Protein Standards

GenScript offers a wide selection of Protein molecular weight standards for SDS-PAGE and Western blot, including prestained, unstained, peptide, Western-viewable, and other standards. The Pre-stained Protein Standards consist of colored bands for easy identification and allow you to monitor the progress of an electrophoretic run. The Unstained Protein Standards provide bands that are unmodified by the presence of dye, for accurate molecular weight estimation of SDS-PAGE. Available in convenient package sizes, all standards have undergone stringent QC to assure consistent performance to provide the sharper bands in the broader molelular weight range available.
