm filtration system. With a bicarbonate-free base for user-defined buffering and no 2-mercaptoethanol, it is approximately 5× cleaner than conventional 0.22 µm-filtered media by particulate count.
- 2X concentrate: mix with an equal volume of another solution for a final 1X nutrient concentration
- Quadruple-stage filtration: 0.1 µm membrane filtered twice, 0.04 µm membrane filtered twice
- 0.04 µm nano-filtration final polish acts as a mycoplasma barrier

Engineered where standard media fails
Conventional Click's Medium is sterile-filtered once at 0.22 µm. That pore size can pass mycoplasma and leaves subvisible particulates that settle in microchannels and add noise to optical readouts — and mycoplasma is a known confounder of lymphocyte and hybridoma work.[10,11] FluxMPS™ Click's Medium keeps the EHAA formulation and removes that failure mode.
Microchannel-safe purity
A 0.04 µm final filter and USP <788> particulate control keep subvisible debris out of chips, tubing and porous membranes.
Total metabolic control
Defined 2,000 mg/L glucose, 550 mg/L sodium pyruvate and no L-glutamine in the 2X (half that at 1X).
Ultrapure-grade water
Made with Ultrapure Type 1 water (18.2 MΩ·cm) and released at < 0.05 EU/mL endotoxin by USP <85>.
Low background for imaging
Particle-depleted medium reduces scatter and debris artifacts in flow cytometry, confocal imaging and on-chip sensing.
Nucleoside-enriched EHAA base
41 components, including Eagle's amino acids with Hanks' salts plus adenosine, cytosine, guanosine and uridine.

Quadruple-stage filtration system
Every lot of DCP-CM-QB2X is membrane filtered at 0.1 µm twice and 0.04 µm twice — a ready-to-dilute 2X Click's Medium polished to a 0.04 µm final pore size, a purity level single-pass 0.22 µm media cannot reach.

Where FluxMPS™ Click's Medium fits
Click’s Medium (EHAA) is a specialized cell culture medium developed for studying immune responses in mouse spleen cells.[1,2] It is commonly used for the culture of murine T cells, lymphocytes, hybridomas, and other immune-cell models in immunology, antibody, and cell-based research.[3]
Click’s Medium (EHAA) 2X is a double-strength formulation designed for research workflows that require the medium to be mixed with an equal volume of another solution while maintaining a final 1X nutrient concentration. It is useful for preparing customized media, incorporating supplements or treatment solutions, and supporting specialized T-cell, lymphocyte, hybridoma, and other immune-cell culture applications.
Automated Bioreactors & Robotics
For automated bioreactors, liquid-handling robots and closed perfusion loops with fine valves and in-line sensors, an optional 10 nm (0.01 µm) ultra-filtered grade of this medium is available.
- Total Particulate Exclusion: 0.01 µm filtration removes virtually all particulates down to the nanometer scale.
- Valve & Sensor Protection: keeps micro-valves, pumps and optical or electrochemical sensors free of deposits.
- Extended Perfusion Stability: supports long, uninterrupted perfusion runs with fewer line changes.
Inquiry Required: the 0.01 µm grade is made on request — email support@diagnocine.com with your catalog number and volume.
Murine T Cells & Lymphocytes
Culture of mouse spleen cells, T cells and other lymphocytes for in vitro immune-response, activation and proliferation studies.[1,2]
Hybridoma Culture
Base medium for hybridoma growth and antibody production workflows, with serum or defined supplements.[3]
Immune-on-Chip & MPS
Microchannel-safe medium for perfused immune-cell, lymphoid-tissue and other organ-on-a-chip platforms.[6,7,8,9]
Co-culture & Functional Assays
The 2X format makes it simple to fold in treatment solutions, cytokines or test compounds at a final 1X medium.
Metabolic Flux Analysis
A defined glucose, pyruvate and amino-acid background for immunometabolism, isotope tracing and respirometry.
Microscopy & Flow Cytometry
Fewer particles means cleaner fields and fewer debris events in confocal imaging and flow analysis.
