In a pulse-chase procedure, a shorter chase time allows for detection of labeled molecules that are closer to the synthesis site. A longer chase time allows for detection of labeled molecules that have been transported farther away from the synthesis site. Therefore, radioactively labeled proteins would be farther from the synthesis site if the chase is longer.
