| Features | Micelles of anionic surfactants contained in the running buffer bind to proteins, increasing their solubility and imparting a net negative charge to the entire complex. This allows electrophoretic separation according to molecular weight, independent of the isoelectric point (pI). The band resolution is reported to be higher than that of BN-PAGE. | When large amounts of negatively charged Coomassie Brilliant Blue (CBB) bind to proteins, their solubility is enhanced and the entire complex becomes negatively charged, enabling electrophoretic separation regardless of pI. Hydrophobic proteins bound to CBB remain stable without aggregation and are not dissociated by surfactants. In contrast, basic water-soluble proteins that do not bind CBB cannot be separated by this method. | Protein migration strongly depends on protein charge and isoelectric point. Negatively charged proteins (acidic proteins with a pI lower than the gel environment) migrate toward the anode, whereas positively charged proteins (basic proteins with a pI higher than the gel environment) migrate toward the cathode and may disappear. In some cases, proteins may precipitate during electrophoresis, resulting in smeared band patterns. | This system can be used for native electrophoresis of both proteins and DNA. In polyacrylamide gel electrophoresis, the mobility of both protein and DNA bands is increased, allowing clearer separation of low–molecular-weight bands. In particular, DNA fragments of 10–20 bp, which are typically difficult to resolve, can be clearly separated even on 15% gels. |

| In-gel Enzymatic Activity Assay | Since protein denaturation is minimized, enzymatic activity is preserved. It is widely used for measuring the activities of OXPHOS, ATP synthase, NADPH-related enzymes, HRP, and various other enzymes. | Enzymatic activity may be inhibited due to binding of CBB. In addition, staining of the gel and proteins may interfere with the detection of enzymatic activity. | As protein denaturation does not occur, enzymatic activity is preserved. However, precipitation or reverse migration may occur during electrophoresis, sometimes preventing clear band separation. | Since protein denaturation does not occur, enzymatic activity is preserved. |

| In-gel Fluorescence Assay | Since protein denaturation is minimized, fluorescence reactions are not inhibited, and absorption of fluorescent signals does not occur due to the clear background. It is used for analysis of Cy-dye–labeled proteins, GFP, YFP, and other fluorescent proteins. | Fluorescence detection may be inhibited because CBB binds to proteins. In addition, strong blue staining of the gel and proteins interferes with fluorescence detection by absorption, and fluorescence quenching of approximately 90–95% has been reported. | Since protein denaturation is minimized, fluorescence reactions are not inhibited, and absorption of fluorescent signals does not occur due to the clear background. However, precipitation or reverse migration may occur during electrophoresis, sometimes preventing clear band separation. | Since protein denaturation is minimized, fluorescence reactions are not inhibited, and absorption of fluorescent signals does not occur due to the clear background. |

| Protein complex analysis | Because a small amount of an anionic surfactant is included, unstable interactions between subunits may dissociate during electrophoresis. As a result, some protein complexes may not be separated at their intact size. | Since dissociation of complexes does not occur during electrophoresis, complexes can be separated easily even in small amounts. This method shows high correlation with chromatography (≥90%) and is widely used for analysis of OXPHOS, ATP synthase, GPCRs, membrane proteins, and other protein complexes. | Although complex dissociation does not occur during electrophoresis, precipitation or reverse migration may occur, sometimes preventing clear band separation. | Complex dissociation does not occur during electrophoresis and this system is more suitable for separation of low–molecular-weight complexes than high–molecular-weight complexes. |
