The reverse genetics technologies that have recently been developed for mice have provided new tools to probe gene function in vivo. Unfortunately these powerful systems often require the analysis of large numbers of DNA samples. The genetargeting technology requires screening of embryonic stem-cell clones and later of the mice themselves, the latter also(More)
The amino acid sequence of the gene for the peplomer protein of the vaccine strain M41 and the Beaudette laboratory strain M42-Salk of avian infectious bronchitis virus (IBV) have been derived from cDNA sequences. As found with other coronaviruses, the peplomer protein carries the epitopes eliciting neutralizing antibodies. The gene encodes a primary(More)
Coronavirus spike protein genes were expressed in vitro by using the recombinant vaccinia virus expression system. Recombinant spike proteins were expressed at the cell surface and induced cell fusion in a host-cell-dependent fashion. The intracellular transport of recombinant spike proteins was studied. The half time of acquisition of resistance to(More)
We describe a technique for the systematic inactivation of nonessential genes within the genome of a herpesvirus without the requirement for phenotypic selection. This technique is based on the insertion of an oligonucleotide containing translational stop codons at a random site within a large cloned viral DNA fragment. Mutant virus is then reconstituted by(More)
The accurate forecasting of storm surges is an important issue in the Netherlands. With the emergence of the first numerical hydrodynamic models for surge forecasting at the beginning of the 1980s, new demands and possibilities were raised. This article describes the main phases of the development and the present operational set-up of the Dutch continental(More)
