MagicMark XP Western Protein Standard from Invitrogen

Direct visualization of molecular weight standard bands on western blots with the commonly used immunodetection methods, including alkaline-phosphatase and horseradish peroxidase systems-no extra reagents and steps needed

• Intense protein standard bands that are captured directly on x-ray film or imaging systems-eliminates misalignment or mismarking of standard bands (Figures 1A and 1C)
• Sharp standard bands are visualized with your target protein on the membrane using chromogenic detection--no more faded bands on blots (Figure 1B)
• Clear bands in even increments-nine bands from 20-220 kDa on MagicMark XP Standard and eight bands from 20-120 kDa on MagicMark Standard
• Convenient, ready-to-use format--no mixing, reducing, heating, or diluting
• Clear bands are visualized with Coomassie stain on SDS-PAGE gel (Figure 2)--versatile for different applications
