From a cDNA library made from fatbody of immunized Hyalophora cecropia pupae, a full-length clone corresponding to basic attacin was isolated. The corresponding amino acid sequence suggests that basic attacin is synthesized as a 233-residue preproprotein. This was confirmed by cloning the cDNA fragment encoding the basic attacin in the baculovirus(More)
A cDNA fragment encoding the human tissue-type plasminogen activator was inserted into the baculovirus Autographa californica nuclear polyhedrosis virus downstream from the polyhedrin promoter. The induction kinetics of t-PA was followed, after infection of Spodoptera frugiperda cells, at both mRNA and protein levels. Fibrinolytically active plasminogen(More)
A cDNA fragment encoding preprocecropin A was inserted into the baculovirus Autographa californica nuclear polyhedrosis virus downstream of the polyhedrin promoter. The gene was expressed in recombinant-infected last instar larvae of Trichoplusia ni and in diapausing pupae of Hyalophora cecropia. The identity of the recombinant product was established by(More)
The recent occurrence in the USA of deliberate release of virulent Bacillus anthracis in letters sent to three media corporations and to the American senate has led to a great anxiety in Sweden and elsewhere in Europe. Numerous letters have been suspected to contain B. anthracis spores and several have contained powder of different types. In none of the(More)
