PROTEIN STANDARD

摘要

Disclosed herein is a protein standard for gel electrophoresis. The standard may be detected using multiple modalities. These modalities include, for example, observation of color or fluorescence arising from dyes, porphyrins, or haloalkylated tryptophan residues covalently linked to proteins of the standard; or detection of fluorescence or chemiluminescence arising from antibodies or other binding partners bound to proteins of the standard through polypeptide epitopes or affinity tags. The protein standard comprises multiple protein sets, each set corresponding to a different gel band, and proteins within a set may be detectable with one or more modalities.
