PeppermintStick Phosphoprotein Molecular Weight Standards are a mixture of phosphorylated and nonphosphorylated proteins ranging from 14.4 to 116 kDa. Separation by polyacrylamide gel electrophoresis resolves the standard mixture into two phosphorylated and four nonphosphorylated protein bands.

Applications
• Accurate protein sizing on SDS-polyacrylamide gels and western blots.
• Positive and negative controls for detection of phosphorylated proteins, such as the methods provided by our Pro-Q™ Diamond phosphoprotein gel stain
