Rolling circle amplification-based colorimetric assay method for target nucleic acids or proteins
ActiveCN102586450AReduce usageEasy to operateMicrobiological testing/measurementBiological testingMicroorganismMagnetic bead
The invention relates to a rolling circle amplification-based colorimetric assay method for target nucleic acids or proteins. The method mainly utilizes the hybridization between nucleic acids and antigen-antibody binding to indirectly fix the target nucleic acids or proteins to be assayed onto magnetic beads, rolling circles are added, a rolling circle primer on hybrid is utilized to carry out constant-temperature rolling circle amplification, and finally, the chromogenic reaction of nanogold is utilized to assay constant-temperature amplified macromolecular product in order to achieve the purpose of relatively assaying the target nucleic acids and proteins. By integrating rolling circle amplification and the chromogenic reaction of nanogold, the method not only amplifies a large quantity of micro-sample signals, but also realizes the rapid, visual assay of results, avoids the usage of a PCR (Polymerase Chain Reaction) instrument and other expensive instruments, and decreases the requirement on the experimental hardware condition.
