Protocols for Nucleic Acid Analysis by Nonradioactive Probes - download pdf or read online

This ebook offers an incredibly necessary selection of attempted and verified protocols for nucleic acid research that keep away from using radioisotopes. Southern (i. e. , DNA) and northern (i. e. , RNA) blotting protocols are coated intimately, from how you can isolate high quality nucleic acids from plant and animal assets, to using the widest variety of probe platforms (involving digoxigenin, biotin, fluorescein, horseradish peroxidase labeling, and colorimetric and chemiluminescent detection).

Example text

Radiograph A photographic image produced by ionizing radiation on a film or paper after passing through a material. Radiographic contrast The relative density or brightness between adjacent areas on an illuminated radiograph or a fluorescent screen or video device. Radiographic definition A measure of the sharpness of a radiographic image. Radiographic exposure The subjection of a recording medium to radiation for the purpose of producing a latent image. Radiographic exposure is commonly expressed in terms of milliampere minutes, or gigabequerel minutes.

Xrays and Gamma rays have a quality factor of 1. Radioactive Decay Decrease of activity due to radioactive disintegration. Generally expressed as half life. Radioactivity The property of certain atoms to decay and emit particulate and/or gamma radiation. Radiograph A photographic image produced by ionizing radiation on a film or paper after passing through a material. Radiographic contrast The relative density or brightness between adjacent areas on an illuminated radiograph or a fluorescent screen or video device.

Beam angle The angle between the central axis of the radiation beam and the plane of the radiographic film. Beam divergence The angle of the beam of radiation as it emerges from the X-ray tube or gamma ray source. Becquerel The unit of activity of a radioisotope. An isotope has an activity of one (1) becquerel if one (1) atom is decaying each second. Its unit symbol is Bq. Betatron PDF wurde mit FinePrint pdfFactory Pro-Prufversion erstellt. de A toroidal device in which electrons are accelerated using electromagnets to generate high energy X-rays.
