The kinetics of in situ hybridization.

چکیده
The kinetics of the cytological or in situ DNA-RNA hybridization reaction between 125-I HeLa cell 18S and 28S rRNA and the interphase nuclei of chinese hamster cells were studied. The reaction is consistent with the expected first order kinetics, and the value of the rate constant was very similar to the value obtained from analogous filter disc DNA-RNA hybridization experiments. This similarity in the rate constants and the known relationship between the rate constant and the complexity of the RNA hybridized, define conditions to optimize the in situ hybridization reaction.

Estimation of absorbed dose for radiation workers or person involved in different radiological accident is the aim of biodosimetry. Cytogenetic methods are the most current and applicable biodosimetry tools. In chronic or protracted exposure, fluorescence in situ hybridization (FISH), stable chromosomal aberration is used for estimation of absorbed dose. For precise estimation of absorbed dose,...

In situ hybridization (ISH) is a method that uses labeled complementary single strand DNA or RNA to localize specific DNA or RNA sequences in an intact cell or in a fixed tissue section. The main steps of ISH consist of: probe selection, tissue or sample preparation, pre-hybridization treatment, hybridization and washing, detection and control procedure. Probe selection is one of the important ...
