Abstract:
Disclosed herein are compositions and methods for determining a presence or abundance of an analyte in a biological sample. The methods disclosed herein include: (a) providing a biological sample on a substrate comprising a plurality of capture probes, wherein a capture probe of the plurality of capture probes comprises a capture domain; (b) releasing the analyte from the biological sample; (c) affixing a stretching moiety to the analyte; (d) hybridizing the analyte to the capture domain of the capture probe; (e) applying a stretching force to the stretching moiety, thereby elongating the analyte hybridized to the capture domain; and (f) generating an extended capture probe using the analyte as a template.
