The basic S1 nuclease mapping technique consists of hybridizing a labeled DNA probe that partially overlaps a RNA species of interest to that RNA species and ...
Nuclease-$1 mapping is used to map the locations of the ends of RNA mole- cules and of any splice points within them in relation to specific sites (e.g.,.
S1 nuclease mapping is mainly used to map transcription start sites accurately (to be described in this chapter), this method can also be used to map intron- ...
The method can be used to quantify RNAs, to map the positions of introns and to identify the locations of 5′ and 3′ ends of mRNAs on cloned DNA templates.
The first step in mapping the transcriptional start site by S1 nuclease treatment is to clone the upstream region of the gene into an M13 vector. Next, single- ...
