[Abstract]  The Ribo-ELISA was originally developed to elucidate the basis for the ribopuromycylation method (RPM)-based detection of ribosome bound nascent chains. The Ribo-ELISA enables characterization of the translational status of ribosomes, and can be applied to the discovery of super-ribosomal complexes with novel ribosome associated macromolecules that are isolated by physical fractionation in sucrose gradients or other methods.

Analysis of Direct Interaction between Viral DNA-binding Proteins by Protein Pull-down Co-immunoprecipitation Assay

[Abstract]  This protocol analyzes the direct interaction between two DNA-binding proteins by pull-down co-immunoprecipitation. One of the proteins is overexpressed in E. coli as HA-tagged recombinant protein and cell-free extracts are immunoprecipitated in HA-affinity resin. Cell extracts are treated with nuclease to degrade DNA and RNA, which rules out nucleic acid-mediated indirect interaction. Then, a second immunoprecipitation step is performed using the purified putative partner protein. ...
