100 films/box (interleaved)

Autoradiography or Chemiluminescence

• Double emulsion, very low background, blue tinted based film
• Produces sharp and clear, publishable auto-radiographs without graininess and background fogging associated with clear-based film
• This film can be used with all types of labeled samples with excellent signal, even with low levels of radioactivity

Especially suited for exposure of protein experiments and DNA sequencing gels, this film is routinely used for Western Blotting, Sequencing, Chemiluminescent Autoradiography (ecl), and Gel Shift Analysis.

The method and length of exposure depends on the type and the amount of radio-isotope used in the sample. For instance, samples labeled with high energy, ?-particle-emitting isotopes sucas ¹²⁵I , ³²P , ³⁵S may be exposed directly or with intensifying screens. Normal developing temperature is 90-93 degrees F. Processing is rapid, complete in approximately 90 seconds (varies/test). This film is for use with calcium tungstate and blue emitting screens.
