Protein Ladders Guide / Pre-Stained Ladders
Pre-stained protein markers are indispensable tools in protein electrophoresis, offering visual guidance and reliable standards for accurate protein analysis. These markers contain proteins of known molecular weights, covalently linked to coloured chromophores, allowing researchers to monitor electrophoresis in real time and estimate protein sizes effortlessly.
Applications:
- Visualisation of Protein Migration: Coloured bands allow real-time tracking during SDS-PAGE.
- Verification of Protein Transfer: Visible bands confirm efficient protein transfer during Western blotting.
- Protein Sizing: Serve as reliable molecular weight references for gels and blots.
