In general, different TSOs can be used including TSOs with 5′ modifications, such as biotin, isomeric bases or abasic spacers. We recommend a TSO with rGrGrG at the 3′ end for efficient template switching but various types/sequences of TSOs are compatible with the Template Switching RT Enzyme Mix.

The simple version of a TS Oligo is a DNA oligo sequence that carries 3 riboguanosines rGrGrG at its 3 end 1 The complementarity between these consecutive rG bases and the 3 dC extension of the cDNA molecule empowers the subsequent template switching 5 A more recent study suggested replacing the 3 most rG with a locked nucleic

CDNA Synthesis And Amplification Protocol Using The Template NEB

Step 3 Template switch oligo binds the CCC overhang Step 4 Reverse transcriptase switches templates and continues polymerization using the template switch oligo as the template Steps 5 7 The single stranded cDNA product of reverse transcription becomes the template for second strand synthesis primed by the universal PCR forward primer

Alternative polyadenylation is commonly examined using cDNA sequencing which is known to be affected by template switching artifacts However the effects of such template switching artifacts on alternative polyadenylation are generally disregarded while alternative polyadenylation artifacts are attributed to internal priming Here we analyzed both long read cDNA sequencing and direct RNA

Amplification Of CDNA Ends Based On Template Switching Effect And Step

The template switching PCR TS PCR method of cDNA synthesis represents one of the most straightforward approaches to generating full length cDNA for sequencing efforts However when applied to very small RNA samples such as those obtained from tens or hundreds of cells this approach leads to high background and low cDNA yield due to concatamerization of the TS oligo

Reverse transcriptases RTs can switch template strands during complementary DNA synthesis enabling them to join discontinuous nucleic acid sequences Template switching TS plays crucial roles in retroviral replication and recombination is used for adapter addition in RNA Seq and may contribute to retroelement fitness by increasing evolutionary diversity and enabling continuous

When base pairing occurs between the template-switch oligo's 3' riboguanines and the cDNA deoxycytosine overhang (Fig 1, Step 3), the MMLV reverse transcriptase switches templates and continues ...

What Type Of Template Switching Oligos TSOs Are Compatible With NEB

Rapid amplification of cDNA ends RACE 1 is an established strategy used to determine the transcription start point s TSP and the 5 untranslated region s of any given transcript 1 2 3 This information is important for a number of reasons including the facts that i knowledge of the upstream region from the 5 end might help to determine possible transcription regulation
