The protein ladder is supplied in a ready-to-use format for direct loading onto gels no need to heat, reduce, or add. StrepTactin is covered by German patent application P 19641876.3. Thermo Scientific PageRuler Prestained Protein Ladder is a mixture of 10 blue-, orange-, and green-stained proteins (10 to 180 kDa) for use as size standards in protein electrophoresis (SDS-PAGE) and western blotting. Compatible with chemiluminescent substrates and fluorescent secondary antibodies (not recommended for antibodies labeled with fluors in the 500–550 nm channel). Strep-tag technology for western blot detection is covered by US patent 5,506,121 and by UK patent 2,272,698.
Western blotting: detection of the nine unstained bands via the detection method used for the target protein. The protein standard 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 › During this process, the membrane and gel are placed together, with filter paper between two electrodes. The MagicMark XP Standard is compatible with most western kits and substrates (chemiluminescent, chromogenic, and fluorescent). The most common method of transfer in western blotting is electrophoretic transfer, where an electric field is used to elute proteins from gels and transfer them to membranes. The IgG binding site binds the primary or secondary antibody used for detection of the target protein, allowing direct visualization of the standard on the western blot. 1-D and 2-D protein electrophoresis equipment and reagents including Mini-PROTEAN TGX Precast Gels with stain-free technology, electrophoresis and western blotting cells, handcast gel reagents, membranes, premixed buffers and reagents, and protein electrophoresis standards. IEF standards: use 5 µl per mini gel for Coomassie staining or 0.5 µl for silver staining to yield 50 or 500 applications, respectively.MagicMark XP Western Protein Standard consists of nine recombinant proteins (20–220 kDa), each of which contains an IgG binding site. Life Science Group General Protocol for Western Blotting Protein separation by gel electrophoresis 1. Western blotting: detection of the nine unstained bands via the. The protein standard 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. A western blot of a Bolt gel shows clean, sharp protein signals. The MagicMark XP Standard is compatible with most western kits and substrates (chemiluminescent, chromogenic, and fluorescent). Storage : Stable for up to 2 weeks at 25☌. Bio-Rad protein ladders have been formulated and combined for use as molecular. Quality Control : Under suggested conditions, Unveil Unstained Protein Ladder resolves 12 major bands in 4-12Bis- Tris Gel (MES buffer) and after Western blotting to the nitrocellulose membrane. Whatever your needs for protein electrophoresis and western blotting. Bio rad western blot ladder plus#
* 2-D standards: use 2.5 µl per mini gel for Coomassie staining (200 applications) or 0.5–2.5 µl for silver staining (up to 1,000 applications) use 1.0–5.0 µl for full-length gels (16–20 cm) to yield 100 or up to 500 applications, respectively. Bulletin 6376 Ver C US/EG 17-0657 05 Web. Bolt Bis-Tris Plus mini gels help provide better western blotting results. 20 mM Tris-phosphate (pH 7.5 at 25☌), 2 SDS, 0.2 mM Dithiothreitol, 3.6 M Urea, and 15 (v/v) Glycerol. 2-D SDS-PAGE protein standards provide calibrated references for protein pI and molecular weight in the second dimension. IEF and 2D protein standards are a mixture of native proteins with isoelectric points (pI) ranging from 4.45 to 9.6, providing reproducible pI calibration in native PAGE or agarose IEF gels.
