Not intended for human or animal diagnostic or therapeutic uses. 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. 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.

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. Markers are used to monitor transfer efficiency from gel to blotting membrane. 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. LI-COR protein ladders and markers are visible on the gel during the run, so you can monitor protein migration. 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. However, because no additional stain is added during. Instead, visualization takes place after the entire gel is stained with a dye such as Coomassie. Quality Control :ĥ μl of BlueRAY Prestained Protein Ladder (PM006-0500) resolves 10 bands in 4-20% SDS-PAGE (Tris-glycine buffer) and after Western blotting to PVDF membrane.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. Unstained protein ladders are protein ladders in which the bands or polypeptides, are not prestained and therefore cannot be visualized while the gel runs. Contents :Īpproximately 0.2~0.4 mg/ml of each protein in buffer (20 mM Trisphosphate pH 7.5 at 25☌), 2% SDS, 0.2 mM Dithiothreitol, 3.6 M Urea, and 15% (v/v) glycerol.
