Individual or ladder series of specific mass (kilodalton, kDa) markers for use as approximate sizing standards in protein gel electrophoresis (especially SDS-PAGE); available preformulated in loading buffer, prestained, and unstained.
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.
