Analysis of Direct Interaction between Viral DNA-binding Proteins by Protein Pull-down Co-immunoprecipitation Assay
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 Knife Rack are immunoprecipitated in HA-affinity resin.Cell extracts are treated with nuclease to degrade DNA and RNA, which rules o
