Protein Molecular Weight Markers
Fisher BioReagents™ EZ-Run™ Prestained Rec Protein Ladder, Fisher BioReagents
Comprised of 10 recombinant proteins covalently coupled to a blue chromophore plus 10 and 72kDa reference bands tagged with green and orange dyes, respectively
Thermo Scientific™ Spectra™ Multicolor Low Range Protein Ladder
A mixture of six proteins and synthetic peptides (1.7 to 40kDa) for use as size standards for peptides and small proteins in gel electrophoresis and Western blotting.
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.
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
Thermo Scientific™ Pierce™ Prestained Protein MW Marker
Thermo Scientific Prestained Protein Molecular Weight Marker is a mixture of six blue-stained natural proteins (20 to 120 kDa) for use as size standards in protein electrophoresis (SDS-PAGE).
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™ MagicMark™ XP Western Protein Standard
