Protein Molecular Weight Markers
Invitrogen™ Mark12™ Unstained Standard
Allows the closest estimation of molecular weight of your sample protein over a wide molecular weight range.
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 High Range Protein Ladder
A mixture of eight blue-, green- and orange-stained proteins (40 to 300kDa) for use as size standards for high MW proteins in gel electrophoresis and Western blotting.
Thermo Scientific™ PageRuler™ Unstained Low Range Protein Ladder
Thermo Scientific PageRuler Unstained Low Range Protein Ladder is a mixture of eight purified proteins and peptides (3.4 to 100 kDa) for use as size standards in peptide and small-protein gel electrophoresis.
Invitrogen™ NuPAGE™ Large Protein Blotting Kit
Specifically designed for large protein analysis on NuPAGE Novex Tris-Acetate Gels under denaturing conditions
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.
