ENZYME ACTIVITY ASSAY USING ROLLING CIRCLE AMPLIFICATION

摘要

The present invention relates to an enzyme activity assay using rolling circle amplification for verifying that a sample contains the enzyme activity in question. Thus, the present invention pertains to a method for determining the presence or absence of one or more enzyme activities involved in circularising a non-circular oligonucleotide probe in a biological sample. Furthermore, the present invention concerns liquid compositions comprising one or more oligonucleotide probes. Within the scope of the present invention is also a composition comprising a liquid composition and a tissue sample, and solid support of one or more oligonucleotides of the present invention. Disclosed is also a microfluidic device with one or more compartments for performing rolling circle amplification events, and a method for correlating one or more rolling circle amplification events. Methods for testing the efficacy of a drug, for diagnosing or prognosing a disease, for treating a disease, or for treating prophylactically a disease is furthermore disclosed.
