Protein Molecular Weight Markers
Cytiva Rainbow™ Molecular Weight Markers
Monitor progress of protein electrophoresis and assess transfer efficiency and molecular weight of blotted proteins without staining. Cytiva Life Sciences™ Rainbow™ Molecular Weight Markers use bright, distinctive colors to allow easier confirmation of transfer to blotting membranes and orientation.
Thermo Scientific™ Pierce™ Unstained Protein MW Marker
A mixture of seven native proteins (14.4kDa to 116kDa) for use as size standards in protein electrophoresis (SDS-PAGE).
Invitrogen™ SeeBlue™ Pre-stained Protein Standard
Allows you to easily monitor the progress of your gel run and is an excellent tool for judging Western transfer efficiency.
Thermo Scientific™ SuperSignal™ Molecular Weight Protein Ladder
Ready-to-use mix of recombinant proteins (20 to 150K) with IgG-binding sites for chemiluminescent, fluorescent, chromogenic or other detection methods.
Thermo Scientific™ PageRuler™ Unstained Low Range Protein Ladder
Thermo Scientific PageRuler Unstained Low Range Protein Ladder is a mixture of eight purified proteins and peptides (3.4 to 100 kDa) for use as size standards in peptide and small-protein gel electrophoresis.
Invitrogen™ HiMark™ Unstained Protein Standard
Designed for analysis of high molecular weight proteins on Novex™ NuPAGE™ Tris-Acetate Gels
Invitrogen™ BenchMark™ Pre-stained Protein Ladder
Standard used to monitor electrophoresis or electrophoretic transfer from gel to membrane in Western blots
Invitrogen™ Novex™ Sharp Unstained Protein Standard
Designed for accurate, easy and convenient molecular weight estimation of a wide range of molecular weight proteins during SDS-PAGE and western blotting
Novus Biologicals™ Blu10 Prestained Protein Ladder
Prestained Protein Ladder
Promega Broad Range Protein Molecular Weight Marker
10-225kDa; 9 bands; ready to load. Protein staining required for detection.
MP Biomedicals™ Pre-stained Molecular Weight Standard, Dual Color, 0.5 mL
Pre-stained Molecular Weight Standard, Dual Color is a ready-to-use three-color protein standard with 11 pre-stained proteins covering a wide range of molecular weights from 10 to 250 kDa.
Cytiva Protein and Peptide Molecular Weight Markers
Run these markers to determine the molecular weight of uncharacterized protein samples with precision. Cytiva Life Sciences™ Protein and Peptide Molecular Weight Markers work by comparing unknowns with carefully selected standards.
MP Biomedicals™ Fluorescent Protein Marker
Obtain accurate molecular weight protein standards. Skip gel staining steps and estimate protein molecular weight using UV.
