immunofluorescence examination of cells infected with wild-type virus , h5ts125 , and h5ts149 ( a second , unique dna-minus mutant ) showed that immunologically reactive dna-binding protein was barely detectable in h5ts125-infected cells at 39.5 degrees c , whereas this protein was present in wild-type- and h5ts149-infected cells , that the protein made at 32 degrees c in h5ts125-infected cells lost its ability to bind specific dna-binding protein antibody when the infected cells were shifted to 39.5 degrees c , and that if h5ts125-infected cells were shifted from the restrictive temperature to 32 degrees c , even in the presence of cycloheximide to stop protein synthesis , immunologically reactive dna-binding protein reappeared .
