<li class="subpheader" >Purpose</li>
The purpose of this protocol is to detail the RIBOsome profiling via IsoTachoPhoresis (Ribo-ITP) protocol described in Tonn et al. 2021 to maximize execution and reproducibility in other laboratories. Here, we detail all reagents and materials needed, steps to take for experimental setup, and the Ribo-ITP protocol, and general considerations.
