  • Publication number: 20220098641
    Abstract: It is disclosed a method for the detection of an amplification of nucleic acids in which substantially use is made of the fact that a pre-defined nucleic acid chain (target sequence) can be multiplied/amplified in the presence of a target sequence-specific activator oligonucleotide. The target sequence-specific activator oligonucleotide causes the separation of re-synthesized complementary primer extension products by means of strand displacement, so that a new primer oligonucleotide can attach to the respective template strand. The thus formed complex of a primer oligonucleotide and a template strand can initiate a new primer extension reaction. The thus formed primer extension products in turn function as templates, so that an exponential amplification reaction results. Amplification is detected by a detection system.

  • Publication number: 20210189479
    Abstract: A method is disclosed for detecting an amplification of nucleic acids in which use is essentially made of the fact that a predefined nucleic acid chain (target sequence) can be multiplied/amplified in the presence of a target-sequence-specific activator oligonucleotide. The target-sequence-specific activator oligonucleotide brings about the separation of de-novo synthesized complementary primer elongation products by means of strand displacement, so that a new primer oligonucleotide can attach to the respective strand of the template. The complex thus formed, of a primer oligonucleotide and a template strand, can initiate a new primer elongation reaction. The primer elongation products thus formed, in turn, act again as templates, the result being an exponentially proceeding amplification reaction. In the method, a selective amplification is effected in that, for the first, second primer and activator oligonucleotide, variants are used which differ from the target sequence by at least one nucleotide.

  • Publication number: 20210071244
    Abstract: The invention relates to a method for amplification of a nucleic acid by a nucleic acid polymerase via two primers, each of which comprise a sequence segment which is bound to the target sequence and a sequence segment which does not bind to the target sequence, wherein the second cannot serve as a template for the polymerase, and two controller oligonucleotides, each of which is complementary to the primers and a segment of the sequence segment synthesized by them and serves to release the synthesized strand from the template. The controllers also comprise modified nucleotide building blocks such that they cannot serve as templates for the activity of the first template-dependent nucleic acid polymerase.

  • Publication number: 20210071243
    Abstract: The present invention relates to a method for the extension of an oligonucleotide primer with improved specificity using a specific oligonucleotide primer and a controller nucleotide, wherein the controller oligonucleotide enables sequence-specific strand opening of a double strand of extension product and template. The invention further relates to a respective kit for carrying out the method according to the invention.
