The Color Prestained Protein Standard, Broad Range is a mixture of highly pure, recombinant, prestained proteins, covalently coupled with a blue chromophore, and two reference bands (one orange and one green at 72 kDa and 26 kDa, respectively), that resolves into 11 sharp bands when electrophoresed.
  • Allows approximate molecular weight determination when performing SDS-PAGE analysis.
  • Applications include verification of Western transfer efficiency on membranes and fluorescent imaging of SDS-PAGE.
  • Direct loading, additional loading buffer and heat incubation not required
  • Recombinant proteins with no detectable protease contaminating activities
  • Optimal stability for up to 24 months

 

 

The Color Prestained Protein Standard, Broad Range is a mixture of highly pure, recombinant, prestained proteins, covalently coupled with a blue chromophore, and two reference bands (one orange and one green at 72 kDa and 26 kDa, respectively), that resolves into 11 sharp bands when electrophoresed. The Color Prestained Protein Standard is designed for observing protein separation during SDS-PAGE, verification of western transfer efficiency on membranes, and for approximating the size of proteins (1-2). The Color Prestained Protein Standard may also be used in fluorescent imaging of SDS-PAGE.

Notes
  • To ensure uniform mobility, load an equal volume of 1X Reducing SDS Loading Buffer into any unused wells.
  • To maximize shelf life, store at -20°C. Guaranteed stable for 2 years when properly stored.
  • It is not necessary to pre-heat the unstained protein standard prior to loading on a gel.
  • Recommended mini-gel load: 3 μl.
  • Apparent molecular weight values for prestained proteins can be different when run on different gel types and percentages.
