Precision Plus Protein Dual Xtra Prestained Protein Standards (500 µl)

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.
