Spectra and PageRuler Protein Molecular Weight Ladders

Protein Molecular Weight Markers

The Thermo Scientific Spectra Multicolor and PageRuler Protein Ladders are mixtures of recombinant proteins in various size ranges for use as size standards in protein electrophoresis (SDS-PAGE) and Western blotting. Spectra Multicolor Protein Ladders have 4 colors of protein bands, while the PageRuler Ladders are available in multi-color, single color and unstained versions.

SuperSignal Molecular Weight Protein Standards

Protein Electrophoresis and Staining

Thermo Scientific SuperSignal Molecular Weight Protein Standards (20K to 150K) are a ready-to-use mix of recombinant proteins with IgG-binding sites that provide reliable and proportional band intensities in stained gels and immunoblots developed with chemiluminescent, fluorescent, chromogenic or other detection systems.
