Web11 Aug 2024 · The movement of any charged species through an electric field is determined by its net charge, its molecular radius, and the magnitude of the applied field. But the problem with natively folded proteins is that neither their net charge nor their molecular radius is molecular weight dependent. WebIn electrophoresis, loading dyes perform three functions. The dyes themselves move independently from the samples, allowing users to estimate nucleic acid or protein migration. Color is imparted to the samples by loading dyes, which aids in the loading process visually.
