The 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).

Applications and Uses

Choose Precision Plus Protein Dual Xtra standards for SDS-PAGE:

  • Monitoring electrophoretic separation
  • Molecular weight sizing
  • Monitoring blot transfer efficiency with easy orientation via multicolor standards
  • Fluorescent blot detection, with blue bands visualized in the red wavelength range and pink bands in the green wavelength range (prepare a 1:10 dilution of the Dual Xtra standard and load 5 µl per well)
  • Note: Bands between 5 kD and 250 kD are only visible in fluorescent blots
