Compare the two idealized SDS-PAGE gels below. Assume they've been stained with a total protein dye such as Coomassie Blue. Which of them more accurately represents the elution profile of a 3-protein mixture loaded on a size exclusion column? Consider the idealized SDS-PAGE gel below. Assume it has been stained with a total protein dye such as Coomassie Blue. You are told that these are elution fractions from a glutathione column (following a thorough wash) and that only Protein A has a GST tag. What can you reasonably hypothesize about Protein B
