Protein Molecular Weight Markers
Thermo Scientific™ PageRuler™ Prestained Protein Ladder, 10 to 180 kDa
Thermo Scientific PageRuler Prestained Protein Ladder is a mixture of 10 blue-, orange-, and green-stained proteins (10 to 180 kDa) for use as size standards in protein electrophoresis (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.
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.
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™ Plus Prestained Protein Ladder, 10 to 250 kDa
Thermo Scientific™ PageRuler Plus Prestained Protein Ladder is a mixture of nine (9) blue-, orange- and green-stained proteins (10 to 250 kDa) for use as size standards in protein electrophoresis (SDS-PAGE) and Western blotting.
Thermo Scientific™ Spectra™ Multicolor Broad Range Protein Ladder
Thermo Scientific™ Spectra Multicolor Broad Range Protein Ladder is a 4-color protein standard containing 10 prestained proteins (10 to 260 kDa) for use as size standards in gel electrophoresis and Western blotting.
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™ Spectra™ Multicolor Low Range Protein Ladder
