Title: Detection and quantitative determination of rna and dna
Inventor: HORNES ERIK
IPC: C12Q1/6853
Filed: 1989-11-21
Abstract: Abstract Detection and Quantitative Determination of RNA and DNA      The method for the detection and/or quantitative determination of target RNA or DNA in an analyte sample includes the steps of: a)   contacting the analyte with magnetic particles carrying a single stranded 5'-attached DNA probe capable of binding to said RNA or DNA; b)   contacting the magnetic particles with an aqueous solution of a reverse transcriptase or polymerase in the presence of labelled nucleotides using the probe as a primer whereby labelled complementary single stranded DNA is formed if said RNA or DNA was present in said analyte; magnetically aggregating the magnetic particles onto a surface and removing said solution; and c)   detecting the presence or absence of said label and/or determining the amount of said label.     The chain length of complementary single stranded DNA is limited by, for example a predetermined amount of dideoxynucleotides being present at step (b) to limit chain synthesis to a predetermined average length or the probe binding to said DNA or RNA a predetermined distance from a chain terminating point of said DNA or RNA.     A kit for preforming the method is disclosed.
