Ribosomal Profiling by Gradient Fractionation of Cell Lysates

Ribosomal profiling is a widely used technique for deep sequencing of ribosome-protected mRNA and for measuring ribosome status in cells. It is a powerful method that is typically employed for monitoring and measuring protein translation status and ribosome activity. Also, it has been used for monitoring the ribosomal stress-responsive events in the ribosome activity. Furthermore, this approach enables understanding of translational regulation, which is invisible in most proteomic approaches. Moreover, this method is known as an important approach for biological discovery such as identification of translation products. Hence, this methodology will be useful for studying cellular events engaging in ribosome assembly, ribosome biogenesis, ribosome activity, translation during the cell cycle, cell proliferation, and growth as well as the ribosomal stress response in mammalian cells.
