Description
Precision Plus Protein Dual Xtra Standards are a mixture of 12 recombinant proteins (2–250 kD), including nine blue-stained bands and three pink reference bands (2, 25, and 75 kD). These standards can be detected by fluorescence when excited at red and green wavelengths.
| Visible Band Color | Excitation | Fluorescent Band MW |
| Blue | 635 nm laser or Red LED | 15, 20, 37, 50, 100, 150, 250 kD |
| Pink | 532 nm laser or Green LED | 25, 75 kD |
| Note: For Precision Plus Protein Dual Xtra Prestained Standards the 2 kD band is not visible on fluorescent blots. | ||
