FluxMPS™ Denaturing Gel-Loading Buffer without Dye [4X]
An MPS-grade, formamide- and EDTA-based denaturing gel-loading buffer supplied as a 4X concentrate for ssDNA, DNA, and RNA electrophoresis. Prepared from DEPC-treated Ultrapure Type 1 water processed through DiagnoCine's quadruple-stage filtration architecture, then terminally sterile-filtered, this dye-free formulation is engineered for microchannel-safe, low-background molecular biology workflows.

Engineered where standard loading buffers fall short
Conventional 0.22 µm-filtered loading buffers, unpurified water sources, and dye-laden formulations can introduce subvisible particulate, nuclease contamination, and optical background into sensitive nucleic acid workflows. FluxMPS™ addresses each failure mode directly.
Microchannel-safe purity
Ultrapure Type 1 water base processed through a quadruple-stage filtration architecture (0.1 µm x2, 0.04 µm x2) minimizes particulate carried into downstream gel or chip-based workflows.
Verified nuclease-free
No detectable DNase or RNase activity after 18 hr incubation with plasmid DNA and ribosomal RNA at room temperature, protecting sample integrity during denaturation and loading.
Ultrapure-grade water
DEPC-treated Ultrapure Type 1 water forms the buffer base, reducing background nuclease activity before it can affect ssDNA, DNA, or RNA samples.
Dye-free, low-background formulation
Free of SDS, bromophenol blue, and xylene cyanol, leaving downstream detection, blotting, or imaging steps unobstructed by tracking dye chemistry.
Defined denaturing chemistry
Formamide denatures secondary structure in ssDNA, DNA, and RNA, while EDTA chelates Ca2+ and Mg2+ to inhibit metal-dependent nucleases during handling.
Customization on demand
Alternate concentrations, additional chemicals, compounds, proteins, supplements, or pH adjustments are available on request.
Quadruple-stage filtration system
The DEPC-treated Ultrapure Type 1 water used to prepare this buffer is processed through DiagnoCine's quadruple-stage filtration architecture — filtered through a 0.1 µm membrane twice and a 0.04 µm membrane twice — before compounding, helping prevent mycoplasma contamination during manufacturing.
-
1
0.1 µm Pre-filtration I
Removes large particulate and aggregates from the Ultrapure Type 1 water base, extending downstream filter life.
-
2
0.04 µm Pre-filtration II
Retains fine particulates and bioburden prior to buffer compounding.
-
3
0.1 µm Sterile-filtration I
Second-pass redundancy through a 0.1 µm membrane.
-
4
0.04 µm Sterile-filtration II — Final Polish
Ultimate polish of the water base prior to compounding, supporting a controlled aseptic fill.
Performance vs. conventional loading buffer
Sequential 0.1 µm and 0.04 µm filtration of the water base removes finer particulates than a single 0.22 µm pass, supporting cleaner denaturing electrophoresis workflows.
