Abstract
Disclosed are compositions and methods for proximity-mediated rolling circle amplification and for real-time detection of proximity-mediated rolling circle amplification products. Rolling circle amplification (RCA) refers to nucleic acid amplification reactions involving replication of a circular nucleic acid template to form a long strand with tandem repeats of the sequence complementary to the circular template. In proximity-mediated RCA, binding guide conjugates are brought into close proximity, generally by associating them to the same analyte or to two analytes in close proximity. The binding guide conjugates comprise a specific binding molecule and a guide oligonucleotide. The guide oligonucleotides are complementary to guide complement portions on half circle probes. The complementary sequences between the guide oligonucleotides and half circle probes allow both ends of each half circle probe to hybridize adjacent to an end of the other half circle probe and to be ligated together to form a circular nucleic acid molecule comprising the two half circle probes. This circular nucleic acid molecule can then be used as the template in RCA.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
