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™ 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 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.
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).
Thermo Scientific™ PageRuler™ Unstained Broad Range Protein Ladder
A mixture of 11 proteins (5 to 250kDa) for use as size standards in protein electrophoresis (SDS-PAGE) and Western blotting.
Thermo Scientific™ PageRuler™ Unstained Protein Ladder
Unstained mixture of 14 recombinant, highly purified proteins (10kDa to 200kDa) for use as size standards in protein electrophoresis (SDS-PAGE) and western blotting.
