Technique used to visualize DNA that is labeled with radioactivity. It can be used to determine the presence or absence of certain DNA fragments and the length or number of DNA molecules.

A method used to locate radioisotope-labeled materials which have been separated in gels or are present in blots. The location of the radiolabeled material is determined by overlaying the test material with a photographic film that is sensitive to the radioisotope.

3/4 A method used to determine the position of a radiochemical in a sample by the interaction of its emission with a photographic (X-ray) film.

during the polymerase reaction, a small concentration of radioactive nucleotide is added. After the gel is run it is used to expose X-ray film. When the film is developed an image of the radioactive DNA strands can be seen.

A process by which radioactive materials, often though not exclusively incorporated into cell structures, are located by exposure to a photographic emulsion forming a pattern on the film corresponding to the location of the radioactive compounds within the cell. A technique in which radioactive molecules make their location known by exposing photographic films or emulsions.

Neuroanatomical method using radioactivity that is incorporated intoneurons.

producing a radiograph by means of the radiation emitted from the specimen being photographed

A photographic image produced exposing photographic film to a radiolabeled molecule (e.g. DNA, RNA, or protein). The emissions from the radioactive label expose the photographic film.

Detection of radioactive material by exposure to X-ray film. The radioactive object produces an image of itself on a photographic film. The image is called an autoraiograph or autoraiogram.

Detection of radioactively labelled molecules with X-ray film.

Technique for visualizing radioactive molecules in a sample (e.g., a tissue section or electrophoretic gel) by exposing a photographic film or emulsion to the sample. The exposed film is called an autoradiogram or autoradiograph. ( Figure 3-45)

Technique in which a radioactive object produces an image of itself on a photographic film. The image is called an autoradiograph or autoradiogram.

A technique that uses x-ray film to detect radiolabeled molecules following separation by gel electophoresis. Recently autoradiographs have been supplanted by nonradioactive methods based on the detection of chemiluminescence.

method to detect radioactively labeled molecules as an image on a photographic emulsion.

ARG, ®Ä®g¦Û1/4v,¡@ A technique that uses X- ray film to visualize radioactively labeled molecules or fragments of molecules; used in analyzing length and number of DNA fragments after they are separated by gel electrophoresis.

Method of laying an x-ray film on radioactive material in order to detect radioactive components. After development, radioactive combinations are recognised on the film since they appear in black. The resulting picture is called autoradiogram or autoradiograph.

A process in which radioactive materials are incorporated into cell structures, which are then placed next to a film or photographic emulsion, thus forming a pattern on the film corresponding to the location of the radioactive compounds within the cell.

Neuroanatomical method using radioactivity that is incorporated into neurons.

A method for detecting radiolabeled molecules using X-ray film. It is typically done after gel electrophoresis.

A technique for imaging an object which has been radiolabeled, by exposing a photographic film to the object itself. Used to detect the location of transferred DNA fragments on a membrane (such as Biodyne® or BioTraceâ„¢ membranes) which have hybridized with radiolabeled probes. The photographic image generated by this process is called an Autoradiogram. Recently the same procedures have been used to detect chemiluminescent probes.

The method of detecting molecules or molecular fragments which uses a radioactive label within the molecule of interest. The location of the radiolabel or "tag" is detected with X-ray film.

Detection of radioactively labelled molecules on an X-ray film.
