WebAs a protein is made, it passes step by step through a shipping "decision tree." At each stage, the protein is checked for molecular tags to see if it needs to be re-routed to a different pathway or destination. Diagram based on similar diagram in Alberts et al. ^1 1. The first major branch point comes shortly after translation starts. WebProteins are commonly separated using polyacrylamide gel electrophoresis (PAGE) to characterize individual proteins in a complex sample or to examine multiple proteins within a single sample. When combined with western blotting, PAGE is a powerful analytical tool providing information on the mass, charge, purity or presence of a protein. imani williams singer
