Additional data should be considered for a more accurate adjustment.Ġ.2~0.4 mg/ml of each band of protein is stored in a mixture of solution that contains: 20 mM Trisphosphate at pH 7.5, 2% SDS, 0.2 mM Dithiothreitol, 3.6 M Urea, and 15% (v/v) Glycerol.ĥμl of IRIS9 Prestained Protein Ladder (PM009) resolves 9 bands in 4-20% SDS-PAGE (Tris-glycine buffer) and after Western blotting to PVDF membrane. Note: The molecular weight of each protein (kDa) was measured against an unstained protein ladder in every electrophoresis condition. 2.5 μl per well for general Western transferring. Refer to the IRIS9 Prestained Protein Ladder patterns in various electrophoresis conditions:ģ μl or 5 μl per loading for clear visualization during electrophoresis on 15-well or 10-well mini-gel, respectively. Guide for Molecular Weight Estimation (kDa) The EliteTM Tri-color Protein Ladder is designed for monitoring protein separation during SDS-polyacrylamide gel electrophores is, verification of Western. Sizing of proteins on SDS-polyacrylamide gels and Western blots. The IRIS9 Prestained Protein Ladder keeps track of the size and separation of proteins during SDS-polyacrylamide gel electrophoresis, approximating the target protein size and validating the Western transfer efficiency on PVDF, nylon, or nitrocellulose membranes. The markers are designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency and for. Monitoring of protein transfer onto membranes during Western blotting. The 9 recombinant proteins are covalently coupled with blue chromophore, while 2 red bands at 70 kDa and 30 kDa, a green band at 15 kDa and a newly designed peacock green band at 60 kDa serve as reference bands. Thermo Scientific PageRuler Prestained Protein Ladder is a mixture of 10 blue. The protein ladder is supplied in a ready-to-use format for direct loading onto gels no need to heat, reduce. Find prestained ladders compatible for western blotting.Product Overview. The IRIS9 Prestained Protein Ladder is a combination of 9 pre-stained proteins with molecular weights from 15 to 180 kDa. Thermo Scientific Spectra Multicolor Broad Range Protein Ladder is a 4-color (blue, orange, green, pink) protein standard containing 10 prestained proteins (10 to 260 kDa) for use in gel electrophoresis and western blotting.
