WebDec 10, 2024 · In polysome profiling, the separation of heavy polysomes starts to lose its accuracy when the number of ribosomes associated with an mRNA exceeds seven or eight. In ribosome profiling, the length of footprints is much smaller (~30 nts) than that of RNA fragments generated by standard RNA-seq methods. Webpolysome-profiling is the preferred technique. A technical challenge during polysome-profiling is that the pool of efficiently translated mRNA is collected in a large volume (often >3 ml) that is spread across 5-10 fractions (depending on the volume of the gradient and the volume of the collected fractions). This is commonly solved by that
