This prestained protein MW marker is designed for monitoring the progress of SDS-polyacrylamide gel electrophoresis, for assessing transfer efficiency onto PVDF, nylon and nitrocellulose membranes, and for estimating the approximate size of separated proteins that have been made visible with gel stains or Western blot detection reagents. The Spectra Multicolor High Range Protein Ladder is ready to use: no heating, further dilution or addition of a reducing agent is required.


Features:

  • Size range—eight proteins spanning 40 to 300kDa
  • Multicolor—three different colors for unambiguous band-size assignment
  • Ready-to-use—supplied in a loading buffer for direct loading on gels; no need to boil
  • Sharp bands—color-coded bands of similar intensity for easy visualization
  • Quality tested—each lot evaluated by SDS-PAGE and Western blotting
  • Membrane-compatible—colored bands transfer to membranes for Western blotting
