[The development of kit for hybridization extraction of DNA and RNA of agents of hemotransmissive infections from serum and blood plasma].

ABSTRACT

To decrease dependence of effectiveness of isolation of nucleic acids of composition and amount of applied sample a kit was developed for hybridization extraction of DNA HBV RNA HCV and RNA HIV from blood serum in two formats--using up to 250 mkl and up to 1 ml of sample. This kit, in complex with kits for detection using polymerase chain reaction technique in real-time, forms a test characterized by high analytical sensitivity i.e. HBV50 copies per ml, HCV37.5 copies per ml, HIV 13 copies per ml. The developed kit for extraction of target nucleic acids permits to get rid of total DNA and inhibited effect of heparin. It can be adapted for application wit factors B and automated stations of sample preparation.
