Engineered where standard running buffers fall short
Conventional 0.22 µm-filtered running buffers can carry subvisible particulates and inconsistent DNase/RNase testing that put sensitive RNA samples at risk during electrophoresis and blotting. FluxMPS™ MOPS Running Buffer [10X] is built to remove those variables at the source.
Quadruple-stage purity
Sequential 0.1 µm (twice) and 0.04 µm (twice) filtration removes fine particulates that could interfere with RNA or protein migration and gel imaging.
Precise, stable pH
200 mM zwitterionic MOPS buffered to pH 7.0, paired with sodium acetate and EDTA, holds a consistent ionic environment across the run.
Ultrapure-grade water
Manufactured with Ultrapure Type 1 water (18.2 MΩ·cm) consistent with USP <85> laboratory water quality practice.
Low background for downstream assays
A clean, defined formulation supports UV/VIS spectrophotometric analysis and Northern blot hybridization without introducing background noise.
Defined, traceable composition
MOPS, sodium acetate, and EDTA are each held to a declared concentration and verified for DNase and RNase absence prior to release.
Customization on demand
Alternate concentrations, pH, and added chemicals, compounds, proteins, or supplements can be formulated on request.
Quadruple-stage filtration system
MOPS Running Buffer [10X] is sterile-filtered through a 0.1 µm membrane twice and a 0.04 µm membrane twice, giving RNA and protein electrophoresis workflows a buffer built to a materially cleaner standard than a single-pass 0.22 µm filtration.
-
1
0.1 µm Pre-filtration I
First-pass removal of large particulates and aggregates ahead of downstream polishing.
-
2
0.04 µm Pre-filtration II
Fine particulate and bioburden retention, reducing the load carried into sterile filtration.
-
3
0.1 µm Sterile-filtration I
Second-pass redundancy through a 0.1 µm membrane in a sterile filtration environment.
-
4
0.04 µm Sterile-filtration II — Final Polish
Final polish through a 0.04 µm membrane, completed in a sterile environment.
Performance vs. conventional buffer
Sequential 0.1 µm (applied twice) and 0.04 µm (applied twice) filtration removes finer particulates than a single 0.22 µm pass, supporting cleaner RNA and protein electrophoresis results with reduced background interference. This tiered approach also helps guard against mycoplasma contamination, since the smallest mycoplasma species measure approximately 0.2 microns.

Where MOPS Running Buffer [10X] is used
A concentrated, zwitterionic running buffer purpose-built for RNA and protein electrophoresis workflows, with a formulation clean enough for downstream imaging and detection.
Automated Bioreactors & Robotics
For laboratories running automated liquid handling or robotic gel-loading platforms, an optional 0.01 µm (10 nm) ultra-filtered variant of this buffer is available to further protect fine-bore tubing, valves, and sensors from particulate accumulation over extended runs.
- Total Particulate Exclusion: The 10 nm grade targets particulates below what a standard 0.04 µm pass can remove.
- Valve & Sensor Protection: Reduces particulate load on automated dispensing hardware.
- Extended Perfusion Stability: Supports longer unattended automated processing intervals.
Inquiry Required: The 0.01 µm ultra-filtered grade is available by request — contact support@diagnocine.com.
RNA Gel Electrophoresis
Widely used for separating RNA samples on agarose and formaldehyde-agarose (denaturing) gels, improving resolution of large RNA species above 6 kb.
Northern Blot Analysis
Utilized in the hybridization of total RNA or mRNA to membranes for downstream detection.
SDS-PAGE
Commonly used for protein electrophoresis, particularly with Bis-Tris gels, running proteins slower than MES buffer for improved resolution of larger proteins.
Western Blotting
Facilitates the transfer of proteins from gels to membranes for specific protein detection and analysis.
Culture Media Buffering
Used to regulate the acid-base balance in cell culture media, providing a suitable environment for cell growth.
UV/VIS Spectrophotometry
Used to measure absorption in spectrophotometric analyses.
