FluxMPS™ Orange Loading Buffer [6X]
FluxMPS™ Orange Loading Buffer [6X] delivers a precise pH 7.6 Tris-HCl/EDTA formulation with defined 10 mM / 60mM molarity, ultra-filtered through a quadruple-stage 0.1 µm (x2) and 0.04 µm (x2) membrane process for microchannel-safe, low-background performance in DNA and RNA electrophoresis workflows.

Engineered where standard loading buffers fail
Conventional 0.22 µm-filtered loading buffers can carry subvisible particulates, inconsistent tracking dye behavior, and unverified nuclease activity into sensitive DNA/RNA electrophoresis workflows. FluxMPS™ Orange Loading Buffer [6X] is engineered to remove those failure points at the source.
Microchannel-safe purity
Quadruple-stage 0.1 µm (x2) and 0.04 µm (x2) membrane filtration removes particulates that can interfere with fine capillary electrophoresis and lab-on-chip DNA analysis systems[1].
Precise, stable pH
Tris-HCl buffering at pH 7.6 provides a stable environment that helps maintain the integrity of DNA and RNA samples during electrophoresis.
Ultrapure-grade water
Manufactured with Ultrapure Type 1 water (18.2 MΩ·cm) consistent with USP <85> manufacturing practices.
Low background for imaging & assays
Orange G dye runs ahead of most DNA samples under 500 bp, ensuring it does not obscure visualization of DNA bands under UV or blue-light imaging.
Defined, traceable composition
Glycerol, Orange G dye, Tris-HCl, and EDTA concentrations are controlled and documented on a per-lot basis.
Customization on demand
Alternate concentrations, additional tracking dyes, different pH, and other modifications are available — contact support@diagnocine.com.
Quadruple-stage filtration system
Every lot of Orange Loading Buffer [6X] is sterile-filtered with two passes through a 0.1 µm membrane and two passes through a 0.04 µm membrane, in a sterile environment, delivering an ultrapure loading buffer for demanding molecular biology workflows.
- 1
0.1 µm Pre-filtration I
Removes large particulates and aggregates from the Tris-HCl/EDTA/glycerol/Orange G formulation, extending downstream filter life and protecting fine gel-loading applications from debris.
- 2
0.04 µm Pre-filtration II
A finer 0.04 µm membrane pass retains fine particulates and bioburden ahead of the final sterile-filtration stages.
- 3
0.1 µm Sterile-filtration I
A second 0.1 µm pass provides redundant particulate and bioburden reduction before final polishing.
- 4
0.04 µm Sterile-filtration II — Final Polish
The second 0.04 µm pass delivers the final polish in a sterile, ISO Class 5 (Class 100) fill environment. Sequential dual-membrane filtration reduces bioburden below the size of the smallest known mycoplasma organisms, reported at approximately 0.2 micron, consistent with DiagnoCine Precision's dual-membrane sterility standard[3].
Performance vs. conventional buffer
Sequential 0.1 µm (x2) and 0.04 µm (x2) membrane filtration removes finer particulates than the single-pass 0.22 µm filtration typical of standard loading buffers, supporting cleaner downstream electrophoresis, imaging, and DNA/RNA visualization.
