CapTrap-Seq: A platform-agnostic and quantitative approach for high-fidelity full-length RNA transcript sequencing
commercial samples obtained from Ambion: Ambion is a brand of life science research products and technologies, mainly focused on RNA products. It is owned by Thermo Fisher Scientific, a company that provides a variety of scientific research products and services. Therefore, \"total RNA commercial samples obtained from Ambion\" refers to RNA samples purchased from this brand for research purposes. CapTrap cDNA library preparation: CapTrap cDNA library preparation is a long-read sequencing protocol that selectively enriches 5'-capped transcripts by capturing the 5' caps of transcripts. This protocol uses Poly(A) tail selection to specifically target mRNA, and a 5' cap-specific oxidation reaction coupled to biotin-streptavidin to capture the 5' cap structure. The captured mRNA is then converted to cDNA and the library is prepared with 5' and 3' specific linkers to enrich for full-length libraries. CapTrap is particularly useful for studying transcription start sites, alternative splicing, and post-transcriptional modifications. Capture Long-Read Sequencing (CLS): The CLS library preparation protocol combines targeted RNA capture using streptavidin and biotin-based probes with third-generation long-read sequencing technologies like ONT and PacBio. This method allows for the preparation of sequencing libraries that can selectively enrich specific regions of the transcriptome, enabling the identification of novel transcripts and splice variants with high accuracy and coverage.
