Gel Retardation Assay Bundle
Complete consumable bundle for agarose gel retardation screening of LNP encapsulation — the fastest low-cost check that RNA is packed.
Ships with certificate of analysis
For Research Use OnlyOverview
What it tells you
In gel retardation (electrophoretic mobility shift) analysis, intact LNPs are too large to migrate and stay near the well, while free RNA migrates into the gel. Comparing band position and intensity gives a rapid, visual answer to the first question of every formulation run: is the RNA actually packed?
The result is qualitative to semi-quantitative — ideal for early-stage screening, protocol optimization and teaching labs. When you need a number, graduate to the RiboGreen-based Encapsulation Efficiency Assay Kit.
