1. to produce an autoradiograph of; to create a photographic record using autoradiography
Usage: technical; scientific

Examples

• The scientist examined the autoradiograph to identify where the radioactive isotope had accumulated in the tissue sample.
• Researchers used autoradiography to autoradiograph the DNA fragments and determine their molecular weight.
• The autoradiograph revealed the distribution of the labeled compound throughout the organism.
• By autoradiographing the protein sample, they could track the movement of the radioactive marker.
• The dark spots on the autoradiograph indicated areas of high radioactive concentration.
• Modern laboratories often use digital imaging instead of traditional autoradiograph plates.
