Polysome profiling是什么
Polysome profiling is a technique in molecular biology that is used to study the association of mRNAs with ribosomes. It is important to note that this technique is different from ribosome profiling. Both techniques have been reviewed and both are used in analysis of the translatome, but the data they generate … See more The procedure begins by making a cell lysate of the cells of interest. This lysate contains polysomes, monosomes (composed of one ribosome residing on an mRNA), the small (40S in eukaryotes) and large (60S in … See more It is possible to use this technique to study the overall degree of translation in cells (for examples ), but it can be used much more specifically to study individual proteins and their mRNAs. As an example shown in the lower portion of the figure, a protein that … See more WebDec 23, 2024 · 针对这一假想，研究者通过polysome profiling、AHA-Click、双荧光素酶报告系统等实验，证明了在METTL5缺失的细胞整体翻译水平下降。 生化试验进一步证实翻译起始因子与成熟核糖体结合减弱，与翻译起始相关的p70-S6K磷酸化水平降低，细胞内整体翻译效 …

WebJan 9, 2024 · Abstract. Polysome-profiling is commonly used to study translatomes and applies laborious extraction of efficiently translated mRNA (associated with >3 ribosomes) from a large volume across many fractions. This property makes polysome-profiling inconvenient for larger experimental designs or samples with low RNA amounts.
