Abstract

Abstract The invention relates to a method for the synthesis of ribonucleic acid starting from deoxyribonucleic acid in which a target sequence is present. Said DNA is treated with restriction enzyme(s) followed by strand separation. Subsequently one uses one nucleic acid primer containing a promoter sequence coupled to a nucleotide sequence which corresponds to a part of the target sequence. The invention further relates to a test kit for synthesizing RNA.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 122 words
Method for the synthesis of ribonucleic acid (RNA) starting from deoxyribonucleic acid (DNA) in which a target sequence is present, by treating this DNA with one or more restriction enzymes, followed by a separation of the DNA fragment thus obtained, by which means single-strand DNA is formed, after which one nucleic acid primer containing a promoter sequence which is coupled to a nucleotide sequence which corresponds to a part of the target sequence is hybridized under suitable conditions on the corresponding single-strand DNA, after which the two nucleic acid sequences obtained in hybrid form are extended from the free 3′-end by a DNA polymerase to produce a double-strand DNA, which is then used as a matrix by RNA polymerase for synthesizing RNA.
Claim 2
Dependent Claim 122 words
Method for the synthesis of ribonucleic acid (RNA) starting from deoxyribonucleic acid (DNA) in which a target sequence is present, by treating this DNA with one or more restriction enzymes, followed by a separation of the DNA fragment thus obtained, by which means single-strand DNA is formed, after which one nucleic acid primer containing a promoter sequence which is coupled to a nucleotide sequence which corresponds to a part of the target sequence is hybridized under suitable conditions on the corresponding single-strand DNA, after which the two nucleic acid sequences obtained in hybrid form are extended from the free 3′-end by a DNA polymerase to produce a double-strand DNA, which is then used as a matrix by RNA polymerase for synthesizing RNA.
Claim 3
Dependent Claim 35 words
Method according to Claim 1, characterized in that the synthesized RNA is detected by means of gel electrophoresis under denaturing conditions followed by blotting, after which hybridization with a labelled specific oligonucleotide sequence takes place.
Claim 4
Dependent Claim 9 words
Test kit for synthesizing RNA according to Claim 1.
