Tīmeklis2024. gada 20. jūl. · For radioactive probes, hybrids are detected auto-radiographically. For nonradioactive probes, the signal is generated directly or indirectly by labeled probes and detected by microscopy. Evaluation of ISH results by bright-field microscopy is preferred for most routine applications because the preparations are permanent. …
TīmeklisCäsium 137 hat mit 30,19 Jahren, bezogen auf eine menschliche Lebensspanne, eine lange Halbwertzeit, während sich beispielsweise die Aktivität von Jod-131 innerhalb von 8 Tagen durch radioaktiven Zerfall halbiert. Aus strahlenbiologischer Sicht ist außer Cs-137 auch Cäsium-134, von allerdings geringerer Bedeutung. Tīmeklis2024. gada 9. apr. · Then a hybridization solution containing a small amount of single-stranded probe DNA that is complementary in sequence to a target molecule on the membrane. This probe DNA is labeled using fluorescent or radioactive molecules, and if the hybridization is performed properly, the probe DNA will form a stable duplex …
TīmeklisThe DNA probes may be labelled using different methods, namely nick translation, random primed labelling or by polymerase chain reaction. The RNA probes are labelled by in vitro transcription. The labels can be either radioactive or non-radioactive. If radioactive probes are used, then the detection is done through autoradiography. TīmeklisThe initially developed protocols applied radioactive probes labeled with, radioactive isotopes for detection purposes via implementation of autoradiography procedures. In this process using the pattern of decay emissions radiated from a radioactive material is applied to produce an image on an x-ray film which can also be made available as a ...
