M. Kubalakova et al., A COMBINED PRINS-FISH TECHNIQUE FOR SIMULTANEOUS LOCALIZATION OF DNA-SEQUENCES ON PLANT CHROMOSOMES, Biologia plantarum, 41(2), 1998, pp. 293-296
A novel approach for simultaneous localization of two DNA sequences on
plant chromosomes is described. The approach is based on a combined u
se of primed in situ DNA labelling (PRINS) with fluorescent in situ hy
bridization (FISH). Traditionally, this has been done using FISH with
two probes labelled by two different marker molecules. Compared to thi
s method, the combined PRINS-FISH procedure is faster. Furthermore, be
cause one of the DNA sequences is localized by PRINS with specific pri
mers, only one labelled probe is needed.
