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
Green 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.
