WebJun 1, 2024 · The protozoan parasite Leishmania donovani (L.donovani) causes visceral leishmaniasis, a chronic infection which is fatal when untreated.Herein, we investigated whether in addition to altering transcription, L.donovani modulates host mRNA translation to establish a successful infection. Polysome-profiling revealed that one third of protein … WebFeb 1, 2024 · Polysome-profiling is commonly used to study genome wide patterns of translational efficiency, i.e. the translatome. The standard approach for collecting efficiently translated polysome-associated RNA results in laborious extraction of RNA from a large volume spread across multiple fractions. This property makes polysome-profiling …

http://html.rhhz.net/SWJSTB/html/2024-7-222.htm WebPolysome profiling by sucrose density gradient centrifugation is commonly used to study the overall degree of translation (messenger RNA to protein synthesis). Traditionally, the method begins with synthesis of a 5–10 mL sucrose gradient onto which 0.5–1 mL of cell extract is layered and centrifuged at high speed for 3–4 h in a floor-model ultracentrifuge.
WebMar 18, 2024 · A successful polysome profiling should show clear 40S subunit, 60S subunit, 80S monosome, and several polysome peaks. The polysome peaks represent the RNAs bound to increasing number of ribosomes (>=2). The robustness of polysome peaks is dependent on the proliferation state of the cell samples and varies between different cell … Web诺禾致源成立于2011年，专注开拓前沿分子生物学技术和高性能计算在生命科学研究和人类健康领域的应用，致力于成为全球领先的基因科技产品和服务提供者。
