Presence of hnRNP A1-related proteins in CB3 cells. (A) Immunoblotting of CB3, CB7, and DBT cell lysates with chicken polyclonal antibody against hnRNP A1 (21). The arrow indicates hnRNP A1 detected in CB7 and DBT cells but not in CB3 cells; the arrowhead indicates the protein band present in all three cell lines. (B) UV cross-linking studies of CB3 and CB7 cell lysates with MHV minus-strand leader RNA (lanes 2 and 3). The cross-linked proteins were immunoprecipitated (IP) with a monoclonal antibody against hnRNP A1 (lanes 4 and 5). Lane 1 contained RNA only. Sizes are shown in kilodaltons.
