    摘要: Provided herein are methods of identifying a location of an analyte in a biological sample using padlock oligonucleotides and rolling circle amplification. For example, provided herein are methods for identifying a location of an analyte in a biological sample where (i) a padlock oligonucleotide hybridizes to an analyte and is ligated thereby creating a circularized padlock oligonucleotide, (ii) rolling circle amplification of the circularized padlock oligonucleotide results in generation of an amplified circularized padlock oligonucleotide, and (iii) a signal corresponding to the amplified circularized padlock oligonucleotide is detected and used to identify the location of the analyte in the biological sample. Also provided are methods for identifying whether a treatment of a biological sample facilitates the release and subsequent detection of an analyte from the biological sample using padlock oligonucleotides and rolling circle amplification.
