PeppermintStick™ Phosphoprotein Molecular Weight Standards (Invitrogen™)

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.

• 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
