| Empirical formula | C30H27BrN2S2 |
| Assay | ~95% |
| Storage temperature | 2-8°C |
| Application | Stains-all is suitable for differential staining of nucleic acids and proteins as follows; RNA (bluish purple), DNA (blue) and proteins (red). As little as 3 ng (123 BP fragment) of pBR322/Hae III digest DNA and 90 ng tRNA can be detected on a polyacrylamide gel. PAGE gels are stained in the dark and then destaining by removing the gel from the staining solution and exposing it to the light from a light box until sufficient destaining has occurred. A staining solution is typically made by dissolving the dye in formamide and buffer. |
