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.

Stanley 1. 1 Signal Transduction Laboratory, National Institute of Environmental Health Sciences, Department of Health and Human Services, National Institutes of Health. 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.
