- 5′ iso-dC and iso-dG prevents reverse-transcriptase to reach the end
of the TSO, and therefore blocks concatenation
- ([[Kapteyn et al., 2010|biblio/20598146]]).
+ ([[Kapteyn et al., 2010|biblio/20598146]]). This was also used in
+ FFPEcap-seq ([[Vahrenkamp and coll., 2019|biblio/31649055]]).
### Effect of TSO concentration
concentration: 1 mM each. [[Pinto & Lindblad (2010)|biblio/19837043]] also
used manganese.
- - [[Lee et al (2017)|biblio/28327113]] increased the efficiency of template
+ - [[Lee and coll. (2017)|biblio/28327113]] increased the efficiency of template
switching non-capped molecules by increasing dNTPs to 2 mM and
Mg<sup>2+</sup> to 9 mM.
+ - [[Vahrenkamp and coll. (2019)|biblio/31649055]] reported that addition of
+ 1 mM manganese increases the formation of TSO concatenates and the fraction
+ of reads aliging to ribosomal sequences.
