Prestained Protein Marker consists of high-purity and pre-stained recombinant proteins, which is convenient for monitoring of electrophoresis and transfer efficiency. This ready-to-load protein ladder is formulated in Laemmli buffer with 0.1% SDS, requiring no denaturation or reduction steps prior to SDS-PAGE or western blot applications.
Key Features
• 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.
Applications
1. Monitoring protein migration during SDS-polyacrylamide gel electrophoresis.
2. Monitoring protein transfer onto membranes after western blotting.
3. Sizing of proteins on SDS-polyacrylamide gels and western blots.
Component
1. Prestained Protein Marker: 4×250 μl
Storage
Store at -20°C.
