Description
| Application | Naphthol Blue Black stain is designed for rapid staining of protein bands on nitrocellulose membranes (Western blots).1 Blots are stained for 1 min and then destained for 30 minutes in 25% (v/v) isopropanol, 10% (v/v) acetic acid. Used to detect proteins in the lower microgram range with a clear background. Naphthol Blue Black can also be used for staining PAGE gels.2 |
| Reconstitution | After dilution with deionized water to a final volume of 500 ml, solution will contain 0.1% (w/v) amido black, 25% (v/v) isopropanol and 10% (v/v) acetic acid. |
