autoradiogram

A scientist examines an autoradiogram in the laboratory.

Definition

1. Noun:
   • An image produced by autoradiography: An "autoradiogram" is a photographic or digital image that records the distribution of radioactive substances within a sample, typically created by placing a radioactive specimen in contact with a photographic film or a detector.

Usage Examples

• Noun:
  • The scientist examined the autoradiogram to determine where the radioactive tracer had accumulated in the tissue. (This shows the image used to locate radioactive substances.)
  • After exposing the gel to X-ray film, an autoradiogram revealed the positions of the labeled DNA fragments. (This illustrates a common application in molecular biology.)

Advanced Usage

• "to produce an autoradiogram": to create such an image through the process of autoradiography.

  • The lab technician produced an autoradiogram of the protein sample to study its binding sites. (The image was made to analyze protein interactions.)

• "quantitative autoradiogram": an autoradiogram used to measure the amount of radioactive material present.

  • A quantitative autoradiogram allowed the researchers to estimate the concentration of the radioactive compound. (This type provides numerical data.)

Variants and Related Words

• Autoradiograph (n): a synonym for autoradiogram, often used interchangeably.

  • The autoradiograph showed clear bands of radioactive DNA. (An alternative term for the same image.)

• Autoradiography (n): the technique or process of producing an autoradiogram.

  • Autoradiography is a common method in biochemistry for detecting radioactive labels. (This is the name of the method itself.)
