Pulldown assay to assess interaction of in vitro-assembled capsids with recombinant tegument protein pUL48. In vitro-assembled capsids were added to GST, GST-tagged pUL48N (amino acids 1 to 411), or GST-tagged DYNLT3 (dynein light chain rp3) immobilized on glutathione-Sepharose beads. Interacting complexes were subsequently eluted and separated by SDS-PAGE (12%). (A) Immunoblot with monoclonal anti-pUL19 antibody as a marker for capsids plus pUL35 (C) and capsids minus pUL35 (C−) shows the presence of pUL35 containing capsids coeluting with GST-tagged DYNLT3 but not GST or GST-tagged pUL48N. (B) Coomassie blue stain gel confirming presence of GST-tagged proteins eluted from glutathione-Sepharose beads and also equivalent amounts of input C and C− capsids. The position of capsid proteins in the input capsid lanes are indicated.
