WebAug 26, 2024 · To develop a cell type-specific assay for visualization of local translation sites, we envisioned combining the ‘RiboTag’ system (Sanz et al., 2009) of Cre-dependent HA-tagged Rpl22 (eukaryotic ribosomal protein L22, hereafter referred to as eL22-HA) with the RPM assay (David et al., 2012; Figure 1A).Based on the premise that elongation … WebHarringtonine run-off assay. Harringtonine inhibits de novo translational initiation, allowing ribosomes engaged in elongation to run-off their messages while limiting re-initiation post-termination. Harringtonine was added for 0 or 180 s and the increase in sub-polysomes relative to polysomes was calculated.

WebThe run-off assay uses a DNA template cut with a restriction enzyme downstream of the transcription start site. It simply works on creation of a site in the DNA template in which the RNA polymerase falls off. This terminates the transcription at a certain point. The assay uses a radio-labeled rNTP precursor.
