Para alguien de acá, esto significa que en el futuro los diagnósticos podrían apoyarse en análisis más finos sin necesidad de equipos muy costosos. El método es más rápido y más accesible, pero por ahora es una herramienta de laboratorio: todavía no hay un uso médico directo que se pueda aplicar en un hospital.","quienFirma":"bioRxiv · preprints","confianza":"preprint","consulta":null},"sello":{"hash":"a24949fd967c97f6f6926d32a06c45536c8acc12d0d83c59d364a2cddd600d92","sello":"fa66b1f8a3c9854e85939406a03881017307dfb1f7c57e32a7a81307762a0510","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6573046,"aleatorio":"f71b3db032f12c8ae2d90f38aa37ddc03a4bd072f8a3317f2962e831c62e695d","tiempo":"2026-10-21T22:40:00.000Z"},"nist":{"cadena":2,"pulso":1993728,"salida":"DBB029F00A75EEAA9AF69BB0B3207AD12D5A4EDD2136CB35D25CB332980962472F1AFBB0B247EB7DF6BE52045BC8A63F1D14E2719075ECD2BA39DE673005A0E1","tiempo":"2026-10-21T22:39:00.000Z"},"noAntes":"2026-10-21T22:40:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 21 22:40:37 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"RAPPL-Seq Enables Rapid, High-Sensitivity Ribosome Profiling of Scarce Samples","descripcion":"Ribosome profiling is a powerful method for transcriptome-wide monitoring of translation activity in vivo, but its use is limited by lengthy protocols, reliance on specialized equipment and inefficient recovery of ribosome-protected fragments (RPFs). To overcome these challenges, we developed RAPPL-Seq, a magnetic bead-based affinity capture method that enables fast and efficient RPF isolation. RAPPL-Seq achieves high recovery efficiency, short processing time, and robust performance with limited input material. It is broadly applicable across multiple sample types, including cell lines, primary tissues, and human biospecimens. RAPPL-Seq can also be paired with translation inhibitors to char","pubDate":"2026-10-21","url":"https://www.biorxiv.org/content/10.64898/2026.10.20.760540v1?rss=1"},"indexado":"2026-10-21T22:39:37.287Z"}}
