Your Ad Here	Labelling of probes The detection of homologous sequences after hybridization with the probe is like finding a needle in the haystack. Use of Labelled DNA probe for identification of homologous DNA sequencs through DNA hybridization Therefore, for the success of DNA probe assay, it is necessary to develop simple, safe and sensitive techniques for their use.
As probes transmit no signal of their own, they have to be (i) either labelled with radioactive isotopes or (ii) methods are used to couple nonradioactive signal molecules to the probes without impairing the hybridization ability of these probes. These signal molecules may include fluorescent antibodies and enzymes that produce colour changes in dyes and chemiluminescent catalysts.
