Detection of reactions of the purified Nc and 3CL proteins with the respective SUMO-fusion antibodies. The purified SARS-CoV proteins were detected on the Coomassie blue stained 12% SDS-gel (A) and the Western blots were probed with the SUMO-3CL antibody (B) and with the SUMO-Nc antibody (C). The amounts of the purified proteins loaded for the SDS-gel and the Western blots were 4 and 2  μg, respectively. Arrowheads highlight observed positions of respective SARS protein bands.
