The Penn State ladder containing 10, 15, 20, 30, 40, 50. Protein Ladders and Standards Precast Protein Gels Protein Electrophoresis and Blotting Products Supporting Documents and Resources. 3 μl or 5 μl per loading for clear visualization during electrophoresis on 15-well or 10-well mini-gel, respectively. Use of Penn State protein ladder in Western blots.The ladder is supplied in the gel loading buffer and is ready to use. There are two categories of commercially available protein ladders, unstained protein ladders and prestained protein ladders. After transferring the protein bands onto the blot paper, stain the paper with Ponceau-S. Is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis and verifying Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and forĪpproximating the size of proteins. If you want to do with unstained ladder yet, I recommend to do all steps of western blot just routinely do. Will SMOBIOs Protein Markers/Ladder be washed out during Western blotting process SMOBIOs Protein Markers. Proteins are covalently coupled with aīlue chromophore except for three reference bands (two orange bands at 30 kDa and 270 kDa and one green band at 52 kDa) when separated on SDS-PAGE (Tris-glycine buffer). stained protein in the SDS-PAGE analysis. Compatible with chemiluminescent substrates and fluorescent secondary antibodies.The GENE’s Protein Ladder is a three-color protein standard with 10 pre-stained proteins covering a wide range of molecular weights from 6.5 to 270 kDa. The ladder is visualized by SDS-PAGE using coomassie or silver stains or detected in Western blots with protein stains. 26634 Spectra Multicolor Broad Range Protein Ladder, 2 × 250µL. 26632 PageRuler Low Range Unstained Protein Ladder, 2 × 250µL. 26630 PageRuler Broad Range Unstained Protein Ladder, 2 × 250µL. These protein standards and ladders are consistent from lot to lot and are strictly. The Thermo ScientificTM PageRulerTM Unstained Protein Ladder consists of a unstained mixture of 14 recombinant, highly purified proteins ranging from 10 kDa to 200 kDa. 26619 PageRuler Plus Prestained Protein Ladder, 2 × 250µL. Each protein standard or ladder is supplied in a ready-to-use format, eliminating the need to reduce, pre-mix, or add loading dyes. Western blotting: detection of the two unstained bands via the detection method used for the target protein. Choose from a variety of protein ladders (molecular weight markers) for protein electrophoresis and western blotting applications.Western blot confirmation-detect the two unstained proteins (30 kDa and 80 kDa) using the detection system for the target protein.Each protein in the ladder contains an integral Strep-tag. Fluorescent visualization-detect the 10 stained proteins using the 670 nm red laser or 700 nm channel of a fluorescence imager purified, unstained proteins for use as size standards in SDS-PAGE and western blotting.The protein ladder is supplied in a ready-to-use format for direct loading onto gels no need to heat, reduce, or add sample buffer prior to use.Ĭompare and view all other protein standards and ladders › This electrophoresis protein marker is stable for up to two weeks at 25 C and for up to 3 months at 4 C. IBright Prestained Protein Ladder contains twelve recombinant proteins, ten (11 to 250 kDa) that are blue-stained and fluor-labeled for direct and near-IR fluorescent visualization and protein sizing, and two (30 kDa and 80 kDa) that are unstained and contain IgG binding sites to bind the primary and secondary antibodies used for chemiluminescent and fluorescent detection of the target protein.
