S1 mapping is used to locate the 5’- or 3’-ends of RNAs and to quantify the amount of a given RNA in cells at a given time.

#Unit 13. Methods in Biology

The principle behind the S1 mapping method is to label a single stranded DNA probe that can hybridize only to the transcript of interest.

#Unit 13. Methods in Biology

The probe must span the sequence where the transcript starts or ends. After hybridizing the probe to the transcript, one applies S1 nuclease, which degrades only single-stranded DNA and RNA.
