Entemplate Switching Oligo

Entemplate Switching Oligo - The TSO or template switch oligo is an oligo that hybridizes to untemplated C nucleotides added by the reverse transcriptase during reverse transcription

In addition the 5 RACE RT reaction contained 0 5 M of T primer 5 oligo dT stretch 30 bp long and 0 5 M of template switching oligo TS short see Fig 1A and the 3 RACE reaction contained 0 5 M of T primer 3 see Fig 1A The reactions proceeded for 90 min at 42 C

Entemplate Switching 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 ...

Answer The TSO template switch oligo is an oligo that hybridizes to untemplated C nucleotides added by the reverse transcriptase during reverse transcription The TSO adds a common 5 sequence to full length cDNA that is used for downstream cDNA amplification The TSO is used differently in the Single Cell 3 assay compared to the Single

Amplification Of CDNA Ends Based On Template Switching Effect And Step

Template switching is believed to happen in a sequential process involving nontemplated addition of three protruding nucleotides CCC to the 3 end of the nascent cDNA which can then anneal to the matching rGrGrG 3 end of the template switching oligo TSO allowing the reverse transcriptase RT to switch templates and continue copying

Oligo Synthesis ATLANTIS BIOSCIENCE

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

Template Switching Oligos SMART Seq TSO YouTube

The cDNA synthesis and amplification protocol contains two steps In the first step cDNA is synthesized using an RT primer that contains an adaptor of known sequence at the 5 end This primer in conjunction with a template switching oligo TSO generates cDNAs containing adaptor sequences at both the 5 and 3 ends

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

Here, we describe a fast, simple method for constructing full-length cDNA libraries using SMART technology. This novel procedure uses the template-switching activity of Moloney murine leukemia virus (MMLV) reverse transcriptase to synthesize and anchor first-strand cDNA in one step. Following reverse transcription, three cycles of PCR are ...

Structural Basis For Template Switching By A Group II Intron Encoded

In this study we describe the application of nucleotide isomers that form non standard base pairs in the template switching oligo to prevent background cDNA synthesis When such bases are added to the 5 end of the template switching TS oligo they inhibit MMLV RT from extending the cDNA beyond the TS oligo thus increasing cDNA yield by
