Use Precision Plus Protein WesternC Standards as a combination standard for western blotting and fluorescence detection in SDS-PAGE. These standards contain ten Strep-tagged recombinant proteins (10–250 kD), including three pink reference bands (25, 50, and 75 kD), as well as unstained versions of the Strep-tagged recombinant proteins for molecular weight sizing after blot development.

Applications and Uses

  • Monitoring electrophoretic separation
  • Monitoring blot transfer efficiency with easy orientation via multicolor standards
  • Molecular weight sizing of proteins after blot development
  • Fluorescent blot detection of prestained bands, with blue bands visualized in the red wavelength range and pink bands in the green wavelength range
