#WHAT IS PROTEIN LADDER WESTERN BLOT VERIFICATION#

The apparent molecular weight (kDa) of each protein has been determined by calibration against unstained protein standards supplemental data should be considered for more accurate adjustment in different electrophoresis conditions. Detectable via chemiluminescence (using film, or charge-coupled device (CCD)-based camera. A dual view marker containing three visible bands of different colours to monitor migration and transfer and tagged proteins.

Under suggested conditions, Unveil Unstained Protein Ladder resolves 12 major bands in 4-12%Bis- Tris Gel(MES buffer) and after Western blotting to the nitrocellulose membrane. Opal Prestained Protein Standard 10-245kDa is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western. Protein molecular weight markers typically used polyacrylamide gel electrophoresis and Western blotting. The ladder is supplied in the gel loading buffer and is ready to use.Ģ0 mM Tris-phosphate(pH 7.5 at 25☌), 2 % SDS, 0.2 mM Dithiothreitol, 3.6 M Urea, and 15 % (v/v) Glycerol. The ladder contains one orange reference band at 70 kDa and one green band at 10 kDa. The Unveil Unstained Protein Ladder is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis and verifying Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins. The PageRuler Prestained Protein Ladder is a mixture of ten (10) blue-, orange- and green-stained proteins (10 to 180 kDa) for use in protein electrophoresis (SDS-PAGE) and western blotting. The proteins resolve into clearly identifiable bands when separated on the SDS-PAGE gel (MES buffer), with the intensified 25kDa and 85kDa protein bands serving as the two reference bands. Protein ladders or molecular weight markers are among the most commonly used reagents in biochemistry experiments. The Unveil Unstained Protein Ladder is a mixture of 12 unstained recombinant proteins covering a wide range of molecular weights from 10 to 200 kDa.
