Nucleobase-specific Probes [RNA Structure Analysis]
Numerous compounds are known as base-specific probes, including DMS, a small molecule probe that was first used for RNA structural analysis, CMCT, and Kethoxal. For obtaining structural information for all nucleotides using base-specific probes, multiple reagents are required.
| Probe | Primary Modification Sites | Product Number |
|---|---|---|
| DMS | Guanine N7, Adenine N1, Cytosine N3 | |
| DEPC | Adenine N7 | |
| CMCT | Guanine N1, Uracil N3 | |
| Kethoxal | Guanine N1 and N4 | - |
| DMAS-Cl | Guanine N2 | - |
| Naz | Guanine C8, Adenine C8 |
[Abbreviations]
DMS: Dimethyl Sulfate; DEPC: Diethyl Pyrocarbonate, CMCT: 1-Cyclohexyl-3-(2-morpholinoethyl)carbodiimide Metho-p-toluenesulfonate; DMAS-Cl: N,N-(Dimethylamino)dimethylchlorosilane; Naz: Nicotinoyl Azide
DMS: Dimethyl Sulfate; DEPC: Diethyl Pyrocarbonate, CMCT: 1-Cyclohexyl-3-(2-morpholinoethyl)carbodiimide Metho-p-toluenesulfonate; DMAS-Cl: N,N-(Dimethylamino)dimethylchlorosilane; Naz: Nicotinoyl Azide
Naz (Nicotinoyl Azide) is used to study the solvent accessibility of purine nucleobases in RNA with the RNA structural analysis method LASER (Light Ativated Structural Examination of RNA).
