Protein Molecular Weight Markers
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.
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™ 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
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.
