Abstract: Method of the latex hybridization analysis has been developed: after hybridization of NA-target with biotinylated probe visualization of hybrids was carried out using latex particles, containing fluorescent dye pyronin G and coated with streptavidin. Due to in-capsulation of the fluorescent dye in polymer particles sensitivity of the analysis was increased by several orders of magnitude in comparison with methods, using fluores-cently labelled probes. Possessing a number of advantages, the method yields to none of any other methods of NA hybridization analysis in sensitivity.
