Western protein ladder12/22/2023 ![]() ![]() Monitoring of electrophoresis process and Western transfer efficiency. BenchMark Protein Ladder consists of 15 unstained recombinant proteins ranging in molecular weight from 10 to 220 kDa. Compatible with chemiluminescent substrates and fluorescent secondary antibodies (not recommended for antibodies labeled with fluors in the 500–550 nm channel). Approximate protein molecular weight determination on denaturing gels. 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 › The MagicMark XP Standard is compatible with most western kits and substrates (chemiluminescent, chromogenic, and fluorescent). 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. 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 IRIS11 Prestained Protein Ladder (PMI11) resolves 11 bands in 4-20% SDS-PAGE (Tris-glycine buffer) and after Western blotting to PVDF membrane.MagicMark XP Western Protein Standard consists of nine recombinant proteins (20–220 kDa), each of which contains an IgG binding site. A three-color protein ladder that allows you to visually monitor protein separation during SDS-PAGE or protein transfer to membranes for western blotting. The H-XStable Prestained Protein Ladder is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western. 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. The protein marker is supplied in a ready-to. Refer to the IRIS11 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. proteins (10 to 180 kDa) for use as size standards in protein electrophoresis (SDS-PAGE) and western blotting. Guide for Molecular Weight Estimation (kDa) The IRIS11 Prestained Protein Ladder keeps track of the size and separation of proteins during SDS-polyacrylamide gel electroph oresis, approximating the target protein size and validating the Western transfer efficiency on PVDF, nylon, or nitrocellulose membranes. NuPAGE Bis-Tris 8, 10, 12, 412 1.5 to 300 kDa 12 months 3550 min Separation of small- to medium-sized proteins. Ideal for Western blot transfer and analysis, and all techniques in which protein integrity is crucial. When choosing the right pre-stained protein ladder, the most important choice is based on the size of your protein of interest. The WesternSure chemiluminescent protein ladder is the only pre-stained, multi-colored protein ladder for both film and digital chemiluminescence detection. The 10-180kDa Prestained Protein Ladder is designed for monitoring protein separated during SDS-polyacrylamide gel electrophoresis, verification of Western. Wedge well design can accommodate large sample volumes. The gel used was a 10 Tris-Bis gel from life-technologies. Good separation in SDS-PAGE and nice transfer onto nitrocellulose membrane. Very easy to use protein ladder in the range from 10-180 kDa. ![]() The 11 recombinant proteins are covalently coupled with blue chromophore, while 2 red bands at 70 kDa and 260 kDa, a green band at 15 kDa and a newly designed peacock green band at 60 kDa serve as reference bands. Neutral pH environment minimizes protein modifications. Western blot - Prestained Protein Ladder Mid-range molecular weight (10 - 180 kDa) (ab116027) This image is courtesy of an anonymous Abreview. Three different chromophores are bound to the proteins, producing a brightly colored ladder. ladder helps to track gel-to-membrane transfer during western blot. The Thermo Scientific PageRuler Prestained Protein Ladder is a prestained mixture of ten recombinant proteins ranging from 10 kDa to 180 kDa. The IRIS11 Prestained Protein Ladder is a combination of 11 pre-stained proteins with molecular weights from 3 to 260 kDa. protein ladders, unstained protein ladders and prestained protein ladders. ![]()
